High Frequency Straight Welded Pipe Production Line ERW

What ' s The difference between ERW and HFW steel pipe?What ' s The difference between ERW and HFW steel pipe?ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes. What is ERW steel pipe?Differences between ERW Steel Pipe and HFW Steel Pipe(pipe) Why is low frequency ERW no longer used in pipe manufacturing?Why is low frequency ERW no longer used in pipe manufacturing?Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion, hook cracks, and inadequate bonding of the seams, so low frequency ERW is no longer used to manufacture pipe. The high frequency ERW process is still being used in pipe manufacturing. There are two types of High Frequency ERW processes.Introduction to Welded Pipe Manufacturing

Introduction to Welded Pipe Manufacturing - The Process

Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessIn 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.
