This paper discusses the thermally butt-fused PVC pipe (FPVCP) technology that is enabling trenchless growth and highlights two cases studies where FPVCP was utilized based specifically on its material
properties; a 3,800 foot (1,1140m) HDD installation with 24-inch (600mm) and 6-inch (150mm)
pipe pulled in simultaneously under a live airport runway in Portland, Oregon and a water utility
in Colorado that has installed over 150,000 feet (45,000m) of FPVCP via the pipe-bursting
NEW PAPER - PVC - REVIEW OF AVAILABLE TECHNOLOGIES FOR TRENCHLESS PIPELINE APPLICATIONS
Nigel Jones, Australian Vinyls
While open-cut installations continue to be the standard method of construction for new projects where access is readily available, for projects in developed urban areas various PVC trenchless technologies are making no dig options more economically viable and appealing. For rehabilitation of our cities aging pipelines, PVC trenchless technologies make it possible to restore the structural integrity and fluid velocity of the pipeline whilst minimising the financial and social costs. In this paper, the options for and advantages of PVC in common trenchless installation techniques are reviewed.
Trenchless technology has the advantage of minimising or eliminating excavations, with the installation of new pipelines being completed using pre-drilled holes, or by bursting an existing pipeline or relining using a close fitting liner. Trenchless technology also makes it possible to rehabilitate aging pipelines without digging up the entire pipe system, restoring both the structural integrity and improving the pipeline fluid velocity, thus greatly minimising the social costs associated with the disruption to traffic, pedestrians, businesses and customers.
