Scope
Main technical content: This document specifies the symbols and abbreviations, raw materials, structural types and connection methods, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of nano-ceramic reinforced polypropylene hollow-wall wrapped pipes. This document is applicable to pipes made from nano-ceramic reinforced polypropylene composites as the main raw material using the winding molding process, and composite pipe products formed by combining them with injection-molded plastic end pieces. These products are mainly used in hot-melt butt joint connection of underground or aboveground piping systems.
