英国的水工业是根据其维持地下水源的方式来评判的 以足够的压力输送足够数量的优质水。实际上 这涉及修复旧铸铁水管，该行业目前正朝着 使用更便宜的薄壁聚乙烯（PE）互动衬里，共享内部 主管道的压力负荷。PE在长期蠕变和颈缩方面存在局限性 桥接空隙、缝隙和内部突出物。本文介绍了一系列已开发的硅烷交联聚乙烯（SPEX）衬里 专门用作互动衬里。衬里可以作为松套式PE管安装， 然后用流动的饮用水原位交联，产生完全交联的聚合物 结构具有优异的长期蠕变、屈服应变和抗裂性。这种 PE-X衬里也可以使用标准PE设备进行对接熔焊和挤压。包括14个参考文献、表格和图表。

The water industry in the United Kingdom is being judged on the way that it maintains its underground assets to deliver a sufficient quantity of good quality water at an adequate pressure. In practice this involves rehabilitating the old cast iron mains and the industry is now moving towards using less expensive thin wall polyethylene (PE) interactive linings, which share the internal pressure loads with the host pipe. PE has limitations in long term creep and necking when bridging voids, gaps and internal protrusions. This paper describes a range of Silane cross-linked PE (SPEX) liners that have been developed specifically for use as interactive linings. The liners can be installed as a loose fitting PE pipe, then cross-linked in-situ using the flowing drinking water to produce a fully cross-linked structure having superior long term creep, yield strain and crack resistance to PE. This type of PE-X liner can also be butt fusion welded and extruded using standard PE equipment. Includes 14 references, table, figures.
