A513 DOM Tubing (Drawn Over Mandrel)

Precision Welded Cold Drawn Over Mandrel, a.k.a. “DOM Tubing” Mechanical Carbon Tubing  a513 or dom pipe. NOTE: DOM tube is actually not “pipe” at all, though it pipe is frequently referred to as pipe. Because of its unique characteristics, DOM Tubing is used in applications requiring exceptional strength-to-weight ratios. As a result, you will find DOM tubes in use as hydraulic cylinders for automotive, 4 x 4 vehicles, heavy equipment, and agricultural machinery. Similarly, uses range widely for a diverse variety of components;  plungers, barrels, cylinders, etc.  Also, you will find it used as integral parts of moving components like high-speed shafts for textile and paper mills.

Karay is a dom tubing supplier. We stock precision steel tubing of many different dimensions including hard-to-find sizes, i.e. heavy wall tubing, large diameter and small sizes as well.

“DOM Mechanical Tubing is the engineers’ choice for where high strength, superior finish, close tolerances, and concentricity is required.”

A513 DOM Steel Tubing Specifications

• ASTM A513 T5
• DOM
• SRA
• Produced OD x ID, 20′-24′
• Uniform length
• CBQ
• Alloy Tube
• Grade C1020
• Grade C1026

Karay Metal’s A513 DOM Tubing covers electric-resistance hot or cold rolled carbon steel as specified. In particular, characteristics include minimum wall variation, eccentricity and concentricity resulting in a superior surface, i.e. surface density, and close tolerance.

DOM Tubing Characteristics

• Easy to Weld, Form, Machine, Carburized, and Cut
• Close Tolerances and Mechanical Properties
• Excellent Surface Finish
• Uniform Wall Thickness

FACTS: “DOM” refers to the tubes’ finishing process and NOT the metal type. Unlike Seamless Steel Tubes, DOM does have a seam, though virtually invisible to the eye. Initial manufacturing stage is identical to ERW tubing (Electric Resistance Welded) though unlike ERW the “Flash” weld is removed and then rolled over a mandrel in the final finishing stage.

The metallurgical analysis of Karay Metal’s Drawn-Over-Mandrel tube is consistent with industry standards. Below you will find the chemical composition in specificity.
