scope:

The program undertaken by the MAB Task Group combined common installation practices shared by multiple manufacturers into a single format. The goal is to provide clear direction and common procedures for proper pipe preparation, fitting-to-pipe assembly, and installation of electrofusion fittings on 12 inch or smaller pipe. An additional goal is to provide clear inspection criteria for installer qualification, installation acceptance by inspection, and answers to frequently asked questions. For installation of larger electrofusion couplings, the user can reference MAB-2 MAB Generic Electrofusion Procedure for Field Joining of 14 Inch to 30 Inch Polyethylene (PE) Pipe. For sizes greater than 30 inches, refer to the manufacturer.

The Municipal Advisory Board hopes that the inherent value of greater uniformity will provide all the incentive necessary for companies to evaluate the procedure as a first option for electrofusion joining of its PE piping products. Use of this procedure is obviously not mandatory, and every electrofusion fitting producer, equipment manufacturer, and water system operator retains the option of developing different procedures for its particular products and pipelines. However, MAB believes that its work in developing this procedure as a candidate for widespread acceptance throughout the industry will lead to greater efficiency, simplicity, and understanding in this area and promote the use of effective, qualified procedures for electrofusion joining of PE pipe.
