Performance Comparison of ERW and Spiral Steel Tube

 　　Performance comparison of carbon ERW steel pipe and spiral steel pipe:

　　1. Overview

　　The welding of ERW steel pipe is the skin effect and proximity effect of high-frequency current. The process of using high-frequency current and induced high-frequency current (rising at the end of the 20th century) resistance to heat and melt the edge of the tube blank, and apply squeezing force to weld together process.

　　The welding of SSAW steel pipe is a process in which the weldment, welding wire and flux are melted by the arc under the flux layer, and the molten flux forms a slag to isolate the air and the molten pool from contact, thereby forming a welding joint.

　　There are two main differences:

　　A) SSAW has metal fillers such as wire flux, but ERW does not.

　　B) SSAW forms a weld pool, ERW does not form a weld pool, only a molten state is formed at the edge of the billet.

　　2. Advantages of ERW steel pipe

　　A) Short weld length, HAZ is smaller than SSAW;

　　B)High geometric accuracy;

　　C) If the burr removal device is used, the weld reinforcement is lower than SSAW, and the conveying resistance is small;

　　D) The production efficiency is high, and the welding speed is 15-20m/min, which is more than 10 times that of SSAW.

　　3. Advantages of SSAW steel pipe

　　A) The direction of the weld avoids the direction of the main stress when the pipeline is under pressure;

　　B) A single defect on the weld is less framing;

　　C) Steel strips with the same width can be used to produce steel pipes with different outer diameters, or steel strips with different widths can be used to produce steel pipes with the same outer diameter.

　　4. Welding performance comparison

　　A) ERW has fast heating speed, highly concentrated heat, and no filler metal. It is not possible to use wire flux to add alloying elements to compensate for the burning of alloy elements in the welding process like SSAW, and it cannot effectively improve the structure and performance of welded joints like SSAW (microalloying is the main way to refine grains. Grain refinement is the only way to increase strength and toughness at the same time).

　　B) ERW does not form a welding pool, so the welding dross ability is poor. If there is slag inclusion on the edge of the raw material, it can only remain in the weld and become a quality hazard. However, SSAW forms a welding pool, which is beneficial for slag inclusions to float in the slag.

　　C) There is no slag/gas protection during ERW welding (SSAW has slag protection formed by flux), and the welded joint structure at high temperature is easily oxidized, which makes the welded joint have a tendency to embrittlement.

　　D) ERW has the characteristics of high local heating temperature and short cooling time. The welding temperature field has a large gradient, which is prone to hardening phase and large welding stress. The plasticity and toughness of the welded joint are not ideal. Therefore, all ERW steel pipes in the country require post-weld heat treatment (Q+T or Q+N), but the domestic post-weld heat treatment process is not yet mature.

　　E) Compared with SSAW, the ERW welding speed is too fast, the edge quality of the raw material cannot be tested by NDT, and the NDT test of the weld after welding is also difficult to ensure the quality.

　　F) Since ERW is welded by pressing molten metal, it is difficult to use NDT for effective inspection. Therefore, incomplete fusion and gray spots are the problems of eRw steel pipes, which have been difficult to effectively solve for decades. Groove corrosion in ERW pipeline failure is mainly caused by unfusion.

　　G) ERW will inevitably form more “D” joints during pipeline construction, while SSAW will not. As we all know, the “D” joint is the most concentrated part of the stress, which reduces the fatigue life of the welded joint.

　　H) The residual stress of traditional SSAW pipe is relatively large, and the dimensional accuracy is not as high as ERW. (In fact, the residual welding stress of ERW is also relatively large, of course, a part of it can be eliminated if proper heat treatment can be performed). Nowadays, advanced technologies such as low residual stress forming and mechanical expansion of pipe ends are commonly used for the production of SSAW pipes, and the quality is not much different from LSAW.

　　I) Since ERW has no filler metal, there is almost no reinforcement, which is conducive to FBE or 3PE anti-corrosion treatment. SSAW steel pipe has high welding seam reinforcement, and anti-corrosion requires high welding seam shape. Pay attention to the sudden transition between the welding seam and the base metal, forming a right angle or an acute angle. SSAW steel pipe factory generally adopts external welding double wire welding, the front wire guarantees the penetration, and the rear wire mainly guarantees the shape of the weld to achieve a smooth transition. Judging from the steel pipes produced by our factory, there is almost no right angle or acute angle.

Customer choose Xinyue Steel because of trust

 　　The establishment of trust will be affected by many factors, the most important is "reliable". It is essential for qualified products and normative operation of a company. However, The trust is difficult in the international trade due to the distance limit the meeting and on-the-spot testing operation.

