Common standards for steel casing

 Steel casing is a thin-walled steel pipe used in oil pipelines, oil wells, and natural gas wells. It can withstand high pressure, high temperature and corrosive media. The following are some of the major steel casing standards.

1.API5CT

API5CT is a petroleum casing standard formulated by the American Petroleum Institute, including different grades of casing, such as H40, J55, K55, N80, L80, C90, C95, P110 and Q125.

2. ISO 11960: Petroleum casing standard formulated by the International Organization for Standardization, similar to API 5CT, including different grades of casing.

3.GB/T 9711.1: Petroleum casing standards formulated by the China National Standardization Organization, including L175, L210, L245, L290, L320, L360, L390, L415, L450, etc.

4.SY/T6194: Petroleum casing standard formulated by China Petrochemical Industry Standards, including Casing and Tubing types, used at different depths and conditions of oil wells.

These standards specify the size, chemical composition, mechanical properties, quality requirements, etc. of oil casing to ensure its safety and reliability during oil and gas extraction.

Types of steel casing

Steel casing can be divided into: conduit, surface casing, technical casing and oil layer casing according to usage.

Guide sleeve: Mainly used for drilling in oceans and deserts to separate seawater and sand to ensure smooth drilling.

Surface casing: Mainly used for the first drilling, drilling through the soft surface stratum to the bedrock. In order to seal this part of the stratum from collapse, it needs to be sealed with surface casing. Surface oil casing protection drill

The well is protected from contamination by shallow water and gas layers, supports wellhead equipment and maintains the weight of other layers of casing.

Technical casing - Separates the pressure at different levels to facilitate the normal flow of drilling fluid and protect the production casing so that anti-burst devices, anti-leak devices and tail pipes can be installed in the drilling well.

Reservoir oil casing (production casing): extracts oil and natural gas from reservoirs beneath the earth's surface and is used to protect drilling wells and separate drilling mud into layers. When producing oil casing, the outer diameter usually ranges from 114.3 mm to 508 mm.

Steel grade of steel casing

According to the strength of the steel itself, steel casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Different well conditions and well depths require different steel grades. In corrosive environments, the casing itself is also required to have corrosion resistance. In places with complex geological conditions, the casing is also required to have anti-collapse properties.

How to choose the right steel casing?

When selecting steel casing, there are several factors to consider:

1. Material: High-quality anti-corrosion and wear-resistant materials should be selected, such as polyurethane, chlorinated polyvinyl chloride, polyester, etc., to ensure the anti-corrosion and wear-resistant properties of the casing.

2. Specifications: According to the diameter and length of the oil pipe that needs to be protected, select the casing of the corresponding specifications to ensure that it can completely cover the oil pipe.

3. Thickness: Thickness is one of the important indicators to measure the quality of casing. A casing with moderate and uniform thickness should be selected to ensure its strength and wear resistance.

4. Production technology: Choose casings with exquisite production technology, tight braiding layer, smooth surface and no burrs to ensure their quality and reliability.

Comparison of bending properties of round tube and square tube

 Basic introduction to carbon steel round tubes and square tubes:

Round tubes and square tubes are common metal pipes, widely used in construction, machinery, transportation and other fields. The cross-sectional shape of round tubes is circular, while the cross-sectional shape of square tubes is square or rectangular. The manufacturing processes of round tubes and square tubes are different, so their bending properties are also different.

Comparison of bending properties of round tubes and square tubes:

1. Bending radius

For the same material and wall thickness, round tubes have a smaller bending radius than square tubes. This is because the cross-sectional shape of the round tube is circular, and the geometric characteristics of the circle make it easy to adapt to curves when bent. The cross-sectional shape of the square tube is rectangular. When it is bent, there will be a deviation in the internal and external angles, thereby increasing the bending radius.

2. Bending capacity

Round tubes have higher bending capacity than square tubes. This is because the cross-section shape of the round pipe is circular and the central axis is symmetrical, so the force is even when bending, and its load-bearing capacity is relatively stable. The cross-sectional shape of the square tube is rectangular and the central axis is asymmetrical. It is easy to have a flat bottom and a convex top, which leads to buckling and plastic deformation during bending, thereby reducing its bending load-bearing capacity.

