T/GDC 362-2026 D-Type UHMF-PP Modified Reinforced Anti-Corrosion Pipe for buried drainage

Scope

This document specifies the terms and definitions, symbols, materials, product classification and marking, pipe structure and connection methods, technical requirements, test methods, inspection rules, marking, transportation, and storage of UHMF-PP modified and reinforced anti-corrosion D-type pipes (hereinafter referred to as pipes) used for underground drainage. This document applies to D-type reinforced anti-corrosion pipes extruded from polypropylene (PP) as the main raw material, with the addition of functional resins and suitable additives. This document is suitable for pipes used for underground drainage, sewage disposal, and farmland irrigation, and can also be used as casings for communication cables. After evaluating the material's chemical resistance and temperature resistance, it can also be used for underground industrial drainage and sewage pipes.
