Product Description

Product Description

 seamless steel pipes 

Our seamless steel pipes are produced by advanced hot rolling and cold drawing technologies. There is no welding seam on the pipe body, which effectively guarantees overall structural integrity, pressure resistance and safety.We offer a full range of products including carbon steel, alloy steel and heat-resistant steel seamless pipes, covering common grades such as 20#, 45#, Q355B, 15CrMoA, 12Cr1MoV, F11, F22, F91 etc. All products comply with international standards like GB, ASTM, JIS, DIN and EN.

Each batch is accompanied with official Mill Test Certificate, and we conduct strict dimensional inspection, hardness test and non-destructive testing (NDT) before delivery. We can provide cutting, finishing and customized processing services to meet diverse customer requirements. Our products are exported to many countries and regions, well received by clients for reliable quality and competitive price.
