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.
