Production processes for Welded Pipes IspatGuru

The plates used for the longitudinally welded pipes are formed on presses having open dies for the U-ing and closed dies for the O-ing operations. The process is also called UOE forming process (U-ing, O-ing and expanding) and is used for the production of longitudinally welded large diameter pipe in individual lengths upto 18 m.Principle of High Frequency DC Resistance Welding (ERW)It is a new type of welding process that uses the skin effect and proximity effect generated by high-frequency current to connect steel plates and other metal materials. The emergence and maturity of high frequency welding technology directly promoted the huge development of the longitudinally welded pipe industry, which is a key process in the production of longitudinally welded pipe ( ERW pipe ).Petrosadid: Electric Resistance/ Fusion Welded (ERW and EFW)ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.
