The company specializes in the research and development, production and sales of A709 grade 50 structural steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A709 grade 50 structural steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A709 grade 50 structural steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
S35C steel is a high-quality carbon structural steel, which has good plasticity and appropriate strength, good process performance, and acceptable welding performance. It is mostly used in normalized and quenched and tempered states. Grades included in the JIS G 4051 standard: S10C, S15C, S20C, S25C, S30C, S33C, S35C, S40C, A709 grade 50 structural steel, S45C, S48C, S50C, S53C, S55C, S58C, S09CK, S15CK, S20CK.
Pipeline steel is a kind of steel specially used for transporting natural gas and petroleum with special requirements. Why do oil and gas pipelines use pipeline steel as the transportation pipeline? Because pipeline steel has the following characteristics. First, the pipeline steel is strong, and it is not easy to break. If it breaks during transportation, the consequences are unimaginable. Second, the A709 grade 50 structural steel, pipeline steel is durable. Pipeline steel is buried deep underground for a long time and has good corrosion resistance. Third, the pipeline steel is resistant to high temperature and will not deform under high temperature.
API 5L X65 steel plate/pipes, under API 5L standard, we can regard X65 steel plate/pipes as large diameter pipes. A709 grade 50 structural steel, X65 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X65 steel pipes/plate is a higher strength, tough, weldable steel for applications in the oil and gas industry.X65 Flange Steel meets fully the mechanical property requirements of the API 5LX X65 line pipe specifications whilst maintaining a high degree of toughness and weldability.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. A709 grade 50 structural steel, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the A709 grade 50 structural steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
