Product Description

Construction Material Erw Round Steel Pipe Q235 Hollow Black Steel Pipe
 

ERW stands for Electric Resistance welded pipe. A plate rolled to become a pipe and welded using Electric Resistance Welding process. Usully for for high diameter. (cheapest process avaiable)
ERW tubing or Electric Resistance Welded tubing is not as strong as DOM tubing or Drawn Over Mandrel tubing. Usually when tube is made, it starts off as a flat sheet and this is rolled up into a tube and welded. DOM tubing is usually made the same way but there is an extra process where this tube is drawn through a die along with a mandrel to control the outer and inner diameters of the tube. This extra process strengthens the steel since it is cold formed by up to 20%. Another type of common tubing is Chrome-Moly also known as Chromium / Molybdenum Steel. This type of steel also uses the same process but has these additional elements within the steel alloy which increase strength even more. Chrome-Moly is usually used in tubing for cars and other applications over 3500 lbs.
