Insul-Tek® Ductile Iron System utilizes a tough and corrosion-resistant Ductile Iron carrier pipe conforming to ANSI/AWWA C151/ A21.51. Ductile Iron Pipe offers the advantages of having the physical strengths of mild steel and the longevity of gray iron. Once insulated with our most thermally efficient polyurethane foam and protected with one of our non-corrosive protective casings, this system is an extremely tough and durable alternative to standard steel or plastic piping systems.

Preinsulated Piping Systems, Inc. offers a number of pipe joining systems, including gasketed push-on joint, mechanical joint and victaulic grooved. This system, incorporating one of our spiral lockseam casings of galvanized steel or aluminum, is ideal for above grade applications such as bridge crossings for sewage or potable water lines.
