High-Precision Cold Drawn Welded (CDW) & DOM Tubing Manufacturer
Cold Drawn Welded (CDW) tubes, widely recognized in North America as DOM (Drawn Over Mandrel) tubing, are manufactured by cold drawing an Electric Resistance Welded (ERW) tube through a die and over a mandrel. At Glob-el, we utilize advanced cold drawing technology to eliminate the internal weld flash, resulting in a tube with exceptional dimensional accuracy and a flawless surface finish.
Our DOM/CDW steel tubes perfectly conform to the rigorous EN 10305-2 standard, offering superior mechanical properties and strict concentricity that are essential for critical engineering and automotive applications.
Why Choose DOM / CDW Tubing?
Ultimate Concentricity: Outstanding wall thickness uniformity compared to standard seamless tubes.
High Tensile Strength: The cold working process significantly enhances the yield and tensile strength.
Cost-Effective: Provides a tighter tolerance and better surface finish, reducing downstream machining costs.
Flawless Surface: Smooth internal and external surfaces (ID/OD) ready for further treatment.
Typical Applications
Automotive steering columns and shock absorbers
Hydraulic cylinder barrels and pneumatic components
Heavy equipment and agricultural machinery frames
High-speed shafts, bushings, and mechanical sleeves