　　The regular New Zealand customer who has been cooperating with Xinyue for nearly two years. There are more than dozens of orders, and none of them has any quality, delivery time and other issues. Xinyue has given absolute support to customer in terms of delivery time, quality and project construction solution in their piling project, which has won good reputation for sheet pile construction and gained more project construction cooperation opportunities.

　　The products of this order are more than 300 tons of steel sheet piles with the length of 8 meters, 9 meters and 10 meters. The construction of the project is imminent, which means that the delivery time is tight and particularly important, inventory is the best option which can be satisfied for project, while the length of 8m and 10m is not the stock length of steel sheet pile. Based on the trust of the previous cooperation, the customer does not hesitate to sign the project contract with Xinyue. Long term partner business relationship, mutual benefit and win-win cooperation, Xinyue decided to process the 18 meter inventory sheet pile into the required length for our client.

　　Within a week, the operation of the order is completed. However, as we all know, from September 2020, the world logistics transportation has suffered a serious impact, such as the shortage of containers, the explosion of cargo space, the rejection of containers and other problems. Our Logistics Department overcome various difficulties, strive to reduce the impact of various factors of price increase, finally we delivery materials smoothly for customer.

　　In the international market development of Xinyue for more than ten years, there are quite a number of loyal regular customers. Their support and trust have played a very important role in the development of Xinyue. Xinyue uses high-quality products and professional service to support customers expand rapidly.

　　We are so appreciate that we have you, will with our partner all the way !

Concerned about whether the rebar peak season can be sustained

 　　It is now mid-November, and the spot market is still showing peak season characteristics, which validates the view that we have repeatedly talked about the peak season delay. "Golden Nine and Silver Ten" is the traditional peak season for consumption, but the spot market in September this year was "not busy". We proposed that the peak season demand was postponed to October and November.

　　However, what needs attention is the sustainability of peak season demand. With reference to previous years, demand will decline after mid-to-late November. According to the predictions of relevant state agencies, the cold air activities affecting our country are frequent and strong this winter, and a wide range of low-temperature rain and snow may occur in northern my country. The low temperature and rain and snow in the northern region mean the loss of construction conditions, but also a decline in the demand for rebar. According to the weather forecast, there will be a large-scale cooling in the second half of this week.

　　The core factor pushing up the price of rebar is strong demand. Once the demand weakens, the price peaking and falling will be a high probability event.

　　Supply pressure still needs to be guarded

　　In addition, supply pressure remains the primary negative factor to beware of. Supply pressure comes from domestic resource supply and the conversion of import and export resources.

　　The domestic resource supply can be analyzed from two perspectives: policy and profit. This year's fall and winter production restriction policy has a very limited impact on rebar output; the recent increase in steel prices has significantly improved corporate production profits, which will increase corporate production enthusiasm.

　　In terms of the transformation of import and export resources, the main reasons are the decrease in exports and the increase in imports. Imports are divided into two parts: steel imports and billet imports. The latest customs data show that from January to October, my country's steel exports decreased by 10.665 million tons year-on-year, steel imports increased by 7.225 million tons year-on-year, and imported steel billets increased by about 12.62 million tons. Overall, domestic steel supply increased by more than 30 million tons.

　　In short, it is recommended that investors who hold long orders of rebar futures gradually stop profit.

main characteristics of the development of the private iron and steel economy

 　　The operation of the iron and steel industry and the main characteristics of the development of the private iron and steel economy

　　Since the beginning of the year, in the face of the huge impact of the sudden new crown pneumonia epidemic and the complicated and severe domestic and foreign environment, the steel industry has conscientiously implemented the “six stability” and “six guarantees” decisions and deployments of the Party Central Committee and the State Council, adhered to the prevention and control of the epidemic and stable production and operation Grasping with both hands has achieved good results.

　　Main features of the operation of the steel industry

　　First, the overall operation of the steel industry remained stable. Since the beginning of this year, the iron and steel industry has shown a steady growth in production, a slight rebound in prices, and a gradual improvement in economic performance. According to data from the National Bureau of Statistics, the output of crude steel, pig iron, and steel products nationwide was 781.59 million tons, 665.48 million tons, and 964.24 million tons, respectively, up 4.5%, 3.8%, and 5.6% year-on-year.

　　According to statistics from the Metallurgical Chamber of Commerce, the output of crude steel, pig iron, and steel produced by private steel companies from January to September was 498 million tons, 407 million tons, and 690 million tons, respectively, representing a year-on-year increase of 5.8%, 4.9%, and 6.6%, respectively. National average; crude steel output accounts for 62.8% of the national output.

