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.

 

Advantage (compare with seamless cold drawn tube)

Better shape

Improved quality surface

Tight Excentricity and wall thickness tolerances

Good toughness at low temperature

USA Market: 90% of the cylinder in the USA market are produced with welded tubes

Cost fix Lengths More Cheaper
