Electric Fusion Welding(EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld. How is EfW steel formed?How is EfW steel formed?EFW steel pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible.What is EFW steel pipe - pipelinedubai

Contact us for product details. Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet.Differences Between ERW and EFW Steel PipeHigh-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW steel pipe is the abbreviation of electric fusion erw efw saw stainless steel welded pipesDifferences between ERW Steel Pipe and HFW Steel PipeHigh frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.

In both processes, raw steel is first cast in a more workable starting form. It is then shaped into a pipe by stretching out the steel into a seamless tube or by pressing the ends together and sealing them with a weld.Welded vs. seamless steel pipe American Piping ProductsERW and seamless steel piping exist as alternatives today largely due to historical perceptions. Generally, welded pipe was considered inherently weaker because it included a weld seam. Seamless pipe lacked this perceived structural flaw and was considered safer.
