General information of seamless steel pipe for sour service


The billet for seamless steel pipe for sour service adopt pure, fully killed, fine grain steel. The content of sulphur, phosphor and other harmful elements is strictly controlled. Meanwhile elements Nb, V, Al and other alloy elements have been added. The seamless steel pipe has not only high resistance against H2S, but also have better performance of mechanical properties, hardness, breaking toughness, fatigue resistance and crack prevention ability. The test result of SSC (NACE TM0177) and HIC (NACE TM0284) have reached the requirements of API 5L after the inspection of competent authorities. This kind of pipe can fully meet the demand of NACE MR0175 or ISO 15156
