T/CSTM 00400-2021 The method for corrosion testing of petroleum pipe materials in environments containing hydrogen sulfide and oxygen
Basic Information
Scope
Scope: This document specifies the terms and definitions, test principles, test solutions, test gases, test containers and devices, sample requirements, corrosion weight loss tests, sulfide stress cracking tests, result evaluation, and test reports for sulfur-resistant oil pipes in environments with hydrogen sulfide and oxygen injection. This document is applicable to the selection and suitability evaluation of sulfur-resistant oil pipes in environments with oxygen-acidic injection, involving carbon steel, low-alloy steel, and stainless steel transmission pipes used in gas collection stations and gas injection well sites, as well as downhole carbon steel, low-alloy steel, and stainless steel oil pipes, casings, and drilling tools. This document is not applicable to the selection and suitability evaluation of oil pipes in environments with CO2 injection.
