PACIFIC Drawn Over Mandrel (DOM) Tubing is made by electric resistance welding and then cold drawing over a mandrel. This gives the closest tolerances and concentricity available in tubing. DOM Mechanical Tubing is used as raw stock for honed ID hydraulic cylinder barrels and for other mechanical applications requiring accurate dimensional tolerances. It is normally stress relieved after cold drawing. Honed ID DOM is prehoned to exact ID tolerances for standard cylinder sizes. Honed and Chromed ID DOM is intended primarily for use as air cylinder barrels. DOM is most commonly stocked in the AISI 1026 grade; other grades of both carbon and alloy DOM are available in certain sizes. Regular DOM is usually specified by OD and wall thickness. Honed DOM is usually specified by OD and exact ID, i.e., 4" OD X 3.497"/3.500"HID (Honed ID). Custom sizes can be produced and are available in both regular and honed conditions of either carbon or alloy grades.
