T/CSTM 00173-2019 Joints for composite pipes with enhanced wear-resistant coatings and overlays made of plastic

Scope

Main technical content: This standard specifies the terms and definitions, marking, classification, materials, requirements, test methods, inspection rules, product marking, packaging, transportation, and storage of co-extruded wear-resistant layer reinforced plastic composite pipes and fittings. This standard applies to co-extruded wear-resistant layer reinforced plastic composite pipes and fittings (hereinafter referred to as "composite pipes and fittings") that use polyolefin wear-resistant materials as the wear-resistant layer and employ co-extrusion technology to combine the wear-resistant layer with the reinforced composite pipe. The composite pipes and fittings specified in this standard are suitable for transporting various liquids, slurries, powders, and granular solid media that cause wear and corrosion to the inner wall of the pipeline. The long-term working temperature should not exceed 65℃.
