Manufacturing procedure

DOM steel tubing is manufactured from electrical resistance welded hollows and cold drawn through a die and over a mandrel, improving surface finish, mechanical properties and dimensional accuracy of both outside and inside diameters. DOM is a high-quality, cost-effective choice for demanding applications and machined parts because of its special characteristics:  Combined with reliable weld integrity, Maximum concentricity, and Minimal wall variation.

Advantages

• Improved Dimensional Accuracy
• Improved Physical Properties
• Improved Surface Finish
• Straightening, Complete Dimension, and Non-Destructive Inspection are Integral to the Process
• Lower Machine Costs
• Mass Savings in High Strength-to-Weight Ratio Applications
