Global human population growth amounts to around 75 million annually, so providing sanitation and water needs to the world’s mega cities and remote populations means laying pipelines in subterranean and often extreme environments. This can present a number of challenges, from installation access to pipeline durability. With modern pipeline networks expected to perform in excess of 100 years, their performance and durability is coming under increasing scrutiny as any rectifications or leaks in these environments become more costly to fix.
The introduction of mechanised pipe laying has improved installation techniques as it reduces the need for people in the trench, lessening the potential for human error. To continue to improve efficiency, reduce costs and maximize longevity of the network, pipe manufacturers need to give due consideration to concrete pipes joints. Any weaknesses in the joint / seal can result in damage to the pipes, seal displacement and network leakages, resulting in lost time and money associated with pipe scrappage and rectification.
Until the 1960s, most water and sewerage pipe joints were made from horse hair, tarred rope and cement mortar. Being totally rigid, they had no flexibility to allow for ground movement. The introduction of flexible rubber joints enabled more natural movement between pipes without causing damage. Now, the ability to integrate flexible rubber seals within a concrete pipe socket during manufacture is raising standards of leak tightness from infiltration and exfiltration, ease and reliability of jointing, and long term seal durability.
Julian West, Product Manager for Trelleborg’s pipe seals operation in Europe, gives his top tips for specifying integrated concrete pipe seals to extend the life of the asset and infrastructure as a whole.
