Amardeep Steel Center Suppy A513 Type 5 Drawn Over Mandrel Tubing. DOM Steel Tube is made from uniformly high grade C1020 carbon steel strip that is shaped and electric resistance welded into its basic shape. After annealing to establish a homogeneous grain structure throughout, the tube is cold pulled over a mandrel to provide the following benefits: uniform concentricity around the central axis, improved ovality, closer tolerances, denser surface, uniform wall thickness, and greater physical characteristics. The cold working method works the weld region to produce a sound, dense, and homogeneous structure similar to that of the base metal.
A Dom Tube is not technically a tubing, rather it is the technique by which they are made. DOM, or Drawn
Over Mandrel, is a type of metal forming method. This technique begins with an ERW, or electrically
welded formed tube. First, the ERW is cold pulled over a die and across mandrel planes. As a result, the
die's size and angle will influence features such as Outside Diameter (OD). The Inside Diameter or ID of
Drawn Over Mandrel Tubing is determined by the Mandrel or Plug used.
Depending on its application, a DOM Tube's chemical composition could be mild steel or stainless steel.
Any alloy's usage in the fabrication of DOM Seamless or Welded Tubes will be determined by the primary
qualities required for any application. Using this metal forming method has various advantages. For
example, the cold drawing technique gives the stainless steel dom tube a superior surface polish, higher
dimensional endurance, and the strongest weld strength possible. After being cold drawn, the mild steel
dom tube is subjected to a heat treatment to modify mechanical qualities and improve properties such as
machinability and toughness.
