标准摘要
[中文适用范围]: 本国际标准规定了用于有压或无压供水、灌溉、排水或污水处理系统的以不饱和聚酯树脂(UP)为基础的玻璃增强热固性塑料(GRP)制成的管道系统及其组件的性能。 本国际标准适用于采用顶升技术安装、带有柔性接头的 GRP-UP 管道系统。 它规定了由 GRP-UP 制成的管道的特性,无论有或没有骨料或填料,还规定了本国际标准中提到的测试方法的测试参数。 注:本国际标准中提到的管道,由于其预期用途,要求其最小标称刚度至少为 SN 20000(见 5.2.1)。 本标准适用于尺寸范围为DN100至DN4000、用于在有压或无压情况下输送温度至50℃的水或污水的管道和接头。 它涵盖了证明接头设计的要求,并规定了接头的型式试验性能要求,作为管道系统声明的标称压力等级和系统所需的接头偏转能力的函数。 在本国际标准涵盖的管道系统之间使用的 GRP 配件应符合供水系统的 ISO 10639 或排水和污水处理系统的 ISO 10467(如果适用)。 在管道系统中,不同公称压力和刚度等级的管道可以一起使用。 [外文原描述]: ISO 25780:2011 specifies the properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP) for water supply, irrigation, drainage or sewerage systems with or without pressure. ISO 25780:2011 is applicable to GRP-UP piping systems, with flexible joints, intended to be installed using jacking techniques. It specifies the characteristics of pipes made from GRP-UP, with or without aggregates or fillers and also specifies the test parameters for the test methods referred to in ISO 25780:2011. ISO 25780:2011 is applicable to pipes and joints with a size range from DN100 to DN4000 which are intended to be used for the conveyance of water or sewage at temperatures up to 50 º C, with or without pressure. ISO 25780:2011 covers requirements to improve the design of the joint and specifies type test performance requirements for the joints as a function of the declared nominal pressure rating of the pipeline system and the required joint deflection capability of the system.