Applicable occasions for round tubes and square tubes:

According to the above analysis, it can be seen that round tubes have advantages in bending performance compared to square tubes. Therefore, round pipes are more suitable for use in situations where frequent curve bending or pipe support and fixation are required. Square tubes are suitable for use in situations where pressure resistance, torsion resistance, shear resistance, etc. are required. For example, square tubes are needed in places such as building frames, brackets, doors and windows that need to bear loads and direction uncertainty.

Conclusion:

To sum up, there are differences in bending properties between round tubes and square tubes. Although round pipes have small bending radius and high bearing capacity, they are more suitable for use in curved bends or pipe support and fixed situations; square pipes are suitable for bearing loads in many different directions and forms. In practical applications, appropriate pipe materials need to be selected according to their respective characteristics to ensure project quality and safety.

What is the difference between seamless pipe and ordinary steel pipe?

 Seamless tubes (SMLS) are significantly different from ordinary steel pipes in many aspects. The following is a comparison from four aspects: definition, manufacturing process, performance and application fields.

1. Definition

Seamless tube: Made from a single piece of metal, there are no welding gaps or cast connections, so its strength and durability are higher than ordinary steel pipes. The quality of seamless steel tube is usually higher because more steps and processes are required in its production.

Ordinary steel tube: Usually welded from steel plates or strips, with welds (welded steel pipe). During the manufacturing process of ordinary steel pipes, two or more steel plates can be connected by welding.

2. Manufacturing process

Seamless tube: Manufacturing seamless steel tube requires a series of complex process steps, such as selecting appropriate raw materials, heating, plastic deformation, cooling, straightening, etc. Especially seamless steel tubes used in high-pressure or highly corrosive environments require additional heat treatment and surface treatment steps.

Ordinary steel tubes: The manufacture of ordinary steel pipes mainly relies on welding technology. The steel plates or strips are cut and welded according to the designed drawings, and finally formed into the required shape and size.

3. Performance differences

Seamless tube: Since seamless steel tube has no welds, its overall strength and durability are better. It is more resistant to high pressure, high temperature, and highly corrosive environments and can meet more demanding working environments.

Ordinary steel tube: Ordinary steel pipe has relatively poor strength and durability due to the presence of welds. However, its manufacturing cost is low and it is suitable for some occasions that do not require high performance.

4. Application fields

Seamless tube: Seamless steel tube is mainly used in pipeline systems in petroleum, natural gas, chemical industry, electric power and other industries, as well as in machinery manufacturing, construction and other fields. In these fields, high-quality steel pipes are required to withstand the effects of high pressure, high temperature and highly corrosive environments.

Ordinary steel tubes: Ordinary steel tubes are mostly used in basic engineering facilities, such as bridges, building structures, water pipes, etc. These fields do not have high requirements on the strength and durability of steel pipes, and more emphasis is placed on cost factors.

In summary, there are significant differences between seamless tubes and ordinary steel tubes in manufacturing processes, performance and application fields. When choosing which type of steel pipe to use, the decision needs to be made based on actual needs and application environment.

What are the Safety Measures for Oil Pipelines?

 What are the types of oil pipelines?

Generally speaking, there are two types of oil pipelines: carbon steel pipes and oil-resistant rubber hoses. Many of the fixed oil pipelines we see now mostly use carbon steel pipes, while oil-resistant steel pipes play an important role in the temporary loading and unloading of active parts of oil transportation facilities. In carbon steel pipes, it can also be divided into seamless steel pipes and welded steel pipes according to different manufacturing methods, and seamless steel pipes are also divided into hot rolled and cold drawn.

What are the safety measures for oil pipelines?

Oil pipeline is an important part of modern energy transmission, it carries a large amount of oil and natural gas resources, so safety issues are particularly important. In order to ensure the safe operation of petroleum oil pipelines, a series of strict safety measures need to be taken. This article will introduce some common oil pipeline safety measures.

