Pipe order for sour service
Standards ：Chinese Standard
Use：Application in environments containing H2S,CO2; Using pure steel production with low content of S and P. Controlling the existence of residual elements and oxidative elements effectively and the content and function of alloy elements reasonable such as Cr, Mo, Ni and etc. It can improve the properties of the pipes, as well as keeping the strength, corrosion resistance, mechanical property, hardness, breaking tenacity, fatigue resistance, weldability and crack characteristics of steel. It can use for the onshore service as well as offshore service.
