Product Description

Seamless Cold Drawn Steel Tube General seamless steel pipe production process can be divided into cold drawing and hot rolling two, cold-rolled seamless steel pipe production process is generally more complicated than hot-rolled, tube first to be three-roll rolling, after extrusion to be carried out Sizing test, if the surface is not responding to the crack after the tube to go through the cutting machine for cutting, cutting into a length of about one meter of the blank. And then enter the annealing process, the use of acidic acid for acid pickling, pickling should pay attention to whether the surface of a large number of foaming produce, if there is a large number of blistering that the quality of steel pipe can not meet the corresponding standards. The appearance of cold-rolled seamless steel pipe is shorter than hot-rolled seamless steel pipe, cold-rolled seamless steel pipe wall thickness is generally smaller than the hot-rolled seamless steel pipe, but the surface looks thicker than thick-walled seamless steel pipe, the surface is not too More rough, caliber no too much burr.Pipe Carbon Steel
