Straight Saw Cut: 12.7mm to 7,925.0mm.
Cut & Chamfered: 30.0mm to 2,000.0mm
Drawn Over Mandrel tubing is used for a variety of applications and industries. The most common uses for DOM tubing is machinery, hydraulics, Automotive Drive Shafts/Steering Column Assemblies, motorcycle frames, bearings, and much more. Of course, these are just a few examples of what it is used for. This type of tubing creates a seamless connection, unlike a welded tube.
We can develop solutions with the objective of offering the greatest benefit to the customer. Either by tailor made products, or standard cold drawn tubes. Meeting the customer requirements and specifications to our best abilities.
Current available to supply standards:
· ASTM A513 Type 5 & Type 6 (DOM)
· ASTM A519 CW, [Cold Worked] (CDS)
· JIS G 03445 –E-C or –S-C
· EN 10305-2, EN10305-1
· ASTM A178 Boiler (Flux) Tubes
· SAE J525 Welded Cold Drawn Low-Carbon Steel Tubing Annealed for Bending and Flaring
· SAE J536 Welded Flash-Controlled Low-Carbon Steel Tubing Normalized for Bending, Double Flaring, and Beading
Tube has no further heat treatment after cold drawn, this condition has high strength and low elongation, giving a harder but brittle condition. Good for Straight tube/cylinder not suitable for bending or forming processes
Tube has a heat treatment process that exceeds the normalization temperature, resetting all residual stress and normalizing the weld area.
Tube has a low temperature heat treatment after cold drawing process, relieving some stress maintaining some of the high strength but a bit higher formability.
Tube has a high temperature heat treatment after cold drawing process, softening the material to have better formability but lower tensile and hardness.
Tube has a high temperature heat treatment with a controlled atmosphere furnace, after cold drawing process, softening the material to have better formability but lower tensile and hardness. This process maintains the surface condition and gives a bright finish.
Material is pickled after cold drawing process to leave a clean surface without phosphate or lubricant layered, then the tube is coated with rust preventive oil.
