Difference of ERW and EFW - articlesfactory erw efw spiral seam welded steel pipe

Seam welded steel pipe in the form of divided Longitudinal and spiral welded pipe. Longitudinal production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than the Longitudinal, can narrow the billet production of large diameter pipeDifferences Between SAW and ERW Pipe | Winsteel GroupThere are many kinds of pipes in the carbon steel pipe. You will see the weld steel pipe and seamless steel pipe. And in the welded steel pipe, you will find different methods of forming processes, such as erw, LSAW, SSAW. So first, lets see what the differences between saw pipes and erw pipe are.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.

A seamless pipe is manufactured by drawing a solid steel billet through a piercing rod. Welded pipes are produced by cutting, bending, welding coils (ERW) or steel plates (LSAW).Welded Pipe Manufacturing Methods - SAW, ERW, EFW & Double seam saw pipe is havening a two weld seam opposite to each other. Both the seams are welded from inside and outside of the pipe. In the case of high thickness pipe, multiple pass welding is done. In a spiral saw pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe.differentce between ERW pipe and EFW pipeERW 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. Here is a spec for steel pipe: There is a perpetual dispute whether seamless is much better than bonded.
