Insul-Tek® Dual-Con System
Typical Uses:
Steam and Condensate Distribution
District Heating and Cooling
High-Temperature Hot Water
Cogeneration
Process Fluids
Drainable, Dryable, Air Testable, Class “A”
Steel Conduit system utilizing a non-corrosive
High-Density Polyethylene (H.D.P.E.) Exterior Casing
Insul-Tek® Dual-Con is the ideal system for use on those sites that pose the most difficult of conditions for an underground preinsulated piping system. The Dual-Con system provides “double protection” for your underground piping systems.
The Dual-Con system utilizes two (2) separate protective casings. The Exterior Casing is a Corrosion Proof, non-metallic High-Density Polyethylene (H.D.P.E.) casing, which is one of the toughest and most durable materials available today.
The Inner Casing is a Steel Conduit which provides the strength of steel and is easily welded in the field and air tested to prove its integrity (tightness). Dual-Con utilizes Two (2) different types of Insulation Systems, an Exterior Layer of the most thermally efficient Polyurethane Foam insulation, in conjunction with an Inner Layer of High-Temperature Insulation consisting of mineral wool, Foamglas®, calcium silicate or perlite insulation.
Insul-Tek® Dual-Con is manufactured to withstand the most severe and corrosive conditions that can be found in an underground heat distribution site. Dual-Con is both the most thermally efficient system and the most corrosion resistant preinsulated piping system available today.
