How thick is DOM tubing?

In comparison to traditional electric welded tubing, DOM tubing is produced to extremely tight OD and ID tolerances. This type of tubing is also known to have the highest weld strength possible. DOM is manufactured in numerous sizes ranging from a 0.188” OD to 12.000” OD with wall thicknesses from 0.028” to 0.625”.

What is the tolerance on DOM tubing?

Tolerances – D.O.M. Steel Tubing

O.D. Size Range O.D. Inches
Over Under
0.500- 1.669, incl. 0.005 0.000
1.700-2.009, incl. 0.006 0.000
2.100-2.499, incl. 0.007 0.000

What does DOM mean in steel tubing?

Drawn Over Mandrel
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 steel tubing is produced to more exact OD and ID tolerances, and has the highest weld strength possible.

Is DOM tubing measured ID or OD?

Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).

How is DOM tubing measured?

As previously mentioned, tubing is measured by its outside diameter or dimensions and the wall thickness. For example, we like to use 1.75 inch x . 120-wall DOM. That has an OD of 1.75 inches and 1/8 inch wall thickness.

What grade is DOM tubing?

3 grade
DOM Tubing (Drawn over Mandrel) is a cold drawn 1020 to 1026 or ST52. 3 grade electric resistance welded tube with all the flash removed prior 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.

What type of steel is Dom?

Technically, DOM is not a type of steel tube, but rather the process in which the tube is finished. It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel.

What is Dom measurement?

Dissolved organic matter (DOM) is operationally defined as any organic matter that is able to pass through a filter. It is described in contrast to particulate organic matter (POM) retained on the filter. Traditionally, glass fiber filters with a nominal pore size of 0.7 μm were the standard.

What is Dom material?

DOM stands for Drawn Over Mandrel, and it’s a welding method used to create high-quality steel tubes through 1020/1026 electric resistance. The term DOM tubing is typically used to describe a type of a high strength steel tube.

What is DOM mild steel?

Often times you’ll see an option for Mild Steel or Chromoly. ERW (Electric Resistance Welded) and DOM (Drawn Over Mandrel) are both Mild Steel tubing and both are used in lots of applications. While both are “mild steel”, ERW is most often made from a 1010 alloy while DOM is most often 1026.

What kind of steel is used in Dom tube?

What are the different sizes of Dom tubing?

Tubular Products produces DOM tubing in one of the world’s most extensive size ranges — 0.750″ through 12.000″ OD and 0.065″ through 0.650″ wall thickness. Many intermediate metric or inch sizes may be ordered to your specifi- cations without penalty of tool costs or delivery time.

What are the advantages of a Dom tube?

After annealing to produce a uniform grain structure throughout, the tube is then cold drawn over a mandrel to give it these advantages: uniform concentricity around the central axis, better ovality, closer tolerances, denser surface, uniform wall thickness, and higher physical properties.
