Once the welding is done, the excess weld material from outside and inside of the pipe is removed with the help of trimmer tools. However, the product is still often referred to as ERW pipe, even though the weld may have been produced by the HFI / HFW (High Frequency Welded Pipe) process.Introduction to Welded Pipe Manufacturing - The Process In Electric Resistance Welding (ERW) process, pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are: 1. See more on theprocesspiping erw hfw welded carbon balustrade steel pipeHow is welded pipe manufactured?ERW / EFW or HFW Welded Pipe Manufacturing Process. Less thickness pipe, mainly ERW / EFW or HFW welded pipe are formed by continues rolling method. In this method, a flat metal strip from the strip coil is feed into the series of roller assembled in line. These rollers gradually form the strip in the circular section.See all results for this question
