Electrical Resistance Weld Steel Pipe - China
price: contact company for price
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.
