PERMA-PIPE®/RICWIL® COPPER-GARDTM — GUIDE SPECIFICATION 1.0 GENERAL 1.1 Underground piping system shall be PERMA-PIPE®/RICWIL® Copper-Gard and shall consist of integral sealed, 20-foot long units of copper tubing insulated with rigid polyurethane foam, which is protected with a PVC outer jacket and factory-applied latex coating on the ends of the insulation. tin-lead solders are not acceptable. 3.0 INSTALLATION AND TESTING 3.1 All pipes, fittings and o-ring couplings shall be installed in accordance with the manufacturer’s recommendations. All solder joints shall be hydrostatically tested prior to pouring thrust blocks. Immediately after installation in the ditch, a partial backfill shall be made in the middle of each unit leaving the joints exposed for inspection. After all thrust blocks are poured and cured, a hydrostatic test of — psig (or 11/2 times operating pressure) shall be required for a period of four hours. Basic Pipe Units 2.1.1 Pipe shall be Type”K” or “L” (ASTM B-88) copper tubing. 2.1.2 Insulation shall be a rigid, 90 to 95 percent closed-cell polyurethane with 2.0 pound per cubic foot nominal density and thermal conductivity (K) of .14 BTU IN. (HR.) (SQ. FT.) (oF) at 73o F. 2.1.3 Jacket shall be a Type 1 Grade 1 Polyvinyl Chloride (PVC) with a minimum wall thickness of .060 inches. 2.2 After hydrostatic testing, complete backfilling. Backfill material and compaction shall be in accordance with the manufacturer’s recommendations. Do not use tracked or wheeled vehicles for tamping. Preinsulated Copper Pipe with O-Ring Coupling for Condensate Chilled and Hot Water 2.2.1 Coupling shall be machine-grooved for o-ring seals. Coupling shall be insulated, jacketed and sealed. 2.2.2 All fittings shall be ASA B16.22 wrought copper fittings. Solder joints shall be made with silver brazing alloys melting at above 1100oF. 50-50 PERMA-PIPE® factory-insulated piping systems — leading the industry since 1910 — used for distribution of hot and cold water, steam, condensate, oil and other viscous materials. PERMA-PIPE representatives are located in all major United States and Canadian cities. PERMA-PIPE will provide design service and assistance to engineers, owners and contractors. Field instruction for installation personnel will be provided to teach proper handling and to show assembly techniques to supervisory personnel that should be practiced during installation. PERMA-PIPE warrants its products to be free from defects in material and workmanship. Claims for shortages or apparent defects must be made within 30 days after delivery or before installation, whichever occurs first. With respect to latent defects, PERMA-PIPE will replace or repair any materials which prove defective withing a period of one year after shipment provided the materials have been properly installed, operated and have not been damaged by neglect or abuse.
