Scope

Main technical content: This document specifies the general requirements for small-diameter steel pipes, data collection, defect characterization and damage pattern recognition, pipeline inspection, fitness-for-service evaluation, defect repair, and recordkeeping and reporting. The fitness-for-service evaluation method provided in this document provides technical support for safety management decisions for small-diameter steel pipes. This document is applicable to carbon steel pipes used for transporting oil and gas media, with operating temperatures ranging from -45°C to 100°C, operating pressures between 0.1 MPa and 10 MPa, and nominal diameters not exceeding 50 mm. For pipes made of other materials or with different media temperatures or pressures, they can be used as a reference for reference.
