In cooperation with Bergische Universität Wuppertal we have produced a knowledge floater on the subject of HFI welded steel pipe. In a straightforward, easily understandable style, it serves as an introduction to longitudinal welding using the high frequency induction process.[price]Welded Pipe Manufacturing Methods SAW, ERW, EFW & [steel]Oct 14, 2016 · In this video, you will learn about Welded Pipe Manufacturing Process such as SAW, ERW, EFW & HFW.. Welded Pipes are manufactured from Plate or from continues Coil or strips. To manufactured welded pipe, first, Plate or coil is rolled in the circular section with the help of plate bending machine or by a roller in the case of continues process.[price]Seamless Pipe VS ERW Pipe permanentsteel[steel]The pros and cons of ERW pipeWelded pipes are cheaper than seamless (ERW HFI type), as they are manufactured using steel coils as feedstock in less complex manufacturing plants. Welded pipes have shorter lead times than seamless pipes, as the manufacturing base is larger.
The high frequency induction (HFI) resistance pressure welding technique for longitudinal welding. The endless strip passes through rolling stands where it is shaped to an open pipe, which runs through a high frequency inductor consisting of a metal coil with single or multiple windings.[price]Difference between ERW, SSAW, LSAW Sunny Steel[steel]Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small diameter high pressure natural gas pipeline, used for a small number of long distance gas pipeline, the vast majority of long distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).[price]Electric Resistance Welded(ERW)and High Threeway Steel[steel]Electric Resistance Welded(ERW)and High Frequency Induction (HFI)Welded pipe Originally this type of pipe, which contains a solid phase butt weld was produced using resistance heating to make the longitudinal weld (ERW), but most pipe mills now use high frequency induction heating (HFI) for better control and consistency.
