Description
DOM Seamless Tubes
DOM Tubing (Drawn over Mandrel) is a cold drawn 1020 to 1026 or ST52.3 grade seamless steel tube to drawing to size. Cold drawing DOM to size allows for higher yield and tensile strengths. In comparison to other tubing, DOM is produced to more exact OD and ID tolerances. This allows for minimal machine time and has the highest strength possible.
DOM tubing
l Stocked and produced various size range
l Cut to length service available
l Suitable to hone sizes
l Custom sizes available upon request
l All the common off road sizes available
Benefits of DOM Tubing (Drawn over Mandrel):
l Uniform wall thickness with close OD and ID tolerances
l Uniform grain structure and controlled hardness
l High Yield and Tensile Strength
l Smooth and Clean OD and ID surfaces
l OD and ID concentric
l Excellent machining characteristics
APPLICATIONS
l Hydraulic Cylinders
l Auto and Truck Axles
l Suspension parts and shock absorbers
l High Speed Shafts and rollers
l Bearings and Spacers
l Roll cages
l Agricultural components and many other machined tubular parts.
l Pre-honed tube
Quality Standards:
l EN10305 Steel Tubes for Precision Applications Seamless Cold Drawn Tubes
l DIN 2391 Seamless Precision Steel Tubes
l ASTM A519 Seamless Carbon and Alloy Steel Mechanical Tubing

*Calculation of Design Pressures for Alternate Tubing Materials
*Design pressures for alternate tubing materials may be calculated using the Lame formula as follows: P=S((D2-d2)/(D2+d))where:
D= nominal outside diameter of tubing
d= nominal inside diameter of tubing
P= design pressure
S= allowable fiber stress of material at 4:1 design factor
