What is the HIC?
Update Time:2018-03-30

Hydrogen induced cracking (HIC) English full name is: Hydrogen induced cracking. Hydrogen sulfide is one of the most corrosive and harmful media in oil and natural gas. In the process of natural gas transmission, the stress corrosion of hydrogen sulfide in the transmission pipeline accounts for a large proportion. When used in a wet hydrogen sulfide environment, hydrogen blistering (HB), hydrogen induced cracking (HIC), and stress induced hydrogen induced cracking (SOHIC) can occur within the carbon steel. In the acidic environment such as hydrogen sulfide contained in the pipe, cracks generated by corrosion-induced hydrogen intrusion into the steel become hydrogen induced cracking (HIC).
