E235 EN10305-2 WT15 Straight Mild Cold Drawn Welded Tubes With Good Mechanical Properties
Introduction
Cold drawn welded pipe, it is the production of one of the best choice of the multistage hydraulic cylinder tube, its process and precision seamless steel tube cold drawing process, is to use precision resistance welding (ERW) precision drawing, manufacturing the EN 10305-2 eu mechanical cold drawn steel tube welding standard.
After welding of resistance welded pipe, the overall pipe body passes through the positive fire to ensure that the weld and heat affected zone are in the same quality as the other parts in the metallographic structure and mechanical properties; Cold drawing and subsequent heat treatment (eliminating internal stress) and steel pipe have good size and mechanical properties.
