Insul-Tek® Dual-Con Preinsulated
Piping System
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.
