3 .10 LEAK TESTINGA. Piping Exposed to Tank Pressure:1. Test with air or inert gas only.2. Insert pressure gauges on all sections of piping to be tested. Piping system shall stand apressure of 250 psig for a period of not less than 1 hour without showing any drop inpressure.B. Piping Downstream of Primary Regulators: Coordinate with pressure testing specified in Section15360.1. Test with air or inert gas only.2. Insert pressure gauges on all sections of piping to be tested. Piping system shall stand apressure of 50 psig for a period of not less than 1 hour without showing any drop inpressure.C. If a pressure drop on a gauge is noted, all equipment or outlets connected to the piping shall beexamined to see if they are shut off and do not leak. If no leaks are found in any of these devices,there is a leak in the piping. Test pipe joints for leakage with soap and water solution. Makerepairs to piping, then repeat test.D. Correct leaks by remaking joints with new materials; makeshift remedies will not be permitted.3 .11 PURGINGA. Purging shall be performed in accordance with NFPA 54 and NFPA 58 and with the installationand service guidebooks prepared by the National Propane Gas Association (NPGA).B. After piping has been tested and before tanks are initially filled with propane, fully purge all airfrom propane storage tanks and piping.C. Do not purge open ends of piping systems into confined spaces or areas where there are sources ofignition, unless those spaces are adequately ventilated, purging rate is controlled, and allhazardous conditions are eliminated.3 .12 INITIAL TANK FILLA. Provide initial propane fill in propane storage tanks for system testing. All air in tanks shall bepurged before filling. Provide 2,700 gallons of propane in the tank (15 percent fill) for testing ofequipment.3 .13 PAINTINGA. All aboveground piping and equipment related to the propane system shall be field painted inaccordance with section 09901. Items to be painted shall include:1. Propane tank2. Nitrogen cylinder cabinet3. Transport unloading bulkhead15480-13PROPANE GAS STORAGE SYSTEM AND APPURTENANCES
