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 212F to 300F steam service or Highly Saturated Nitrile (HSN) for 212F to 406F 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 1200F. 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%
