T/JCJJ 032-2024 Continuous Fiber Wound Reinforced Polyethylene Composite Pipe (CWPP-PE)

Scope

Scope: This document specifies the terms and definitions, principles, and product process reports for the evaluation of continuous fiber-wound reinforced polyethylene composite pipes in the building materials industry. This document is applicable to the production guidance of continuous fiber-wound reinforced polyethylene composite pipes in the building materials industry. Main technical contents: This document specifies the terms, definitions, symbols, abbreviations, classification and marking, structural dimensions and connection methods, materials, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of continuous fiber-wound reinforced polyethylene composite pipes (CWPP-PE). This document is applicable to water with a temperature not exceeding 40°C and a working pressure not exceeding 6.4MPa, used for water transmission and distribution, domestic drinking water, buried fire-fighting pipes, and mining pressure pipes, industrial cooling water circulation, and medium-high pressure oil and gas pipelines. Taking into account factors such as the material's chemical resistance and temperature resistance, it is also applicable to composite pipes used for sewage transportation, seawater transportation, and brine transportation in the salt chemical industry.
