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.
