Super Temp-Tite® is a pre-insulated piping system for conveying high pressure steam underground. It may be used in steam distribution at temperatures to 400ºF and pressures to 250 psi. The standard carrier pipe is schedule 40, ASTM A-53 steel pipe. Other grades of steel are available if specified. The sealing surface is metalized with a nickel alloy to prevent corrosion. Composite insulation consists of an inner layer of high temperature calcium silicate and an outer layer of energy-efficient polyurethane foam. This combination cuts energy cost up to 50% over conventional conduit insulations. The fiberglass casing eliminates external galvanic corrosion, the principal cause of failure in metallic conduits. Fittings manufactured in the same fashion as the pipe. Any fitting configuration is available, making changes in directions and adaptations to existing systems simple. The Super Temp-Tite® system is joined by a bronze coupling containing a Teflon seal and a high temperature elastomer o-ring. The seals and rings are restrained in machined grooves on both sides of the coupling. A refractory composite block, bonded to the casing, locks the coupling into place. Expansion or contraction is automatically provided for at each coupling, eliminating the need for loops and other expansion devices. The heavy wall non-corrosive casing pipe and high temperature heavy-duty elastomer annulus seals prevent infiltration of ground water. These seals have proven tight in over 20 feet of water. Super Temp-Tite® is the answer to your underground high temperature steam requirements. It is in full compliance with the Army Corps of Engineers CEGS 02552 and meets the Power Piping Code ANSI/ASME B31.1.
