Abstract: This paper reviews the developments over the past fifteen years in a factory insulated high density polyethylene piping system that has become a standard for sewage and water piping systems in Arctic regions of North America. The history of Arctic sewage and water systems is reviewed and the features and benefits of the factory insulated piping systems which have led to its introduction and widespread use are discussed. This paper provides an understanding of the components of a factory insulated high density polyethylene (HDPE) piping system including pipe, pipe insulation, insulation jacketing, fittings, and fittings insulation, and electrical heating systems.
