Hot rolled seamless steel pipe feature

Carbon seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam. The most advantage is increasing the ability of withstanding higher pressure.n improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel pipe.

Widely used for liquid, gas, and steam services both above- and below ground services.
