Evaluation of Trenchless Renewal Systems and Techniques for Gas DistributionMains. Final Report, August 1993-March 1995

摘要

The report evaluates promising trenchless technologies for their potential use inrehabilitating or renewing gas distribution pipes. Of the commercially available trenchless renewal options, the U.S. gas industry is primarily using the sliplining method of inserting a new pipe within the old pipe and to some extent pipe bursting. Other trenchless methods have seen little use in the U.S. even though many of these technologies have proven successful and cost-effective for gas utilities have proven successful and cost-effective for gas utilities in Europe and Japan.
