Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical spiral of steel and the production process where the difference? Shanxi spiral welded pipe mill manufacturers of steel pipes and spiral production process where the difference? Spiral Pipe is a strip coil for raw materials, often warm extrusion molding hydraulic press, automatic two-sided double-wire submerged arc welding process of spiral seam welded steel pipe. (1) raw materials that strip, wire hydraulic press, the flux. Go through rigorous physical and chemical testing prior to investment. (2) strip head and tail docking, single or double wire submerged arc welding, in the rolled steel by automatic submerged arc welding. (3) before forming the strip after flattening, cutting, trimming, planing, surface cleaning and transportation to the curved side. (4) the use of electrical contacts on both sides of pressure control conveyor cylinder pressure to ensure the smooth delivery of the strip. (5) the use of internal or external control roll forming. (6) with gap control device to ensure that the weld gap to meet the requirements of hydraulic welding machine picture, diameter, volume and the wrong side of the weld gap have been strictly controlled. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical difference of pipe and spiral pipe production process where (1) there is a continuous acoustic testing marks the site of the weld, manual ultrasonic and X-ray review, if there are defects after repair again after destructive hydraulic test machine supply, until the confirmation defect has been eliminated. (2) where the strip butt weld pipe and spiral weld intersects with D-type connector, and all through the X-ray television or film examination. (3) After each pipe hydrostatic test pressure radial seal. Test pressure and time by a steel pipe pressure microcomputer detection device is strictly controlled. Test parameters are automatically printed records. (4) pipe end machining, so that the end vertical slope altercation and accurate control of the blunt edge. Also known as spiral or helical spiral steel pipe equipment, is the low carbon steel or low alloy steel strip by a certain helix angle (called molding angle) rolled into a tube and then seam welded pipe made It can be produced with a narrow strip of large diameter steel pipe. Hydraulic machine manufacturers, Islamabad hydraulic press, Huaxin Cheng electromechanical provided by Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. (www.tyhxc.com) strong, credible, and other industries in other Jinzhong accumulated a large number of loyal customers.
