DOM steel tube (Drawn over Mandrel) is an electric welded tube without a weld flash. Compared to seamless tubing, DOM steel tubing provides a superior finish and wall uniformity. Before completion, all DOM tubing is drawn over a mandrel, tested for weld soundness, and retested to ensure unsurpassed product quality.

What is Steel DOM Tubing?

The drawn over mandrel (DOM) pipe and tube production process is a welding method used to create high-quality steel tubes through 1020/1026 electric resistance. The DOM namesake is derived to explain the process in which the tube and pipe are produced. DOM is not a specific metal alloy.

Steel DOM Pipe & Tube Advantages

The drawn over mandrel tubing process (DOM) creates a more concentric, uniform product that maintains tolerances closer to a customer’s specifications. DOM tubes also have superior mechanical properties, including increased hardness, tensile strength, and a good welding seam. These beneficial properties make DOM tube ideal for automotive components and mechanical parts, such as hydraulic cylinders, without requiring further machining. Further steel DOM tubing benefits include:
  • Good strength & formability
  • Excellent surface quality
  • Precision tolerances
  • Uniformity
  • Easy machinability

Steel DOM Tubing Industrial Applications

Drawn over mandrel tubing is not only used for automotive applications. It also provides many other advantageous qualities that benefit several unique industries, including:
  • Construction
  • Oil & gas
  • Agriculture
  • Energy
  • General fabrication
  • Infrastructure
  • Fluid handling
  • Machinery

Steel DOM Pipe & Tube Automotive Applications

Due to its numerous beneficial qualities, DOM tubing is used exclusively in the automotive sector for a wide range of applications, including:
  • Roll cages
  • Racecar frames
  • Shafts
  • Chassis
  • Camshaft tubes
  • Engine mounts
  • Headers
  • Struts
  • Axles

Round DOM Tube Production Method

Drawn over mandrel tubing (DOM) is produced from a specific manufacturing process that makes the seam within the tube nearly invisible. Steel DOM tubing is produced by annealing (heating), which allows it to be pulled over the tapered steel shaft (drawn over mandrel). Additionally, smoothing of the tube’s inner weld seam provides enhanced mechanical properties over standard steel.

DOM (1020 & 1025) Round Steel Tube Mechanical Properties

DOM round steel tube is mandrel drawn, producing a tube with increased dimensional accuracy and tolerances with a smooth inside and outside finish.
  • Steel DOM tubing product is ideal for applications of increased stress.
  • It is ideal for high-stress applications that require good mechanical properties, including uniformity, strength, and soundness.
  • Compared to other steel tubing, DOM tubing is transformed during the drawn over mandrel process, yielding the highest weld strength possible.
