Degradation of the tubing metal in hydrogen-sulfide environments

We analyze damages in tubing metal of domestic (D steel) and foreign (C-95 steel) production and also determine the coefficients of degradation of the metal after long-term exploitation. It is shown that the tubing metal of C- 95 steel is subject to general corrosion, hydrogen-induced cracking, and...

Description
Summary:We analyze damages in tubing metal of domestic (D steel) and foreign (C-95 steel) production and also determine the coefficients of degradation of the metal after long-term exploitation. It is shown that the tubing metal of C- 95 steel is subject to general corrosion, hydrogen-induced cracking, and hydrogen-sulfide stress corrosion cracking even under the conditions of inhibition. Tubing metal of D steel was not subject to hydrogen-sulfide stress corrosion cracking even after eleven years of exploitation. It is established that degradation of D steel is lower than that of C95 steel.