1. Quality engineering design and construction.

The design and construction of petroleum oil pipelines should follow relevant standards and specifications to ensure the strength, stability and corrosion resistance of pipelines. In the design stage, factors such as transmission distance, transmission capacity, geographical environment and geological conditions need to be considered to determine the appropriate pipeline diameter, thickness and support structure to ensure that the pipeline can withstand the expected pressure and external environment.

2. Regular pipeline monitoring and maintenance.

Oil pipelines require frequent inspections and maintenance to detect and deal with potential problems. Leak detection is the key link. By using high-precision leak detection technologies, such as gas detection, liquid flow meters and smart sensors, pipeline leaks can be detected and located early. In addition, using remote sensing technology and drones and other modern technical means, it is possible to conduct a comprehensive inspection of the pipeline, find out the abnormal condition of the pipeline in time, and take corresponding maintenance measures.

3. Anti-corrosion and heat preservation measures.

Due to the high temperature and corrosiveness of oil and natural gas, oil pipelines need to take measures for anti-corrosion and heat preservation to prolong the service life of the pipeline and ensure safe operation. Common anti-corrosion insulation materials include epoxy coating, polyethylene film, rock wool, etc. These materials can effectively isolate the influence of the external environment and media, and protect the pipeline from corrosion and temperature changes.

4. Emergency response planning and training.

Developing an emergency response plan is the key to ensuring rapid response and action in the event of an emergency. The plan should include procedures for dealing with various accidents such as spills, fires and explosions, specifying responsibilities and action steps. In addition, train relevant personnel to improve their emergency response capabilities and accident handling skills to minimize losses and risks.

5. Safety supervision and regulatory compliance.

The government and relevant regulatory agencies should strengthen the safety supervision of oil pipelines, formulate and implement relevant regulations and standards, and require enterprises to abide by safety regulations and operating procedures. Violations should be punished in accordance with the law to maintain the safety and stability of the entire oil pipeline industry.

6. Environmental awareness and measures.

Oil pipeline transportation may involve some sensitive environmental areas, such as waters, forests and ecological protection areas, so it is necessary to attach great importance to environmental protection. During the design and construction stages, damage and pollution to the environment should be avoided as much as possible, and the pipeline layout should be planned reasonably. During the operation period, an environmental monitoring system should be established to regularly detect and evaluate the environmental impact during transportation, and take corresponding measures to repair and compensate.

7. Information technology application.

With the development of information technology, its application in oil pipeline safety management is becoming more and more important. For example, through the establishment of a remote monitoring system, real-time monitoring and data analysis of pipeline operation status, timely detection of abnormal conditions and take measures. At the same time, big data, artificial intelligence and other technologies are used to predict and evaluate the operational risks of pipelines, and take measures in advance to avoid accidents.

8. International cooperation and experience sharing.

Oil pipeline safety is a global issue, and countries need to strengthen cooperation and experience sharing. Through joint formulation of standards, technical exchanges, and training cooperation, etc., we will promote the improvement of the safety management level of oil and oil pipelines, jointly meet challenges, and ensure the safety and reliability of energy transmission.

To sum up, oil pipeline safety measures cover many aspects, including engineering design, monitoring and maintenance, anti-corrosion and heat preservation, emergency response, regulatory compliance, environmental protection, information technology application, and international cooperation. By taking these measures comprehensively and effectively, the safe operation of oil pipelines can be ensured to the greatest extent and reliable support for energy supply can be provided.

Causes of rust and discoloration of carbon steel pipe and preventive measures

 The reasons for the rusting of carbon steel pipes are as follows:

1. Medium that causes product corrosion

Moist air, hand sweat or dirt from product contact, water, acid, alkali, salt and chemical gases remaining on the metal surface may cause metal corrosion.

2. Corrosion resistance of metal

Metals that are prone to rust include pig iron, carbon steel, and structural alloy steel. Stainless steel, high-temperature alloys, and titanium alloys will rust in special environments.

3. Parts prone to rust

The parts that are easy to contact, adhere to and accumulate corrosive substances include grooves, seams, holes, edges, joint surfaces, hand contact surfaces, parking surfaces, etc., or rough surfaces, newly processed surfaces, sandblasting polished surfaces, etc., which are prone to corrosion. rust.

