Dom Tubing Specs
Talk To Us – We’re Here To Help
DOM tubing is renowned for its exceptional strength and durability. It offers superior resistance to tension and bending compared to ERW tubing, thanks to its precise manufacturing process. DOM tubing features exact tolerances for both internal and external diameters, ensuring high-quality performance. Despite starting as a welded tube, the drawn-over-mandrel process creates a nearly seamless appearance and provides the highest weld strength available.
Ideal for a wide range of structural and bushing applications, DOM tubing excels in environments that demand high quality, uniformity, and strength. Whether used in challenging conditions or for critical components, DOM tubing delivers reliability and performance.
Solitaire Steel Supplier provides DOM tubing in various sizes and specifications to suit your specific needs.

FAQs
DOM tubing is specified by ASTM A513 and is commonly produced in grades such as 1020, 1026, or ST52.3. It is cold drawn, with all flash removed before drawing, resulting in higher yield and tensile strengths.
DOM tubing is preferred for its high precision and strength. Its uniform wall thickness, tight tolerances, and superior mechanical properties make it ideal for high-pressure applications and heavy workloads in industries like automotive, oil and gas, and aerospace.
The ASTM specification for DOM (Drawn Over Mandrel) tubing is ASTM A513. This specification ensures that the tubing meets the required tensile properties and dimensions, comparable to cold-drawn seamless steel tubing of the same steel grade and nominal size.
