Abstract
A method for installing plastic liners in pipes includes the steps of providing a plurality of cylindrical tubular liners of plastic material of predetermined diameters. Ribs extend radially between the liners. The liners are deformed or collapsed to reduced overall diameters. The liners are introduced into the pipe. The cylindrical shapes of the liners in the pipe are then restored with the ribs spacing the liners one from the other.
