Cured-in-Place Pipe is a resin-impregnated, flexible fabric tube which is pulled into its place of installation and inflated. The resin is cured by circulating hot water or by the introduction of controlled steam into the tube. When cured, the finished CIPP pipe will be continuous and tight fitting. This process can be used in a variety of gravity and pressure applications such as sanitary sewers, storm sewers, process piping, electrical conduits and ventilations systems.
Since its early adoption of the technique, Eckard Brandes Inc. lined thousands of feet of pipe with CIPP, in diameters ranging from 8 to 54 inch. CIPP systems create a close-fit ‘pipe-within-a-pipe’ which has quantifiable structural strength and can be designed to suit various loading conditions. The ring-stiffness of the liner is enhanced by the restraint provided by the host pipe and the surrounding ground. Most CIPP systems require flow diversion during installation and cure.
CIPP is versatile, able to accommodate non-circular sections, bends, changes of cross section, all pipe materials and various loading conditions. It produces a close-fit liner with a smooth internal surface, and the low hydraulic roughness often compensates for the reduction in bore. The liners generally used are resistant to all chemicals normally found in sewers.
