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)
