A tube forming process where the tube is drawn through a die while supported internally by a mandrel. This improves internal surface finish, dimensional accuracy, and concentricity
A welding process used to produce the initial tube before DOM drawing. Electric current heats the steel edges and pressure joins them together to form a weld seam.
The stress level at which steel begins to deform permanently. DOM tubing often has improved yield strength due to cold working during the drawing process.

Frequently Asked Questions
Manufacturers using DOM tubing typically run automated machining operations where material consistency is essential for production efficiency. Their questions often focus on dimensional precision, internal surface quality, and mechanical performance. The following topics reflect the most common technical considerations when sourcing DOM tubing for precision mechanical components.
What is the difference between DOM tubing and standard welded tubing?
DOM tubing starts as welded tubing but undergoes a cold drawing process over a mandrel that improves dimensional accuracy and surface finish. The process reduces weld seam visibility and produces tubing suitable for precision mechanical applications.
Why is DOM tubing widely used in automotive components?
The cold drawing process increases strength and produces consistent dimensions. This allows manufacturers to machine parts such as shafts, bushings, and suspension components with predictable performance and minimal variation.
Does DOM tubing still contain a weld seam?
Technically the original weld seam remains in the material, but the cold drawing process significantly refines and blends the weld zone, resulting in a uniform structure that performs similarly to seamless tubing in many mechanical applications.
Is DOM tubing easy to machine?
Yes. The refined grain structure and consistent hardness produced during cold drawing make DOM tubing highly machinable. This is one reason it is widely used for precision mechanical components.
What industries commonly use DOM tubing?
In addition to automotive manufacturing, DOM tubing is used in hydraulic equipment, industrial machinery, agricultural equipment, and mechanical components requiring high dimensional accuracy.
