PREMIER-PIPE (Sewer Rehabilitation Process)
Premier-Pipe is a C.I.P.P. (Cured in Place Pipe) renovation process, which is installed without the need for costly and disruptive excavation.
Premier-Pipes are individually manufactured to suit the dimensions of the pipes to be lined, the lining thickness being determined by individual design requirements. The lining tube is made of polyester felt with an outer coating of polyurethane, which is impregnated thoroughly with a liquid resin chosen to suit the working environment of the pipe.
Once impregnated with resin the Premier-Pipe is installed using the inversion method described below.
The lead end of the Premier-Pipe is turned inside out for a predetermined length and clamped to a collar over the installation manhole. Water is then introduced into the turned back section creating a head of pressure, which causes the lining to continue turning inside out along the defective pipe. The constant addition of water maintains the head which keeps the lining inverting and ensures it is held firmly against the host pipe.
When the installation is complete the water in the lining is circulated through a mobile water boiler to gradually raise its temperature which achieves a controlled cure of the resin. Once cured, the structural Premier-Pipe lining ends are cut and trimmed.
