10、egas distribution systems,which typically operate at less than 1psig,MPL CIP liners are not intended for use as a stand-alonegas carrier pipe but rely on the structural integrity of the hostpipe.Therefore,the safe use of cured-in-place pipe liningtechnology for the rehabilitation of existing cast ir
