1.2 specification alloy pipe putting up get smaller size and better quality seamless import t91 alloy tube, the method must be cold-rolled, cold drawn, or both combined. Shanghai t91 usually cold rolled alloy tube on two-roll mill, pipe in the hole section becomes circular hole slot and does not move the cone head consisting of rolling. Drawing is usually performed on the 0.5 ~ 100T single chain or double chain drawing machine. 1.3, the upcoming heating extrusion good squeeze tube placed in a sealed cylinder t91 seamless, extruded rod piercing rod and move together, so that the smaller extrusion extruded from the die hole. This method can produce smaller diameter steel pipe. The company specializes in Baosteel, Tianjin, Chengdu, Steel, Steel, and other well-known manufacturers of high quality seamless pipes and other metal materials. Made of 10 #, 20 #, 45 # 16Mn, 27SiMn, 12CrMoV, together with the original or a copy of the material.
