Research Progress on Pipeline Steel Used for Oil and Gas Transmission in Acid Environment

The oil and gas fields which containing H2S have been rapidly developed,thus the development of pipeline steel used for oil and gas transmission in acid environment is imperative.The research progress of the pipeline steel used for oil and gas transmission is reviewed from the mechanism of the H2S corrosion and the influencing factors under the service condition in acid environment.At the same time the current development of the acid corrosioin resistance steel pipe used for the oil and gas transmission at home and abroad is introduced. The sulfide stress corrosion cracking(SSCC) resistance study of the pipeline steel is pointed out and the related standards should be further investigated.
