标准摘要
[中文适用范围]： 本文件规定了未增塑聚酰胺 (PA-U) 化合物的一般特性，用于制造由这些化合物制成的管道、配件和阀门，用于埋入地下并用于供应气体燃料。它还规定了它所引用的测试方法的测试参数。熔接和/或机械连接。本文件建立了一个计算和设计方案，以此为基础确定 PA-U 管道系统的最大工作压力 (MOP)。注：就本文件而言，术语“气体燃料”包括天然气、甲烷、丁烷、丙烷、氢气、人造气、沼气和这些气体的混合物。 [外文原描述]： This document specifies the general properties of unplasticized polyamide (PA-U) compounds for the manufacture of pipes, fittings and valves made from these compounds, intended to be buried and used for the supply of gaseous fuels. It also specifies the test parameters for the test methods to which it refers. The ISO 16486 series is applicable to PA-U piping systems, the components of which are connected by fusion jointing and/or mechanical jointing. This document establishes a calculation and design scheme on which to base the maximum operating pressure (MOP) of a PA-U piping system. NOTE For the purpose of this document the term gaseous fuels includes, for example, natural gas, methane, butane, propane, hydrogen, manufactured gas, biogas, and mixtures of these gases.
