CIPP systems create a close-fit `pipe-within-a-pipe’ which has quantifiable structural strength and can be designed to suit various loading conditions. As well as minimising bore reduction, an inherent advantage of cured-in-place liners is their ability to conform to almost any shape of pipe, making them suitable for relining non-circular cross-sections.
In the systems offered by APS, the common feature is the use of a fabric tube impregnated with polyester, vinylester or epoxy resin. The tube is inserted into the existing pipeline and inflated against the pipe wall. It is then cured by re-circulating hot water or steam, or by applying ultra-violet light.
The two systems offered by APS have different characteristics which make them particularly suitable for different uses. Further information on all these products offered by APS is contained in the products section of this website.
