T/JXHXHG JXHG001-2019 FRPE Double-Plastic Composite Structure Wall Pipe

Scope

Scope: This standard specifies the terms and definitions, symbols, materials, classification and marking, structure and connection methods, requirements, test methods, inspection rules and markings, transportation and storage of FRPE double-plastic composite wall pipes. This standard applies to drainage pipes and fittings for long-term conveying of media with temperatures below 45℃, including urban drainage, industrial drainage, and agricultural drainage. Main technical content: This standard specifies the terms and definitions, symbols, materials, classification and marking, structure and connection methods, requirements, test methods, inspection rules and markings, transportation and storage of FRPE double-plastic composite wall pipes. This standard applies to drainage pipes for long-term conveying of media with temperatures below 45℃, including urban drainage, industrial drainage, and agricultural drainage. FRPE double-plastic composite wall pipes are made from polyethylene (PE) as the main pipe material and fiber-reinforced polypropylene (FRPP) composite material as the auxiliary supporting material, using a multi-layer co-extrusion extrusion process to form the pipes. The construction and connection methods of FRPE double-plastic composite wall pipes include electric heat fusion socket and single seal water-swellable rubber ring socket. Electric heat fusion socket: no pipe fittings are used, and a precision injection molding one-time forming socket expansion process is adopted, with heating electric fusion copper wires installed internally for one-time forming connection. Single seal water-swellable rubber ring socket: no pipe fittings are used, and an injection molding socket expansion process is adopted, with a double-peak water-swellable rubber ring installed internally.
