Super Weld-Tite is a welded steel piping system for high pressure steam, condensate, and high temperature hot water. It combines steel pipe with calcium silicate and polyisocyanurate foam insulation inside a corrosion resistant fiberglass casing.

Super Weld-Tite is a versatile, energy efficient , quality piping system. The standard carrier pipe is Schedule 40/80 A53 steel, other grades of steel are available if specified. The inner insulation is a high temperature Calcium Silicate satisfactory for temperatures to 1,200ºF and outer insulation is a thermally efficient polyisocyanurate foam with a 'K' factor of 0.14 at 70ºF. The heavy wall FRP casing combined with FRP joint overwraps prevents ground water penetration. No external coating or cathodic protection is required.

Super Weld-Tite can be designed with expansion loops or in-line expansion joints. All fittings are pre-insulated, customed fabricated to meet job requirements. Pre-insulated fittings are produced with the same carrier, insulation, casing as the pre-insulated straight sections.

Super Weld-Tite® Joint

The Super Weld-Tite joint is welded. Pipe joints are insulated using insulated half shells with FRP casing and FRP overwrap kits. All field joints are air tested using a pre-installed copper tube to make sure joints are watertight.
