ASTM 5115 5120 5140 4140 4120 1020 1045 Stkm11A Gear Alloy Seamless Steel Tube/Round Hollow Structural Steel Pipe
Hot-rolled seamless steel pipes are generally produced on automatic pipe rolling units. After inspecting and removing surface defects, the solid tube blank is cut to the required length with the end face of the perforated end of the tube blank as the center, and then sent to the heating furnace for heating and perforated on the piercing machine. While piercing, continue to rotate and advance. Under the influence of the rollers and the end, the tube blank is gradually hollowed out, which is called a capillary tube. Then it is sent to the automatic pipe rolling machine for continuous rolling, and the sizing machine is used to determine the diameter, and the homogenizer is used to level the wall thickness to meet the specification requirements.
