ASTM A106 Hot rolled seamless steel pipe Thickness 1.24 36.5 mm

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.

Hot rolled can destroy the casting structure of steel ingot, refine the grains of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; Bubbles, cracks and porosity formed during pouring can also be welded under high temperature and pressure.

Hot rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

1.Most underground pipelines are used for transportation, underground water is extracted during Gai Lou, and boiler hot water is used for transportation.
2.Machining, bearing sleeves, machining mechanical parts, etc.
3.Electrical: gas transmission and water power generation fluid pipeline.
4.Anti-static tubes of wind power plants.
