GB/T 18477.3-2009 Unplasticized polyvinyl chloride (PVC-U) structure wall pipeline system for underground soil waste and drainage—Part 3:Bilayer and hollow-wall construction with axial hollow pipes
Abstract
This part of GB/T 18477 specifies the terms and definitions, symbols, materials, classification and marking, structural types and connection methods, technical requirements, test methods, inspection rules and marking, transportation, and storage of hard polyvinyl chloride (PVC-U) double-layered axial hollow-wall pipes (hereinafter referred to as pipes) used for underground drainage, which are extruded from polyvinyl chloride resin (PVC) as the main raw material.
This part is applicable to municipal engineering, outdoor public buildings, and residential areas for underground sewage and drainage, as well as for underground non-pressure farmland drainage pipes.
This part can also be used for industrial sewage and drainage pipes, but in this case, the chemical resistance and temperature resistance of the materials should be taken into account.
