Sour service Line Pipe

Sour service Line Pipe

Sour Resistance Line Pipe series are able to used in the environment containing H2S, CO2, H2S+CO2 and chlorine ion and other corrosion medium. This type of acid resistance line pipe have a higher performance requirements than normal type of line pipe. It has good anti corrosion ability, mechanical performance, hardness, break toughness, fatigue resistance, weld nature, crack prevention ability. Therefore, it not only can be used as the land transmission pipe line, but also as the sea bed transmission pipe lines.

The Acid Resistance Line Pipe are produced from the purified steel, it have very low sulphur, phosphor. The acid resistance line pipe have effectively controlled the residual elements the Cr, Mo, Ni and other alloy elements content are added in the steel to guarantee the toughness of the steel while improving the quench penetrating characteristics and other performances. The control to the crack sensitivity coefficient and carbon equivalent have been controlled strongly for this pipe, so as to prevent the occurrence of the welding cold cracks, therefore it have very good welding ability.
