ISO 25780:2011 标准是针对玻璃纤维增强热固性塑料管道系统的插接式柔性接头的标准。这些接头适用于使用顶管技术安装的管道系统，包括压力和非压力供水、灌溉、排水或污水处理。

该标准规定了插接式柔性接头的要求，包括接头的尺寸、材料、性能和测试方法。此外，该标准还规定了接头的安装要求，包括接头的安装方法、接头与管道的连接方式以及接头的密封性能。

在使用顶管技术安装管道系统时，插接式柔性接头是非常重要的。这种接头可以在管道安装过程中承受一定的变形和位移，从而保证管道系统的连续性和完整性。此外，插接式柔性接头还可以减少管道系统的应力和振动，从而延长管道的使用寿命。

总之，ISO 25780:2011 标准为玻璃纤维增强热固性塑料管道系统的插接式柔性接头提供了详细的规定和要求，这些规定和要求可以保证管道系统的安全、可靠和持久。
