Welded Steel Tube:
Drawn Over Mandrel Tubes
Drawn Over Mandrel Tubes (DOM) Drawn Over Mandrel tubes according to tubing manufacturing standards like ASTM A513 type-5 & -6 or equivalent to meet customers requirements. Drawn over Mandrel (DOM) can be an ideal choice where a high degree of dimensional accuracy is required.
Applications:
- Hydraulic cylinders
- Transmission shafts
- Steering Columns
- Suspension components
- Camshafts
- Axle Tubes
- Drive Shafts
- Jack Sleeves
- Bushings
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
Standards
- ASTM A513 Type 5
- Drawn Over Mandrel (DOM)
- ASTM A513 Type 6
- Drawn-Over Mandrel Special Smooth ID (SSID DOM)
