seamless steel pipe is used 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 Hydro static test,crimping,flared and Squashed test.
quality standard of seamless steel pipe
API 5L Line Pipe for pipeline transportation systems
API 5CT Tubing tubing for wells
API 5CT Casing casing for wells
API 5DP Drill Pipe for well drilling
