Gas pipeline corrosion testing methods1 ScopeThis standard specifies the contents, methods and procedures for testing corrosion outside the buried steel gas pipeline, including general principles, data collection, corrosion location Forecasting, excavation testing, testing cycle determination, recording and reporting, and appendices. This standard applies to short-term anomalies exist in a small amount of liquid water (or other electrolytes) dry gas pipeline. Ground laying gas steel Pipeline corrosion testing may refer to the implementation of this standard.2 Normative referencesThe following documents for the application of this document is essential.
