Honing steel pipes for hydraulic cylinder

High precison cold drawn steel pipe is hot-rolled seamless or longitudinally welded pipesfor the ingredients, squeeze through the mold and processed in the cold-drawn design or plastic deformation precison tubing.This pipe size and high precison, surface roughness, and by deformation enhanced to obtain high strength in the cold plastic deformation process, the yield strength, tensile strength by 20% to 35% than the orginal material.
