GB/T 18477.1-2007 Unplasticized polyvinyl chloride(PVC-U)structure wall pipline system for underground soil waste and drainage—Part 1:Double wall corrugated pipes
Abstract
This part of GB/T 18477 specifies the materials, classification, pipe structure and connection, technical requirements, test methods, inspection rules and marking, transportation, and storage of hard polyvinyl chloride double-wall corrugated pipes (hereinafter referred to as "pipes") for underground drainage, which are extruded from polyvinyl chloride resin as the main raw material. This part is applicable to non-pressure municipal underground drainage, building external drainage, and farmland drainage pipes, and can also be used as sheathing pipes for communication cables. Considering the chemical resistance and temperature resistance of the materials, they can also be used for non-pressure underground industrial sewage pipes.
