SS400 Seamless carbon steel pipe
Hot-rolled seamless steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipes.
In addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipes, also includes carbon thin-wall steel pipe, alloy thin-wall steel pipe, stainless thin-wall steel pipe, special-shaped steel pipe.

Product details

Hot-rolled steel pipes are delivered in hot-rolled or heat-treated condition;

Hot rolled seamless steel pipe production process:

Tube blank → heating → perforation → three-high skew rolling and continuous rolling → Stripping → sizing → Cooling → straightening → hydraulic test → marking → lever effect seamless steel pipe in storage will be detected.

Cold-drawn seamless steel pipe production process:

Tube blank → heating → perforating → heading → annealing → pickling → oiling → multi-pass cold drawing → Tube blank → Heat treatment → straightening → hydraulic test → marking → storage. The wall thickness of cold-drawn seamless steel pipe is better than that of hot-rolled seamless steel pipe, and the surface roughness is also some.
