Introduction
The content of this document is aimed at the needs of plastic pipe systems for water supply and heating in my country, combined with the plastics currently used in plastic pipe systems.
Plastic valves, especially those used in hot water pipe systems, are limited by the strength of plastics.
At present, only ball valves have application cases in terms of structure, so the content of this document only involves ball valves. Other structural valves are subject to technical development.
After it is mature and has certain engineering use experience, it will be supplemented and improved in a timely manner.
GB/T 28799 "Heat-resistant Polyethylene (PE-RT) Pipe Systems for Hot and Cold Water" is based on the actual production and application of plastic pipe products in my country.
The grass is planned to consist of the following five parts.
--- Part 1.General. The purpose is to establish the terms, definitions,
Symbols and abbreviations, levels of conditions of use, material requirements.
--- Part 2.Pipes. The purpose is to establish materials, product classification,
Selection, requirements, system suitability, test methods, inspection rules, marking, packaging, transportation and storage of pipe series S.
--- Part 3.Pipe fittings. The purpose is to establish materials, product classification,
Requirements, system suitability, test methods, inspection rules, marking, packaging, transportation and storage.
--- Part 4.Valves. The purpose is to establish the materials, model compilation,
Requirements, system suitability, test methods, inspection rules, marking, packaging, transportation and storage.
--- Part 5.System suitability. The purpose is to establish the suitability of heat-resistant polyethylene (PE-RT) piping systems for hot and cold water.
Requirements and test methods.
The use pressure of the valves specified in this document at different temperatures shall be selected with reference to the use conditions of the pipes, fittings and connection systems.
Use, such as S level.
The performance requirements and test verification specified in this document are based on ball valves produced from heat-resistant polyethylene (PE-RTⅡ) materials.
Polyethylene (PE-RTⅠ) materials need further verification of relevant performance and requirements, considering compatibility and system applicability.
Heat-resistant polyethylene (PE-RT) piping systems for hot and cold water
Part 4.Valves
1 Scope
This document specifies the materials, classifications, models, specifications, dimensions, deviations and
The requirements for physical and mechanical properties, inspection rules, marking, packaging, transportation and storage are described, and the corresponding test methods are described.
This document is applicable to the manufacture and inspection of ball valves made of PE-RTⅡ material with a nominal size not exceeding 400mm.
