February 13, 2017
Seamless pipe lineissued for the mechanical structure, hydraulic equipment ,which is have precision size ,good surface finish.It can greatly reduce mechanical processing hour and improve material utilization, and to improve the quality of products. High quality of cold draw seamless pipe line are mainly use the 10# 20#.In addition to ensure chemical composition and mechanical properties,it will check by Hydrostatic test,crimping,flared and Squashed test.
