Spiral welded pipe production line

Production line introduction: The spiral welded pipe production line is designed to manufacture spiral welded pipes ,either from the same size of the steel strips to different diameters of pipes or from different widths of steel strips to the seam diameter of pipes . As the key equipment of the line ,the forming mill is used to roll metal strips continously into spiral tube blanks ,applying the theory of three-roll plate bending machine ,and then weld them into spiral pipe through one-side welding ,both-side welding or high frequency welding During the design it absorbed the advantages of spirally welded pipe equipment both at home and abroad. Its forming process was of “three roll formation plus external control roll adjustable formation”. The welding process was of “double wire submerged arc automatic welding”. For the raw material quality the welded pipes produced by this train were of those with X70 18mm thickness and maximum diameter φ 2400mm . For the control of this mill train full digital A.C. frequency variation, D.C. speed regulation and PLC control, etc. were adopted. Compared with the former spiral steel pipe equipment it had bigger improvement. Such pipe making equipment designed and manufactured is the most advanced technical installation designed through our effort in the country at present. Jiangyin Eternal Heavy Industry Co., Ltd owns the excellent technical personnel and advanced machining facility, our products have been exported to many countries. We cordially invite our customer to make a visit and discuss our mutual co-operation.
