EFW pipe vs ERW pipe. 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. It is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can rapidly What is saw pipe?What is saw pipe?SAW pipe means Submerged Arc Welded pipe. And from different weld seam, there are two saw pipes, including LSAW and SSAW. As the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam.Differences Between SAW and ERW Pipe Winsteel Group
Seamless pipe is made from a round steel billet (solid cylindrical hunk of steel that is cast from raw steel). This billet is then heated, stretched out and pushed or pulled over a form. It is then pierced through the center with a die and mandrel which increases the inside diameter and reduces the outside diameter.
