Basic Information
Scope
Scope: This document specifies the terms and definitions, symbols, abbreviations, raw materials, pipe classification and marking, pipe structure types and connection methods, technical requirements, test methods, inspection rules and markings, as well as transportation and storage for buried modified polyvinyl chloride (PVET-0M) double-drawn reinforced pipes. The pipes specified in this document are suitable for long-term transportation of media with a temperature below 45°C in buried drainage, sewage and communication sheathing, and power sheathing projects. After evaluating the material's chemical resistance and temperature resistance, they can also be used in buried industrial drainage and sewage pipes. Main technical contents: Terms and definitions, symbols, abbreviations, raw materials, pipe classification and marking, pipe structure types and connection methods, technical requirements, test methods, inspection rules and markings, transportation and storage for buried modified polyvinyl chloride (PVET-0M) double-drawn reinforced pipes.
