Detailed Description

DOM steel tube Specifications:1) Heat treatment: stress relieved, normalized, or cold finished .2) Standards: ASTM A513 3) Continuous stenciling as per requirement 4) Rust prevention treatment, oiled 5) Plastic plugs in both ends 6) Hexagonal bundles of max. 2,000kg with several steel strips 7) Smooth surface, uniform mechanical property, indiscernible welded line, tight toleranceInner packing:Two tags on each bundleOuter packing:Wrapped in waterproof paper, PVC sleeve, and sackcloth with several steel stripsOne tag tied on the outer packageHeavy Tri-wall boxes, wooden boxes, slats or frames if client required Certain applications require closer tolerances on O.D., wall thickness and I.D. than are available in off-the-mill welded tubing. Metal-Matic's Drawn Over Mandrel (DOM) tubing also possesses the higher mechancial properties achieved in cold drawing to these tighter standards. After normalizing, the tubing is cold drawn through a die and over a mandrel to reduce diameter and wall thickness to required dimensions. Special smooth I.D. surfaces are available for critical applications such as hydraulic cylinders and shock absorbers. Statistical process control is used to reduce variations in dimensional and other characteristics and is one of the tools used in our drive for continuous improvement. Our exacting quality control testing completes the process.
