GB/T 43005-2023Composite pipes of polyethylene reinforced with continuous wound glass-fiber-tape for water supply (English PDF)

1 Scope

This document specifies the materials and pressure reduction systems of reinforced polyethylene composite pipes (hereinafter referred to as "composite pipes") wound with continuous fiberglass tape for water supply.

Number, structure and connection method, requirements, test methods, inspection rules, marking, packaging, transportation and storage.

This document is applicable to composite pipes for general purpose pressure water transmission and drinking water transmission and distribution where the water temperature is not higher than 40°C. Thinking about it

In the case of factors such as chemical resistance and temperature resistance of the material, it is also suitable for sewage transportation, seawater transportation and brine transportation in the salt chemical industry.

Use composite pipes.

Note. The purchaser is responsible for the appropriate selection of this product based on its specific application needs and in conjunction with relevant regulations, standards or specifications.