4. Corrosion-prone environment

Generally speaking, processing workshops such as pickling, heat treatment, electroplating, welding, painting, electrolysis, etc. are more prone to corrosion than mechanical processing workshops, because these workshops have a large amount of corrosive media.

Protection methods for carbon steel pipes:

The rust of carbon steel has a great influence on its appearance and service life, so rust prevention is very necessary. The following are several common carbon steel rust prevention methods:

1. Passivation

Rust is prevented by passivation. Passivation treatment is to form a protective oxide layer on the surface of carbon steel, which can prevent the steel from being further corroded by the environment.

2. Surface coating

Surface coatings such as galvanizing and painting can effectively prevent carbon steel from rusting and form a protective film on the surface, which can resist corrosion from the external environment and improve the hardness and durability of the surface.

3. Cement coating

Cement coating is another method for carbon steel to prevent rust. Although cement will absorb water, it will directly form a protective layer on the surface of the steel pipe. Therefore, cement coating is also a method of rust prevention.

4. Anti-rust oil treatment

The anti-rust oil added with anti-rust agent can prevent the rust of carbon steel well, and can be used as anti-rust treatment for engineering machinery, automobile engine parts and so on. The use of high-density grease and preservatives can prevent oxygen from entering the surface of carbon steel, thereby reducing the occurrence of oxidation reactions.

5. Electronic rust removal technology

The application of electronic rust removal technology can completely remove the rusty substances generated on the surface of carbon steel without changing the physical properties of the steel, so as to achieve the purpose of rust prevention.

Factors affecting the welding quality of ERW welded pipe

 With the development of ERW welded pipe technology, its application fields continue to expand. ERW welded pipe uses the skin effect and proximity effect of the current to heat the edge of the tube blank to the welding temperature for extrusion and welding. Compared with seamless pipe, it is obvious that ERW pipe has a weld seam, and its performance depends largely on the quality of the weld seam.

The factors affecting the quality of welds are more complicated, including the chemical composition of raw materials, inclusions, banded structures, sickle bends, and edge burrs, which will all affect the quality of welds.

a. Inclusions and banded structures have a great influence on the impact toughness and flattening performance of welds. Excessive inclusions are easy to accumulate in the heat-affected zone of welds and easily form crack sources to cause cracking.

b. When the sickle bend and the edge burr are serious, it will cause misalignment, arc strike, weld deviation, inclusions are difficult to discharge, etc., which will reduce the quality of the weld.

Factors of high-frequency welding process level. The temperature, speed, extrusion amount and opening angle during welding will all affect the quality of the weld.

If the temperature is too high, the burr does not have a raised shape, the weld seam is flat, and the temperature is too low, the top of the outer burr is not smooth, and there is no intermittent raised shape on the burr line; the faster welding speed, it is easier to ensure the quality of the weld seam; in general, The amount of extrusion should refer to the wall thickness, and it is better to control it at about 5.0mm. For thick-walled pipes such as 10mm or more, the extrusion amount can be increased by 0.5-1mm; as the diameter and thickness of the pipe change, the opening angle should also be adjusted appropriately.

The stability of high-frequency welding is also the key to the stability of weld quality. Too many impurities and burrs on the edge of the plate will cause instantaneous short-circuit ignition during high-frequency welding, and local cold welding of the weld. To prevent this defect, regular inspections should be made. Whether the installation of the high-frequency coil is reliable, whether the coolant is filtered clean, whether the welding opening angle is appropriate, whether the edge burrs of the coil are removed, and then strengthen the inspection of water pressure and ultrasonic to strictly control the quality of the steel pipe.

The heat treatment process is also one of the influencing factors. Heat treatment generally adopts online intermediate frequency weld heat treatment. The influence of the length of the air-cooled section after intermediate frequency heating on the quality of the weld is easily overlooked. Too high water entry temperature will cause a sharp decline in the impact toughness of the weld. Low, the impact toughness will also decrease, it is necessary to consider the running speed of the production line to determine the length of the air-cooling section.

Weldability of high carbon steel pipe

 High-carbon steel refers to carbon steel with W(C) higher than 0.6%, which has a greater tendency to harden and is more sensitive to the formation of cold cracks. High-carbon steel has poor weldability and requires special welding processes to ensure joint performance. In welded structures, it is generally rarely used.