　　Second, the economic benefits continued to improve. According to the National Bureau of Statistics, the national steel industry realized a total profit of 157.7 billion yuan from January to September, a year-on-year decrease of 18.7%.

　　Statistics of key private steel companies from January to September by the Metallurgical Chamber of Commerce: Sales revenue reached 2060.5 billion yuan, a year-on-year increase of 6.8%; realized profits and taxes of 147 billion yuan, down 5.6% year-on-year, of which realized profits of 92.2 billion yuan and paid taxes of 54.8 billion yuan. Key private steel companies pay more than 200 yuan per ton of steel; the main reason for the decline in profits and taxes is the large increase in the price of raw materials such as iron ore; the debt ratio of enterprises has dropped from 61.8% last year to 58.2% this year, a decrease of 3.6 percentage points; In general, the operation of private steel has improved, and the main indicators are better than the national average.

　　However, in the economic operation of the steel industry, it is also facing difficulties such as maintaining high raw and fuel prices, rising costs, and falling exports.

　　Third, the steel industry is showing new changes. There are three outstanding changes: 1) The share of crude steel production in the world is increasing, and it was 53% in 2019. This year, under the two-way influence of domestic production increase and foreign production reduction, there will be a greater increase, which is expected to reach about 60%. 2) The full release of steel production capacity driven by strong domestic demand has also strongly supported the rapid recovery of the national economy. It is expected that the annual steel consumption and output will exceed 1 billion tons. 3) The overall image of the steel industry is undergoing positive changes. Over the years, the steel industry has been overwhelmed by the "two highs and one capital" hat, but the steel industry insists on keeping its eyes inward and resolutely implementing the Party Central Committee and the State Council’s recommendations on the supply of steel. The principles and policies of structural reforms and the firm green development concept have achieved remarkable results after long-term efforts, and have been affirmed by relevant national departments. On September 26, the director of the Department of Atmospheric Environment of the Ministry of Ecology and Environment, Liu Bingjiang, in 2020 China Steel The Energy Conservation and Emission Reduction Forum said: During the "13th Five-Year Plan" period, the steel industry has made outstanding contributions to improving the national air quality, and air pollution control has achieved positive results. Although steel production exceeds the planned target, crude steel production has increased year by year, and air pollutants Emissions have increased, but the effect of emission reduction measures has exceeded expectations, offsetting the impact of the increase in steel, and achieving "increased production without increasing pollution"; the iron and steel industry resolves the three major reductions of excess capacity, process emission reduction, and ultra-low emission transformation The effectiveness of emission control measures exceeded expectations.

High Feedback from Vietnam customer

 　　It has been nearly a year since the first cooperation relationship with this customer was established at the beginning of 2020. During one year, the customer has reordered 3 times. Highly recognized Tianjin Xinyue's quality control, resources, and ability to solve problems in a timely manner. There is no smooth sailing order. However, Xinyue relies on its own ability to make every order finally delivered smoothly.

　　The customer comes from Australia and has its own processing plant in Vietnam. After the pipes are processed, they all will be delivery and used in Australian local projects. Therefore, the steel grade has always been required to be high-steel grade C350 Australian steel grade. The biggest difficulty of this order is the specifications required are more than 5 different sizes, but the number of specifications is decades tons. The minimum order quantity for the single specification of the steel grade is generally 200 tons. Xinyue relies on its own experience in this industry in these years, combined with frequently shipped orders in Australia. Solved this big problem for customers. It saved customers a lot of capital occupation fees and the risk of inventory backlog. This month the customer returned Positive feedback was given to us with photos of some of our goods processed in Vietnam. The satisfaction expressed between the lines is enough to become the motivation for our continuous efforts.

　　For Xinyue, problems have always been used to be solved. We face the root of the problem, stand from the perspective of the customer, analyze the problem and solve the problem with the customer's interest as our interest. We Serve the world as Made-in-China.

Serve wholeheartedly and we can get customer’s trust

 　　The establishment of trust may be long-term and arduous for many people, especially for the foreign trade industry. Today with advanced information, although the authenticity of the company can be checked through Google or Facetime positioning or even the official website of the government, there are still Many customers believe that seeing is believing. Therefore, how to win the trust and favor of customers in the shortest time is a topic that we foreign trade people have always needed to study and explore.

