Abstract:
A pipe liner and a method of using the same are provided. The method includes inserting a pipe liner impregnated with a resinous material into a length of pipe, where the pipe liner has an outer diameter substantially equal to or greater than an inner diameter of the pipe. A bladder having an unstretched outer diameter less than the inner diameter of at least a portion of the length of pipe and capable of stretching circumferentially is inserted into the pipe liner. The bladder is expanded under fluid pressure against the pipe liner, pressing the pipe liner against an inner wall of the length of pipe. The resinous material is allowed to cure and harden, leaving a renewed pipe wall. The length of pipe may have a plurality of inner diameters, and the bladder stretches to produce a smooth interior surface of the pipe liner across the plurality of pipe diameters.
