Difference between ERW, DOM and Seamless Tube Metal

May 12, 2015 · The seamless tube is manufactured using a process called extrusion. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube. Basically there are two types of seamless tube:Cold Drawn Seamless (CDS) normally made from SAE 1018, having precise tolerances and good surface finish Drawn Over Mandrel Tubing - DOM Round Steel Tubing Drawn Over Mandrel Tubing Drawn Over Mandrel (DOM) Round Mechanical Tubing is a cold drawn 1020 mandrel for seamless1026 electric resistance welded tube with all the flash removed prior to cold drawing. In comparison to other tubing, DOM round steel tubing is produced to more exact OD and ID tolerances, and has the highest weld strength possible. Drawn-Over-Mandrel (DOM), Electric Resistance Welded Drawn-Over-Mandrel (DOM), Electric Resistance Welded (ERW) In line with our reputation as a world supplier of tubing, at Salem Steel NA, LLC our mills manufacture high quality electric resistance welded tubing (ERW), which is further worked to produce drawn over mandrel (DOM) tubing for a range of industries and demanding applications. Our DOM tubing is created from flat sheets of raw material EP1679136B1 - Method of manufacturing seamless tube by A method for manufacturing seamless tubes by a three-roll mandrel mill, characterized in that the ratio of the inner circumferential length of the tube material to the outer circumferential length of the mandrel bar is set in the range of 1.07 to 1.17 in the last two stands, that constitute said mandrel mill, in which the tube material is
