Thermal Pipe Systems, Inc. SUPER WELD-TITE® with Composite Insulation and FRP Casing For High Temperature Hot Water and Condensate Super Weld-Tite is a dual insulated pipe system with a filament wound fiberglass casing. The insulation combines calcium silicate with polyurethane foam. As an alternative, Foamglas® may be substituted for calcium silicate to insure protection against moisture absorption. The fiberglass casing provides a high strength, corrosion resistant jacket that is much more durable than PVC. The result is a thermally efficient product for use in high temperature hot water and condensate service. This welded product can be designed with expansion loops or inline expansion joints. All fittings are pre-insulated. Field joints closures include insulated half shells with FRP casing and FRP overwrap kits. A tube for air testing field joints is pre- installed. No external coating or cathodic protection is required. Super Weld-Tite is available in sizes 1-1/2” through 16” and is suitable for temperatures to 450ºF. TECHNICAL DATA SUPER WELD-TITE® PIPE
