Generic electro fusion procedures developed by the plastic pipe institute - Municipal advisory board

 

Papers # 2016 Berlin

The Plastic Pipe Institute Municipal Advisory Board recently completed the publishing of the “Generic Electro Fusion Procedure” covering 12 inch and smaller sizes. This publishing effort was conducted with a collaboration of water system operators and electro fusion fitting manufacturers specifically addressing concerns raised by the water operators. The following paper details the organizations responsible, steps taken and covers a few key elements of this document.

The successful performance of high density polyethylene (HDPE 4710/PE100) water distribution systems fabricated with electro fusion fittings requires consistent installation procedures. Several water system operators/owners tasked the Municipal Advisory Board (MAB) to develop installation guidelines specifically addressing electrofusion fittings due to premature failure associated with improper installation of these fittings. Two international electrofusion fitting manufacturers worked with MAB utility members to develop generic procedures which were published in late 2015. This presentation will cover the steps taken during the development of this document, which was ultimately accepted by all electrofusion manufacturers supplying the North American water market, including a review of the specific topics included.
