All steel pipes operated by our company are in compliance with national standards, and the original bill of materials of steel mills is attached. At the same time, we supply the SA514 Grade A, B, E, F asme alloy steel seamless steel pipe, electrical Resistance Weld pipes, large diameter welded pipes ordering business of various specifications and materials and the railway and road transportation business for the majority of users.
Carbon steel pipe is more often used than alloy steel pipes. Compared with alloy steel pipe, It has the advantage of good performance with lower cost. BBN supplies SA514 Grade A, B, E, F asme alloy steel most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe, erw steel pipe and spiral welded steel pipe.
Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.
The work performance of SA514 Grade A, B, E, F asme alloy steel etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
