压力和非压力供水、排水或污水处理用塑料管道系统.基于不饱和聚酯（UP）树脂的玻璃增强热固性塑料（GRP）系统

[中文适用范围]： 本文件规定了由基于不饱和聚酯树脂（UP）的玻璃增强热固性塑料（GRP）制成的管道系统组件的性能。 它适用于所有类型的有压或无压供水、排水和污水处理。 供水类型包括但不限于原水、灌溉水、冷却水、饮用水、盐水、海水、发电厂、加工厂和其他水基应用中的压力钢管。 本文件适用于 GRP UP 管道系统，具有柔性或刚性接头，具有或不具有端部推力承载能力，主要用于直埋安装。 注 1：就本文件而言，术语聚酯树脂（UP）还包括乙烯基酯树脂（VE）。 注 3 管道。 本文件也可适用于其他安装，例如现有滑衬修复。 注 2：符合本文件的管道系统也可用于非埋地应用，只要在设计时考虑环境和支撑的影响。 管道、配件和接头。 注 4 规定了用于顶进安装的 GRP 管道的要求。 参考本文件的管道静水压设计要求符合ISO/TS 20656-1的要求和设计实践中详细说明的结构可靠性一般原则，并解决了失效概率以及失效可能产生的后果。 设计实践基于部分安全系数概念以及风险管理工程。 本文件适用于公称尺寸为 DN 50 至 DN 4000 的圆形管道、配件及其接头，这些管道、配件及其接头旨在用于在正常使用条件下（带压或不带压）输送水、污水和排水。 [外文原描述]： This document specifies the properties of piping system components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP). It is suited for all types of water supply, drainage and sewerage with or without pressure. Types of water supply include, but are not limited to, raw water, irrigation, cooling water, potable water, salt water, sea water, penstocks in power plants, processing plants and other water-based applications. This document is applicable to GRP UP piping systems, with flexible or rigid joints with or without end thrust load-bearing capability, primarily intended for use in direct buried installations. NOTE 1 For the purpose of this document, the term polyester resin (UP) also includes vinyl-ester resins (VE). NOTE 2 Piping systems conforming to this document can also be used for non-buried applications, provided the influence of the environment and the supports are considered in the design of the pipes, fittings and joints. NOTE 3 This document can also apply for other installations, such as slip-lining rehabilitation of existing pipes. NOTE 4 ISO 10467 and ISO 10639, which are replaced by this document, are also referenced in ISO 25780, which specifies requirements for GRP-pipes used for jacking installation. The requirements for the hydrostatic pressure design of pipes referring to this document meet the requirements of ISO/TS 20656-1 and the general principle for the reliability of structures detailed in ISO 2394 and in EN 1990. These International Standards provide procedures for the harmonization of design practices and address the probability of failure, as well as possible consequences of failures. The design practices are based on a partial safety factor concept, as well as on risk management engineering. This document is applicable to circular pipes, fittings and their joints of nominal sizes from DN 50 to DN 4000, which are intended to be used for the conveyance of water, sewage and drainage at normal service conditions, with or without pressure.
