Seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam. It is suitable for bending and flanging. The most advantage is increasing the ability of withstanding higher pressure. So it is widely used for boiler and pressure vessel, automotive area, oil well, and equipment components.
Seamless steel pipe can be cut, threaded or grooved. And the coating method includes black / red lacquer, varnish painting, hot dip galvanization, etc.