High-carbon steel pipes are mainly used for machine parts that require high hardness and wear resistance. In heavy machinery manufacturing, welding problems of high-carbon steel parts will also be encountered. When welding high-carbon steel, it is necessary to comprehensively analyze possible welding defects , and take corresponding welding measures.

Weldability of high carbon steel pipe:

1. Welding method

High-carbon steel pipes are mainly used in structures with high hardness and wear resistance. The welding methods include submerged arc welding, electrode arc welding, and brazing.

2. Welding materials

High carbon steel pipe welding generally does not require the strength of the joint and the base metal. Electrode arc welding uses a low-hydrogen electrode with strong desulfurization ability, low metal hydrogen content, and good toughness. If the strength of the weld metal and the base metal is required, the corresponding level should be selected. If it is not required, choose a low-hydrogen electrode whose strength level is lower than that of the base metal. If the base metal is not allowed to preheat during the welding process, you can choose the heat-affected zone, austenitic stainless steel electrode, to prevent cold cracking, Obtain an austenite structure with strong crack resistance and good plasticity.

3. Groove preparation

Reduce the fusion ratio, limit the mass fraction of carbon in the weld metal, use U-shaped or V-shaped grooves during welding, and pay attention to cleaning the grooves and the oil and rust on both sides.

4. Warm up

Structural steel electrodes should be preheated before welding, and the temperature should be controlled at 250 ° C ~ 350 ° C.

5. Interlayer processing

In multi-layer multi-pass welding, the first welding is welded with a small diameter electrode and a small current. Usually, the workpiece is placed in a semi-vertical welding or by using the electrode to swing laterally, and the entire heat-affected zone is heated in a short time to Get preheating and warming effects.

6. Post-weld heat treatment

After welding, the workpiece is placed in a heating furnace for stress relief annealing, and the temperature is kept at 650 °C.

Due to the high carbon content and poor weldability of high carbon steel pipes, cracks are prone to occur in welding. Therefore, it is necessary to choose a reasonable welding process to reduce the occurrence of welding cracks and enhance the performance of welded joints.

The reason of sandblasting before anticorrosion of steel pipe

 Sand blasting, also known as sand blasting, is a surface treatment method that uses high-speed jets of sand to polish the metal surface to remove rust, scale and dirt, while improving the roughness of the metal surface. Why is steel pipe (such as seamless pipe or welded pipe) required to be sandblasted before anticorrosion?

1. Improve the roughness of the steel pipe surface

Sandblasting can effectively improve the surface roughness of the steel pipe and create good conditions for coating adhesion. The adhesion between the coating and the steel pipe surface mainly depends on mechanical anchorage. The surface of the steel pipe after sand blasting and external treatment forms many tiny unevenness, which increases the contact area between the coating and the steel pipe surface, thereby improving the adhesion of the coating.

2. Remove surface dirt and scale

During the production, transportation and storage of steel pipes, various dirt will adhere to the surface, such as rust, scale, oil and so on. These impurities will affect the adhesion between the coating and the steel pipe surface and reduce the anti-corrosion effect. Sandblasting can effectively remove surface dirt and ensure that the coating is tightly bonded to the steel pipe surface.

3. Improve the stress state of the steel pipe surface

Sandblasting can effectively improve the stress state of the steel pipe surface. During sand blasting, the sand particles have a uniform impact force on the surface of the steel pipe, causing slight periodic deformation on the surface of the steel pipe, thereby reducing the residual stress on the surface and prolonging the service life of the steel pipe.

4. Improve coating quality

The surface roughness of the steel pipe after sandblasting is increased, and the adhesion between the coating and the steel pipe surface is improved, making the coating more firm. At the same time, sandblasting can make the coating more closely bonded to the surface of the steel pipe, reduce the air gaps and gaps under the coating, and improve the sealing and corrosion resistance of the coating. The steel pipe coating after sandblasting is more uniform and smooth, which not only improves the anti-corrosion performance of the coating, but also improves the overall aesthetics of the steel pipe.

