2 02/18 The urethane foam insulation shall completely fill the annular space between the inner insulation and the exterior casing. The carrier pipe shall be concentric to the casing pipe providing uniform thickness of the insulation. INSULATED FITTINGS: Fittings shall be pre-insulated by Thermal Pipe Systems, Inc. using the same insulation thickness and casing as the pipe. WALL PENETRATION SLEEVES: Provide where piping passes through masonry or concrete walls, floors, and roofs. Sleeves in outside walls below and above grade, in floor, or in roof slabs, shall be schedule 40 or standard weight coated black steel pipe or shall be as specified by the Design Engineer. Space between piping or insulation casing, and the sleeve shall be sufficient to allow proper water tight sealing, but never less than 1/2". Sleeves shall be held securely in proper position and location during construction. Sleeves shall be of sufficient length to pass through entire thickness of walls or slabs. Sleeves in floor slabs shall extend 2 inches above the finished floor. Refer to typical detail of wall penetration as shown. In existing concrete manholes or building wall penetrations may be made using the "core drilling" method providing proper care is taken to drill the holes to the size needed and square to the line of the pipe. WALL PENETRATION SEALS: All wall penetrations shall be sealed to prevent water from entering the building or manhole. The sealing material shall be as specified by the engineer. SUPER TEMP-TITE APPLICATION ENGINEERING PIPE SYSTEM DESIGN: Standard design techniques and practices for SUPER TEMP-TITE shall be used. Thermal Pipe Systems, Inc. Engineering Department may, on request, provide certain detailed design aspects of the piping for each project based on the project documents and drawings provided by the Design Engineer. It is understood that the project specifications and layout drawings will specify the type of service, location of the site, temperature and pressure classifications, soil conditions, general path and elevations of the system, location and design of manholes, known obstacles, size of the carrier pipe, and the maximum permissible heat losses. It is further understood that other requirements such as the type of pipe, the location, size, and capacity of valves, traps, pumps, anchors, controls, expansion devices and special structural elements will be provided by the Design Engineer. The design provided by Thermal Pipe Systems, Inc. and their engineers for the piping will be in accordance with ANSI B31.1 and good engineering practices.