　　The customer mentioned today is from Southeast Asia and is mainly engaged in the construction of hydrocarbon plants. At present, there is a project in hand that urgently needs stainless steel pipe EN10217-7. In the past 4 months, customers have searched all over the world, from UAE to Europe, from Europe to China, and compared more than 20 suppliers. Can't make a decision. Due to the delivery date, the customer finally reached the critical point of project procurement, and finally met Xinyue by chance. After Xinyue knew the customer's project situation and delivery requirements, starting from the inventory plan, it gave the customer a satisfactory delivery date and price, and submitted technical documents and stainless steel factory production photos.

　　Serve wholeheartedly and we can get customer’s trust

　　At the same time, due to the epidemic, customers were unable to visit our company, and a small video was made to show all aspects of Xinyue's office area and factory to give customers peace of mind. Finally, after two weeks of negotiations, the customer assured Xinyue the order.

　　The trust and recognition of customers is the greatest motivation for all Xinyue people, and we will not disappoint any expectations and trust.

The difference between 2PE anti-corrosion steel pipe and 3PE anti-corrosion steel pipe

 　　3PE anticorrosive steel pipe base materials include seamless steel pipe, spiral steel pipe and straight seam steel pipe. Anti-corrosion pipelines can be divided into two categories, lined with anti-corrosion steel pipes and outer-wall anti-corrosion steel pipes. The lining anti-corrosion mainly includes cement mortar-lined anti-corrosion steel pipe, which has more applications and lower cost. The cement mortar-lined anti-corrosion steel pipe uses the cement mortar anti-corrosion layer to protect the pipeline. Outer wall anti-corrosion pipes are more commonly used 3pe anti-corrosion pipes. The anticorrosion technology is a process of covering the outer wall or inner wall of the steel pipe with a protective effect on the pipeline itself. It can process various pipes such as straight seam steel pipe and spiral steel pipe. Among them, in order to prevent accidents such as personal injury, loss of property, etc. caused by explosion when conveying flammable and toxic fluids, Spiral Steel Pipe Plant adopts corresponding process standards to continuously meet important performance operations, and ensure quality and safety in the market during testing and measurement Use.

　　2PE anti-corrosion steel pipe: two layers of PE anti-corrosion structure for pipelines, the first layer of polyethylene (PE), the second layer of adhesive (AD), the two materials are fused together, and the thickness of each layer is the same as that of three layers of PE.

　　2PE anticorrosive steel pipe advantages:

　　1. Strong corrosion resistance, the construction side is simple and fast, and the service life can reach 30-50 years.

　　2. 2PE anti-corrosion steel pipe has extremely high tightness, long-term operation can greatly save energy, reduce costs and protect the environment.

　　3. At the same time, it has high epoxy strength, low water absorption of PE and good softness of hot melt adhesive, etc., and has high corrosion resistance.

　　4. It also has good corrosion resistance and impact resistance under low temperature conditions, and the water absorption of PE is low (less than 0.01%).

Quality assurance and prompt delivery

 　　At the beginning of 2020, Xinyue received the inquiry of more than 120 tons of seamless pipe, welded pipe and pipe fittings from its old customers in Singapore. Through the confirmation and submission of a series of technical documents and good price support, As well as the pleasant cooperation of several similar projects in the early stage, the customer did not hesitate to use Xinyue to bid. Soon after, the customer got the project. Because of the impact of the epidemic situation, the construction could not be carried out smoothly. He understood the customer's difficulties. In order to support the customer, Xinyue kept the price valid until the year. The customer was very satisfied with it, and soon after the local epidemic situation improved We confirmed the order.

　　After placing the order, the customer feedback that the terminal project progress is ahead of schedule, which puts forward higher requirements on the delivery date. All production needs to be completed within 20 days. The factory production line order scheduling has been planned in advance, and rash queue jumping may have an impact on other orders. However, in order to protect the interests of customers and meet the terminal requirements, the factory production team immediately adjusts personnel and personnel Under the condition of not affecting the normal delivery of other orders, the production priority was arranged. After 15 days of production and processing, all the production tasks of the order were successfully completed five days in advance.

　　The customer originally planned to come to China for finished product inspection, but due to the epidemic situation, he was unable to visit. After providing the self inspection report, Xinyue arranged for a third party to carry out the inspection. From the size to the appearance to Xinyue inspection report, the third party inspection was very detailed. Xinyue professional technology and production equipment, conscientious operation team, produce strictly in line with ISO quality management system and international production standards and specifications of products. Xinyue always adhere to the concept of "honesty, customer first, high quality and efficiency".

　　This is the best steel pipe brand of Xinyue: "the best price, the best quality, the best delivery time and the best service".

　　Xinyue people sincerely look forward to working with you!

　　Xinyue steel pipe serves the world and builds the world. We are looking forward to your inquiry.