5. Enhance the wear resistance of the coating

Sand blasting can make the surface of steel pipe more uniform and smooth, which is beneficial to the uniform distribution of dry coating. The coating after sandblasting is more compact, and the wear resistance is significantly improved, thus prolonging the service life of the steel pipe.

6. Improve production efficiency

Sand blasting is a fast and efficient surface treatment method that can greatly improve production efficiency. Compared with traditional manual rust removal and grinding, sandblasting is faster and more efficient, saving manpower and time costs.

To sum up, the sandblasting treatment of steel pipes before anticorrosion is of great significance to improve the quality and effect of anticorrosion coatings. Sand blasting can not only remove surface dirt and improve coating adhesion, but also improve the stress state on the surface of the steel pipe and improve the wear resistance of the coating, thereby prolonging the service life of the steel pipe. Therefore, sandblasting is an indispensable key link in steel pipe anticorrosion engineering.

Manufacturing Loss Rate of Seamless Steel Pipe

General mechanical equipment is lossy, and the production of seamless steel pipes also has a certain loss. The standard and loss rate of seamless steel pipe loss are still relatively large. The specific loss situation can be calculated, and what is the calculation method? Let's find out together with the seamless steel pipe manufacturers.

What is loss rate?

The loss rate refers to a certain rate of loss determined by the production enterprise after checking the consumption of the unit product and the total material consumption according to the normal defect and loss in the process of producing products. The attrition rate is most commonly used in the cost calculation of factories and merchants. The higher the attrition rate, the more unfavorable it is for factories and merchants.

The formula for calculating loss rate:

There are two calculation formulas for the wastage rate, which are used for the calculation of material quotas and the procurement of materials by enterprises.

1. Loss rate=(loss/net consumption)×100%

Expressed in terms of consumption: consumption = net consumption × (1 + loss rate)

The formula used to determine material consumption quotas. The net consumption refers to the materials directly used in construction and installation projects, and the loss refers to unavoidable construction waste and material loss. It is mainly used for various project budgets and final accounts, which is common throughout the country and has industry standards and legal significance.

2. Loss rate=(loss/consumption)×100%

Expressed as consumption: consumption = net consumption ÷ (1-loss rate)

Not a formula for determining material consumption quotas. Generally, it is the formula used by the construction unit to calculate the purchase quantity of materials. The value is determined by itself according to the construction technology level of the unit, construction conditions, source and method of material procurement, and the processing characteristics of the material itself. It is a self-use formula.

Manufacturing loss rate of seamless pipe:

1) For example: What is the cutting loss, rolling waste and burning loss of an annual output of 150,000 tons of seamless steel pipes?

The proportion of seamless steel pipe cutting loss, rolling waste and burning loss mainly depends on the size, quality, specification, coating, etc. of the raw material, so you need to analyze specific issues. But in general, the rolling loss rate can reach about 11%, the burning loss rate can reach about 4%, and the cutting loss is generally controlled below 5%. In addition, heat treatment processing will bring a certain amount of burning loss, and the specific ratio will vary. In addition, when producing all kinds of seamless steel pipes, product quality testing must also be considered, and large losses may also occur during quality testing. It is generally required that steel pipes that are not subject to such testing should account for about 10% of the total products.

2) What is the loss rate when the seamless pipe is perforated?

When the seamless steel pipe is perforated, the general loss rate is about 2%. It depends on the wall thickness, the loss of the thick wall is smaller, and the loss of the thin wall is larger.

3) In the production of seamless steel pipes, what is the loss of general heat treatment?

There are many heat treatment methods for heat treatment, and the loss will vary. If it is the most common annealing heat treatment, the loss is about 1%. If it is oxygen-free annealing, there is basically no loss, because the surface of the tube is not oxidized, does not grow oxide scales, and does not peel off, so there is no loss. Other heat treatments, such as quenching and tempering, also depend on the specific process and method.

Usually, the straight pipe loss is generally about 3%, the bend pipe is about 6%, and the gradient pipe is generally about 10%. For example: when the iron rod is processed into a round shaft, the loss is small because of the simple process; but when it is processed into a square shaft, the loss rate may be large due to the complicated process.
