Thermally Fused PVC Pipe Helps Accelerate Adoption of Trenchless Pipe Installation Techniques in North America

 

Tom Marti, Richard (Bo) Botteicher

Papers # 2014 Chicago

In North America, trenchless pipe installation methods continue to see rapid adoption in municipal markets with well over 70 percent of utilities having used some form of trenchless methods in the recent past according to a 2012 survey. This adoption rate is a function of improving equipment, installation experience, improved materials, and seasoned installers. 

The three most recognized trenchless installation methods for pressure pipe; horizontal directional drilling (HDD), sliplining and pipe-bursting are seeing rapid growth in application. Improvements in methods and materials have stretched the boundaries of these technologies, allowing longer lengths of pipe, larger sizes and an increased range of project constraints to be managed. Pipe joining methodologies for thermoplastic pipe materials and specifically the increasing use of thermally butt-fused PVC pipe (FPVCP) (over 1,500 miles or 2,400 km in service) have had the largest impacts on the growth of these installation modes in North American water and wastewater infrastructure. 

This paper discusses the 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 method.
