    2. Precision cold drawing and cold pumping equipment: drawing machine (pipe pulling machine, cold drawing machine, core pulling machine, pipe pulling machine), straightening machine (straightening machine),. Shrink head machine (shrink mouth machine), pull flower machine.

    3 .Adjusting the speed of the straightener is operated according to the bending degree and material of the steel pipe. There are usually the following cases, the greater and harder the bending degree, and the slower the speed, the faster the opposite. In order to make the angle of straightening roll can have good contact, the surface principle of steel pipe and roller must be guaranteed.
