Thermal Pipe Systems

Heat-Tite®

Pipe size: 1 1/2"-12" diameter, 20' or 40' nominal lengths
Temperature range: 35慚 to 250慚
Max. operating pressure: 150psi
Carrier: Steel
Insulation: Polyurethane foam
Casing: Heavy wall Polyvinyl Chloride (PVC)
Options:

Schedule 40/80 or Standard/Extra Heavy Weight Carrier
Polyisocyanurate foam insulation for extended temperature service
Standard wall PVC or FRP casing

Heat-Tite is a steel piping system featuring a gasketed coupling with built-in expansion control for low temperature hot water, dual temperature, or chilled water service. A FRP casing and polyisocyanurate foam insulation can be substituted when used for high temperature condensate up to temperatures of 300慚 and pressures of 150psi. Heat-Tite meets Federal Guide Specification for condensate and hot water.

Heat-Tite is a top quality, energy efficient piping system that is easy to install. The standard carrier pipe is Schedule 40 A53 steel pipe with the sealing surfaces sand blasted and zinc coated to prevent corrosion. The system is produced with a Ductile Iron double grooved coupling containing high temperature rubber 'V' rings. Insulation is a thermally efficient polyurethane foam with a 'K' factor of 0.14 at 70慚. The heavy wall PVC casing and heat resistant end seals prevent ground water infiltration.

Heat-Tite may be supplied with pre-insulated fittings. Pre-insulated fittings are produced with the same carrier, insulation, casing, and rubber end seals as the pre-insulated straight sections. Fittings may be uninsulated using welded steel or Ductile Iron class 150 fittings with a groove and rubber ring if so specified.

Heat-Tite® Joint

The Heat-Tite joint provides for expansion and contraction through the use of a pre-insulated gasketed coupling. EPDM sealing rings are placed in the groove of the pre-insulated Ductile Iron coupling. The joint compensates for thermal movement without additional stress on the pipe. There is no need for loops or other expansion devices.
