0 0 <br />Primary Piping System Installation <br />The normal recommended procedure is to conduct <br />a hydrostatic cyclic pressure test. The piping system is <br />subjected to 10 pressurization cycles at 1112 times the <br />anticipated or design operating pressure. NOTE: For low <br />pressure applications, it is best to use the pressure rating <br />of the pipe as the design operating pressure, i.e. test at <br />11/2 times the cyclic rating. The test pressure should not <br />exceed 11/2timesthe maximum rated operating pressure <br />for the lowest rated element in the system. Pressure <br />is then kept on the system for 1-8 hours while the line is <br />inspected for leaks. <br />Air Test Procedures and Safety Precautions(') <br />TESTING WITH AIR OR GAS IS EXTREMELY <br />DANGEROUS AND SHOULD NOT BE DONE. CONSULT <br />YOUR FGS REPRESENTATIVE OR CALL 501-618-2243 <br />FOR TECHNICAL ASSISTANCE. IF YOU CONTEMPLATE <br />EXCEEDING THE RECOMMENDED PRESSURES FOR <br />THE LOWEST RATED ELEMENT OF THE SYSTEM OR IF <br />YOU CONTEMPLATE USING AIR OR GAS IN SPITE OF <br />THE WARNING, REVIEW ALL SAFETY PRECAUTIONS <br />BEFORE STARTING THE TEST. <br />If testing with air or gas is required or requested to be <br />performed, the following testing procedures and precautions <br />must be followed. As in any system Mere pressure is <br />employed, adequate safety precautions must be exercised. <br />EXERCISE DUE CARE IN INSTALLING AND TESTING <br />THE PIPING SYSTEM. <br />Visually inspect all bonded joints for proper Insertion <br />and adhesive cure prior to pressurizling the piping <br />EjITt=m r;-nUMAL <br />r7nT <br />jj:W=- <br />CALr-AJ I <br />Iiiing system.
