Jun 29, 2017

Hot-rolled carbon steel pipe, low, 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 pipe.

Cold-rolled (dial) carbon steel pipe In addition to the general steel pipe, low pressure boiler steel pipe, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipes, but also include carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel thin-walled pipe, profiled steel

Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, Cold rolled seamless steel tubes can be up to 6mm, wall thickness can be up to 0.25mm, thin-walled tube diameter can be to 5mm, wall thickness is less than 0.25mm, cold rolling than hot rolling size precision.
