Advantage of D.O.M.

1. D.O.M. tubes are produced from hot rolled or cold rolled strips as raw materials and have better eccentricity than seamless tubes, and its uniform roundness after cold drawing makes machining easy and save cost.

2. Tubes sre finished more accurately in size and better condition on innner surface after cold drawing, which result in saving process time of horning operation.

3. Mechanical properties of D.O.M. tubes are equal to those of seamless tubes.
