Thermal Pipe Systems, Inc. DUC-TITE® Rugged Ductile Iron Gasketed Piping System For Low Temperature Hot Water and/or Chilled Water Service Duc-Tite is energy efficient piping system that is easy to install. It is used in hot water service to 250ºF at pressures to 150psi. I may be used at higher pressures for chilled water. The carrier pipe is Class 51 for 3” & 4” and Class 50 for 6” through 20” ductile iron pipe. Insulation is a thermally efficient polyurethane foam with a ‘K’ factor of 0.16 at 70ºF. The heavy wall PVC or HDPE casing and heavy-duty compression end seals prevent ground water infiltration. To join Duc-Tite, lubricate the spigot end and push it home into the bell. The joint compensates for thermal movement without additional stress on the pipe. There is no need for loops or other expansion devices. In the field the system is easily adaptable to other materials with commercially available fittings. Rubber ring ‘push-on’ type fittings make changes in direction simple. This product combines the high strength of ductile iron with the efficiency of polyurethane foam to create an excellent choice for underground distribution systems. TECHNICAL DATA DUC-TITE® PIPE
