Description:
In order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold usually in two roller mill, rolling ring groove tapered plug pipe in variable cross section circular slot and the composition of the. Cold drawing was usually in the 0.5 ~ 100T single chain or double chain drawbench.

The mechanical properties of steel is an important index to ensure the final use of steel (mechanical properties), it depends on the chemical composition and heat treatment system. In the steel pipe standard, according to the different requirements, the tensile properties (tensile strength, yield strength, yield strength, elongation) and hardness, toughness index, as well as high and low temperature performance, etc..
