Where the square tubes, rectangular tubes, square and rectangular pipe, large diameter Rectangular Pipe supply is particularly abundant. Our company can according to customer demand seamless cold drawn square tube manufacturers, custom manufacturing custom seamless square and rectangular tube, square tube, q345b Rectangular pipe, rectangular pipe, large diameter thick-walled Rectangular Pipe, in order to ensure product output, the company is equipped laboratories and the purchase of ultrasonic flaw detector and hydrostatic pressure testing machine and other products quality inspection equipment. Rectangular Pipe lot of flaws in the perforations and is therefore a step in the tube of the transfer function is the production of square tubes of key programs. The main difficulty piercing high alloy piercing performance is low, when necessary in order to ensure the quality of the rational choice of deformation parameters perforated. The amount of compression will result in a small perforation process becomes unstable, so critical compression child should head the previous amount of compression is generally set at around seven percent, otherwise it will not bite, even before moving to increase or card. Hot-rolled rectangular pipe, billet, plate rolling early as the raw material, and then through the furnace seamless square tube manufacturers, even when using high-pressure water, cleanup thin-walled seamless square tube surface of the phosphorus factory, then rough rolling mill, in roughing mill mainly on the head and tail cut rectangular tubes, and then in the pipeline, and then fed to the finishing mill 45, seamless square tube manufacturers, computer-controlled precision rolling. RHS layer after cooling, after rolling coiler, then curl. However, when re-curl, thickness often, and as some kind of error accuracy.
