DOM Tubes (Drawn Over Mandrel Tubes) are high strength precision steel tubes manufactured through the DOM process of cold drawing welded steel tubing over a mandrel to enhance the dimensional precision, surface quality, concentricity and mechanical properties. DOM Tubing is widely used in automotive, hydraulic cylinders, engineering, structural applications, heat exchangers and industrial machinery for its high strength, smooth internal finish and excellent machinability. ASTM A513 Type 5 standards, and SAE 1020 grades are common specifications. DOM Tubing is widely used in automotive, hydraulic cylinders, engineering, structural applications, heat exchangers and industrial machinery because of its superior strength, smooth internal finish and good machinability. Typical specifications are ASTM A513 Type 5 and SAE grades such as 1020.
What is DOM Tubing?
DOM Tubing is Drawn Over Mandrel steel tubing that is cold drawn in a secondary process after the initial manufacturing of the ERW (Electric Resistance Welded) tube. The DOM process involves drawing the tube over a mandrel and through a die, resulting in tighter tolerances, higher tensile strength, and a smoother finish than normal welded tubing. Drawn Over Mandrel DOM Tubes Tubing offers superior concentricity and uniformity compared to ordinary welded tubes, making it ideal for applications that require precision and durability. We supply high quality DOM Tubes in carbon steel, Stainless Steel, alloy grades and nickel alloys to suit industries worldwide. In the DOM process the tube is pulled through a die and over a mandrel to provide better tolerances , tensile strength and a smoother finish than conventional welded tubing.
Drawn Over Mandrel (DOM) Tubes Tubing is not your ordinary welded tube. It provides superior concentricity and consistency, and is the tube of choice for applications where precision and durability are required.
We provide high quality DOM Tubes in Carbon Steel, Stainless Steel, alloy grades, nickel alloys to cater the needs of industries across the globe.

DOM Process – How DOM Tubes are Manufactured
The DOM process begins with high-quality ERW steel tubing. The welded tube is then processed through cold drawing over a mandrel and die.
Step-by-Step DOM Manufacturing Process- Steel strip is rolled into tube form.
- Tube edges are welded using electric resistance welding.
- The welded tube is normalized for stress relief.
- Tube is cold drawn through a die and over a mandrel.
- Final sizing and finishing operations are performed.
- Tubes are inspected for dimensional accuracy and quality.
This process significantly improves the mechanical properties and precision of the tubing.
