Electric resistance welded (ERW) pipes are longitudinally welded from metal after moving it afterward. CDW pipes are produced by expelling the metal to the required length; Hence ERW pipes have a welded joint in its cross-section, while CDW pipes do not have any joint in its cross-section all through its length. Welded tubes are cold drawn over mandrel when the

What is the difference between ERW and EWW?What is the difference between ERW and EWW?I do not think the ERW/ EFW has anything to do with the homes of the metal plate for the pipe. ERW and EFW describes the manner/method/type of welding (the plate). R= Resistance and F= Combination hence you would have Electric Resistance Welded Pipe or Electric Fusion Welded Pipe. Both would be made from the exact same plate.differentce between ERW pipe and EFW pipe(plate)
