GB/T 43005-2023 Composite pipes of polyethylene reinforced with continuous wound glass-fiber-tape for water supply 1 Scope This document specifies the materials, pressure reduction factor, structure and connection mode, requirements, test methods, inspection rules, marking, packaging, transportation and storage of composite pipes of polyethylene reinforced with continuous wound glass-fiber-tape for water supply (hereinafter referred to as "composite pipes"). This document is applicable to the composite pipes, with water temperature not higher than 40°C, for general purpose pressure water transmission and drinking water transmission and distribution. Considering the influence factors such as chemical resistance and temperature resistance of the materials, it is also applicable to the composite pipes for sewage transportation, seawater transportation and brine transportation in the salt chemical industry. Note: It is the responsibility of the purchaser to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and standards or codes. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document.
