1 02/18 KOOL-KORE PIPING SYSTEMS SPECIFICATIONS KOOL-KORE shall be used where specified for chilled water service, using a rubber ring joining method. PVC CARRIER PIPE: Carrier pipe shall be Polyvinyl Chloride (PVC) 160 psi pipe - SDR 26 in accordance with ASTM D2241. Pipe shall be extruded from clean, virgin approved class 12454A PVC compound conforming to ASTM D1784. CASING PIPE: The casing shall be [Polyvinyl Chloride (PVC)] pipe shall be of virgin PVC resin meeting the minimum classification requirements of ASTM D1784 or [High Density Polyethylene (HDPE)]. The thickness for PVC casing shall be as shown on page three. Consult manufacturer for HDPE dimensional data. The casing ends shall butt when pipe is pushed together. This automatically sets the insertion depth of the carrier pipe. RUBBER SEALING RINGS: Sealing rings for the PVC carrier pipe shall be a molded solid compression type rubber compound suitable for the service and pressure of the system. RUBBER END SEALS: End seals for insulated KOOL-KORE shall be rubber with a compression type seal. POLYURETHANE FOAM INSULATION: The insulation shall be Polyurethane Foam and shall meet the following specifications: Type: Two component urethane Compressive Strength: 40 psi parallel min at 5% comp Shrinkage: None at 70ºF Free Rise Density: 2.0 to 3.0 lbs./cubic foot Aged "K" (70ºF - 72 hrs) 0.16 BTU-in./hour-ºF-ft.2 Closed Cell Content: 90% Insulation concentricity: Carrier Pipe shall be concentric to casing pipe. The allowable maximum deviation from centerline of carrier pipe shall be plus or minus 1/4 inch at the casing center point and plus or minus 1/16 inch at the end seals. 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 pipe OD and sleeve ID shall never be less than ½". 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
