T/CSTM 00399-2021 The full-scale stress corrosion testing methods for oil pipes and casings
Basic Information
Scope
Scope: This document specifies the terms and definitions, principles, test media, test equipment, samples, test procedures, test results, and test reports for the full-scale stress corrosion performance testing of oil pipes and casings. This document is applicable to the testing of the corrosion resistance and joint sealing performance of actual oil pipes and casings with a simulated specification ranging from Φ 60 mm to Φ 127 mm, which are exposed to corrosive media internally and subjected to axial tensile loads and/or internal pressure at the same time.
