Thermal Pipe Systems, Inc. HEAT-TITE® Steel Piping System Featuring Gasketed Coupling with Built-In Expansion Control For Low Temperature Hot Water and Dual Temperature Service Heat-Tite is energy efficient piping system that is easy to install. It is used in hot water service to 250ºF at pressures to 150psi. The standard carrier pipe is schedule 40, A-53 steel pipe the sealing surface protected to prevent corrosion. The system is produced with a Ductile Iron double grooved coupling containing high temperature rubber ‘V’ rings. Insulation is thermally efficient polyurethane foam with a ‘K’ factor of 0.16 at 70ºF. The heavy wall PVC or HDPE casing and heat resistant end seals keep the insulation dry. Pre-insulated fittings are available. To join Heat-Tite, simply push the spigot end into the coupling. A lubricant is supplied for ease of installation. The rubber ring joint compensates for thermal movement without additional stress on the pipe. There is no need for loops or other expansion devices. The coupling is factory pre-insulated to further expedite installation. Heat-Tite meets Federal Guide Specifications for condensate and hot water. TECHNICAL DATA HEAT-TITE® PIPE
