Analytical Testing of Advanced Butt Fusion Technology for HDPE Pipe [PE]

 

Plastic Pipes Conference Association # 2006 Washington DC

Sandstrum, McKinley

The market for high density polyethylene (HDPE) pipe continues to expand across a variety of end use applications. As this growth continues to accelerate, users within the market place have become more familiar with the traditional method of joining HDPE pipe, namely butt fusion, and have become more educated in the benefits, challenges and potential impact this joining method may have on project economics. In recent years, however, advancements in butt fusion technology have paved the way for improved efficiencies in the joining of HDPE pipe. This paper will focus on one of these advancements which has recently been introduced to the North American market and has become known as automated mobile fusion technology. The discussion which follows explains the technology associated with this joining technique and presents the analytical testing undertaken to verify the integrity of HDPE pipe joints made with this adaptation of the butt fusion procedure. The discussion shall conclude with example comparisons of the improvements in job site efficiency achieved with this technology as compared to the conventional butt fusion joining process.
