What is Sour Service Pipe and differences with Normal Pipes
C and carbon equivalent: With the mass fraction of carbon increases, the HIC sensitivity increases. The reduction of carbon and carbon equivalent can improve the H2S corrosion resistance of pipeline steel. And it will generate the harmful martensite formulas, which is very sensitive to H bubbles for the hot rolled steel. 2). P element for sour pipe
