Drawn over Mandrel (DOM) tubing is defined by 3 different dimensions:
• Inside Diameter (ID) • Outside Diameter (OD) • Wall Thickness
When ordering, only 2 of the 3 tolerances must be defined. Anchor Fasteners India Steel purchases DOM tubing, for general inventory, to the outside diameter and inside diameter.
If you do not see a size listed, please contact your Anchor Fasteners India representative.

• Many tubes with ID less than 50% of OD or with wall more than 25% of OD, or with wall over 1-1/4″, or weighing more than 90 lb./ft. are difficult to draw over a mandrel. Therefore, the ID can vary over or under by an amount equal to 10% of the wall thickness.
• For tubes with ID less than 1/2″. (or less than 5/8″ when the wall thickness is more than 20% of the OD), which are not commonly drawn over a mandrel the above footnote not applicable.
• Tubing having a wall less than 3% of the OD cannot be straightened properly without a certain amount of distortion. Consequently such tubes, while having an average OD and ID within the tolerances shown in this table, require an ovality of tolerance of 1/2% over and under nominal outside diameter, in addition to the tolerances indicated in this table.
