Maintaining urban gas systems demands special technologies. T.F. Anglero. Pipeline Gas J., April 1994, 221(4), 37--39.
Innovative trenchless technology is used to repair a gas main in Brooklyn. The Tite Liner system for installing a polyethylene liner inside a 20 in. steel main operating at 15 psi is described. The liner pipe is radially compressed by about 7% and a pulley winch maintains the reduced diameter during insertion. The installation procedure is described and the lined main is hydrostatically pressure-tested in accordance with Federal safety standards. Throughput capacity is not reduced, significant cost-savings are achieved in construction time and excavations, and traffic disruption is minimized in a busy urban area. Several new pipe-lining techniques of this type are being investigated by utility operators and by the Gas Research Institute.
