Drawn-over-mandrel (DOM) tubing is a type of tube made by cold-drawing an electric resistance welded (ERW) tube through a die and over a mandrel. This process improves the tube’s dimensional precision, weld strength, and surface finish. DOM tubing is known for its accuracy and reliable weld quality, making it a cost-effective option for various applications. Its tight tolerances allow it to be used in mechanical components with minimal or no additional processing.
Solitaire Steel offers a wide range of DOM tubing in different sizes, weights, and specifications.
The Many Purposes of DOM Tubing
DOM (Drawn Over Mandrel) tubing serves many purposes across various industries due to its strength and reliability. It is commonly used in machinery, hydraulics, motorcycle and race car frames, bearings, and farming equipment, among other applications. Unlike welded tubes, DOM tubing offers a seamless connection, making it a preferred choice for high-pressure or heavy-load applications.
This tubing is available in different sizes and specifications, including stainless steel DOM tubing, and is widely used in bushing and structural applications. Detroit Nipple Works offers a broad selection of DOM tubing, ensuring that all products meet ASTM Specification A513 with uniform wall thickness.

FAQs
Drawn Over Mandrel (DOM) tubing is a type of steel tube made by cold drawing over a mandrel for improved strength, dimensional accuracy, and smooth interior finish.
DOM tubing is strong due to the cold drawing process, which enhances its mechanical properties, such as hardness and tensile strength, while providing superior dimensional accuracy and a uniform finish.
DOM Tubing (Drawn Over Mandrel) is typically made from steel grades 1020 to 1026 or ST52.3, offering good mechanical properties and precision due to the cold drawing process.
