Seamless steel pipe outside diameter * thickness specifications are usually used (unit: mm), said. Seamless steel pipe production methods can be divided into hot-rolled and cold rolled seamless steel pipe (allocated) seamless steel pipe into two categories. Hot-rolled seamless steel pipe sub-normal, low and medium pressure boiler pipe seamless steel pipe plant, high pressure boiler pipe, steel pipe, stainless steel pipe, oil cracking pipe, steel and other steel and other geological. Cold-rolled (allocated) Subject to sub-general seamless steel pipe, low pressure boiler pipe, high pressure boiler pipe, steel pipe, stainless steel pipe, oil cracking pipe, the other steel, including precision steel, carbon thin-walled steel, alloy thin wall pipe, thin-walled stainless steel, special steel pipe. Hot-rolled steel production plants seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, cold-rolled seamless steel pipe diameter can go to 6mm steel pipe plant, wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm wall thickness of less than 0.25mm, cold than hot-rolled high dimensional accuracy. In the pipeline project, when the diameter of more than 57mm, often used in hot-rolled tubes, diameter less than 57mm common cold drawn (rolled) pipe.
