China ASTM Seamless Steel Precision Tube Pipe

Drawn Over Mandrel (DOM) Round Mechanical Tubing is a cold drawn 1020 / 1026 electric resistance welded tube with all the flash removed prior to cold drawing. In comparison to other tubing, DOM round tubing is produced to more exact OD and ID tolerances, and has the highest weld strength possible.

Made from 1020 / 1026 Steel

Meets ASTM A513 Type 5

Stocked Size Range: 3/16" - 14" OD; .028" - .625" wall thickness

Stocked in 20' random lengths

Cut to length sizes

Suitable to hone sizes

Imperial and metric sizes

Custom sizes available upon request

Benefits of Drawn Over Mandrel (DOM) Round Mechanical Tubing:

Uniform wall thickness with close OD and ID tolerances

Uniform grain structure and controlled hardness

High Tensile and Yield Strength

Smooth and Clean OD and ID surfaces

Excellent machining characteristics

Applications: Hydraulic Cylinders, Axles, High Speed Shafts, Barrels, Bearings, Spacers, and many other machined tubular parts.

Test reports available on request.
