T/GDC 66-2020 Modified Polyvinyl Chloride (PVET-OM) Double-Stretch Biaxial Strengthened Pipe for Burial Use
Basic Information
Scope
Scope: This standard 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, transportation and storage for modified polyvinyl chloride (PVET-0M) double-pull reinforced pipes used in underground applications. The pipes specified in this standard are suitable for long-term conveying of media with a temperature below 45°C in underground drainage, sewage disposal, and communication and power shielding projects. After evaluating the chemical resistance and temperature resistance of the materials, they can also be used in underground industrial drainage and sewage pipes. Main technical contents: color, appearance, specifications and dimensions, physical and mechanical properties, and system applicability.
