Cold drawn 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.
