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.

How to choose spiral welded pipe according to your needs?

 How to choose spiral welded pipe (SSAW) according to your needs?

1. Understand the basic parameters

Before choosing a spiral welded steel pipe, it is crucial to understand the following basic parameters:

Diameter: The diameter of the steel pipe is usually determined based on the needs and flow rate of the conveyed material.

Wall thickness: Wall thickness determines the load-bearing capacity and impact resistance of the steel pipe. Depending on the use occasion, such as underground, underwater or on the surface, the choice of wall thickness will also vary.

Material: The material of the steel pipe is usually related to its corrosion resistance, wear resistance and temperature resistance.

2. Analyze engineering requirements

Every project has its specific needs. For example, oil pipelines may require special anti-corrosion treatment, while urban water systems pay more attention to the safety and reliability of pipelines.

3. Consider the usage environment

Temperature: Steel pipes used in high temperature environments need to have good high temperature resistance.

Chemical Exposure: In chemical plants or other locations susceptible to chemical contamination, steel pipe needs to have excellent chemical stability.

Geographic location: For example, salt spray environments in coastal areas can cause corrosion to steel pipes.

4. Choose the right model

There are many types of spiral welded steel pipes, which can be classified according to their production process and functions:

Basic type: suitable for general building structures and mechanical structures.

Anti-corrosion type: with special anti-corrosion coating, suitable for humid and chemical environments.

High-pressure type: suitable for high-voltage transmission lines, such as oil and natural gas transmission.

5. Communicate with suppliers

Many suppliers offer customization services and are able to produce steel pipes according to a customer's specific needs. Ensure adequate communication with suppliers to clarify the specific requirements of the project.

6. Consider cost factors

In addition to the direct steel pipe costs, you should also consider the associated costs of transportation, installation, maintenance and replacement. Choosing the right steel pipe model and specification can result in significant savings throughout the life of the project.

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.
