1 02/18 SUPER TEMP-TITE PIPING SYSTEMS SPECIFICATIONS STEEL CARRIER PIPE: Carrier pipe shall be black steel per ASTM A-53, Grade B [welded][seamless] or ASTM A-106 [seamless], schedule [40] (std. weight for 12”) or schedule [80] (extra heavy weight for 10” and 12”). The pipe shall be machined and metalized to provide a satisfactory sealing surface for the sealing rings. The metallizing shall be a high nickel alloy applied to an excess thickness and then machined to the required OD. BRONZE COUPLING: The bronze coupling shall meet ASTM B62 for 3” - 6” and ASTM B61 for 8” - 12”. TEFLON SEALING RINGS: The molded and machined Teflon sealing rings shall consist of stainless steel spring-loaded TFE seals. RUBBER SEALING RINGS: The secondary rubber sealing rings for SUPER TEMP-TITE shall be a special molded high temperature elastomer. The ring surfaces shall be smooth and free from all porosity and internal voids. FIBERGLASS CASING PIPE: The casing for the SUPER TEMP-TITE piping system shall be Reinforced Thermosetting Resin Plastic (RTRP) pipe manufactured by the filament winding process. The casing pipe shall be wound to meet ASTM D2310 classification RTRP-12E. RUBBER END SEALS: The end seals shall be Ethylene Propylene Diene Monomer (EPDM) heat resistant compound for 212F to 300F steam service or Highly Saturated Nitrile (HSN) for 212F to 406F steam service. The seals shall be molded using a properly vulcanized compound. The seal surface shall be smooth and free from all porosity and internal voids. CALCIUM SILICATE INSULATION: The calcium silicate insulation shall be a hydrous material satisfactory for temperatures to 1200F. Insulation shall conform to ASTM C-533 and Mil Spec Mil-1-2781. POLYURETHANE FOAM INSULATION: The insulation shall be Polyurethane Foam conforming and shall meet the following specifications: Type: Two component urethane. Compressive Strength: 40 psi parallel minimum at 5% comp. Shrinkage: None at 70ºF Free Rise Density: 2.0 to 3.0 lbs/cubic foot Aged "K" (70ºF - 72 hours): 0.160 BTU•in/hr•ft²•ºF Closed Cell Content: 90%
