工业应用的塑料管道系统 未增塑聚酰胺（PA-U） 公制系列 用于部件和系统的规范

[中文适用范围]： 本文件规定了用于工业应用中地上和地下热塑性塑料管材及管件的无增塑剂聚酰胺（PA-U）制造的压力管道系统及其组件的特点和要求。 本文件适用于PA-U 管道、配件、阀门及其接头，以及与其他塑料和非塑料材料制成的接头，具体取决于其适用性，用于输送液体、气体流体和含固体物质的流体，用于以下工业应用：—— 输送油、气态燃料和多相混合物（勘探和生产；通用碳氢化合物基流体）；—— 输送可再生气体（氢气、生物甲烷）；—— 输送受污染污水（例如含有碳氢化合物的污水）；—— 输送 CO2 [碳捕获和利用或储存（CCUS）。 [外文原描述]： This document specifies the characteristics and requirements for a piping system and its components, made from unplasticized polyamide (PA-U) intended to be used for thermoplastics piping systems in industrial applications above and below ground. NOTE 1 Requirements applying to industrial valves are given in this document and in other standards. This document is applicable to PA-U pipes, fittings, valves and their joints, and to joints with components of other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following: — transport of oil, gaseous fuels and multiphase mixtures (exploration and production; general purpose hydrocarbon-based fluids); — transport of renewable gases (hydrogen, biomethane); — transport of contaminated sewer (e.g. contaminated with hydrocarbons); — transport of CO 2 [carbon capture and utilisation or storage (CCUS)]. NOTE 2 National regulations can apply. NOTE 3 Other application areas are possible if the requirements of this document and/or applicable national requirements are fulfilled. Characteristics and requirements which are applicable for PA-U are covered by the relevant clauses of this document. Those characteristics and requirements which are dependent on the material are given in the relevant normative Annex A.
