Lawrence Livermore <br /> National Laboratory Fuel Ta n k Pressure Test <br /> Purpose <br /> -est that there are no leaks on each of a fuel tanks containment sections that would allow for the fuel tanks <br /> contents to leak into the environment. <br /> Procedure <br /> 1. Pump out the contents of the fuel tank into an auxiliary tank prior to performing a pressure test. <br /> a. If a generator fuel tank is being pressure tested, use a fuel polisher to pump out the fuel so that <br /> contaminants can be removed from the fuel.Also ensure that a backup generator is available and connected <br /> while the pressure test is being performed on the primary generator fuel tank. <br /> 1. Seal all ports on the fuel tank and attach the pressure test piping assembly to a nitrogen bottle and the fuel tank <br /> as shown: <br /> 3 <br /> 3 PSI 3PSI <br /> Dish D* FUEL rAkK <br /> z <br /> US <br /> r. <br /> M(Sn/f� F-ft w F Sk" 1'.lF 116[ N},If glYE <br /> 1pPRnKry..A GO {~-, <br /> p <br /> 3. Pressudre the primary tank up to 3.0 PSI and then seal the tank. Record the pressure to the nearest 0.1 PSI every <br /> 15 minutes over a 60-minute period. <br /> 4. While maintaining pressure in the primary tank, pressurize the secondary tank up to 3.0 PSI and then seal the <br /> tank. Record the pressure to the nearest 0.1 PSI every 15 minutes over a 60-minute period.After the testing is <br /> completed,safely discharge the nitrogen from the fuel tank. <br /> 5. Remove the pressure test piping assembly from the fuel tank. Remove all port seals and connect any auxiliary <br /> components that were removed. <br /> Results <br /> Building Equipment ID <br /> 8 7 ,S 6714 3 59 0/4'?,ser" -- <br /> Tank Section 15 30 45 1 60 <br /> (minutes) (minutes) (minutes) (minutes) <br /> Results <br /> (PSI,0 1) 31-J I 31 S/ 3�� 3 RYI Pass Fail ❑ <br /> Secondary Al A �I ,V <br /> (PSI,0.1) Pass El Fail O <br /> Technician(s)(EMP#) Date Tested Initials <br /> a�33wc O 3r6 11-, 9-�� <br /> 1 <br />
