2 02/18 FITTINGS: Fittings shall be uninsulated and conform to the requirements of the latest revisions of ANSI/AWWA C153/A21.53 (compact type), ANSI/AWWA C110/A21.10 (conventional type) for push-on or restrained joint fittings, or ANSI/AWWA C110/A21.10 and ANSI/AWWA C111/A21.11 for mechanical joint fittings. Fitting sealing rings shall be furnished by the manufacturer. 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 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. DUC-TITE APPLICATION ENGINEERING PIPE SYSTEM DESIGN: Standard design techniques and practices for DUC-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, the site and temperature and pressure classifications, soil conditions, and general path and elevations of the system, location and design of manholes, known obstacles, the 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. Fluid flow design will be based on Hazen-Williams formula with "C" Factor of 100, or a variation of the Euler formula for water flow.
