The MAB Generic Electrofusion Procedure for Field Joining of 12 Inch and Smaller Polyethylene (PE) Pipe (MAB-01-2022) guide has been updated by the Municipal Advisory Board (MAB) and is available as a free download from the MAB website. The updates focus on HDPE water piping systems that include new sections on electrofusion, safety and cleaning; the new requirement to use a minimum of 90% isopropyl alcohol; new tables on peel depth and cooling times for couplers and saddle fittings; improved questions in the sample test; emphasis on the use of peelers (instead of scrapers) in most locations; plus, new inspection checklists have been added.
MAB serves as an independent, non-commercial adviser to the Municipal & Industrial Division of the Plastics Pipe Institute, Inc. (PPI), the North American trade association representing all segments of the plastic pipe industry.
