Pipeline and Reservoir Characteristics The evaluation testing was conducted in a pipeline with a capacity of 4.22 gallons with an inside diameter of 2.22 inches and a length of 21 ft. The pipeline construction material was ( ) steel (X) fiberglass ( ) flexible materials. The capacity of the liquid reservoir is approximately 0.56 gallons The dimensions of the reservoir are approximately 15 inches tall with a cross section surface area of approximately 8.66 square inches The liquid in the interstice was brine (30% CaC121. The sensor spacing used to measure the reservoir level alarms is 11.6 inches for a pipeline length of 300 ft. The sensor operating principle is can be any liquid that produces a signal change from the sensor. (e.g., float switches or optical switches) The approximate volume change to produce an alarm was 1,000 ml when the float is initially at the midpoint of the reservoir. The sensor(s) was previously evaluated (X) yes ( ) no. If so, reference the evaluation (see Appendix C) Pressure Test The tests were conducted with the primary line pressurized to 100 psi. The worst-case level change in the liquid reservoir was observed to 0.00125 inches per psi change in pressure from 0 psi to 100 psi. The liquid used to pressurize the primary pipe was water . Temperature Effects Without Trapped Vapor The nominal temperature of the hot product circulated through the line during the test was 100 deg F. The initial ambient temperature of the liquid in the interstice was 63 deg F. The final interstitial temperature was 100 deg F A total volume of 60 - 70 gallons passed through the line during the test. The temperature difference was 37 deg F. The level change in the reservoir was 0.28 inches. The level change was determined to be 0.0076 inches per deg F. The nominal temperature of the cold product circulated through the line during the test was 32 deg F. The initial temperature of the liquid in the interstice was 71 deg F. The final interstitial temperature was 37 deg F A total volume of 60 -70 gallons passed through the line during the test. The temperature difference was 34 deg F. The level change in the reservoir was 0.25 inches. The level change was determined to be 0.0073 inches per deg F. Liquid Filled Interstitial Monitoring—Results Forms Page 2 of 4
