  • Estimating the Cost of Compressed Air Systems Leaks

    Aug 31, 2017 · A 1/16″ diameter hole is going to flow close to 3.8 SCFM @ 80 PSIG supply pressure. An industrial sized air compressor uses about 1 horsepower of energy to make roughly 4 SCFM of compressed air. Many plants know their actual energy costs but if not, a reasonable average to use is $0.25/1,000 SCF generated. Calculation :

  • LEAK DETECTION METHODS AND DEFINING THE SIZES OF LEAKS

    The maximum acceptable leak rate for a given product depends on the nature of product. Since the cost of leak detection (and manufacturing too hermetic envelopes) increases in inverse proportion to a leak rate, it follows that testing for unnecessary small leaks causes unnecessary rise of production costs.

  • The 10 Most Common Errors in Leak Testing | 2016-08-01

    USING THE WRONG LEAK-DETECTION METHOD. Using the bubble test method often produces the wrong results. If the tester does not see any bubbles, then it is assumed there is no leak. TESTING AT THE WRONG POINT IN TIME IN THE PRODUCTION PROCESS. It is important to think twice when selecting the best point in the production process to perform a leak test. TESTING A CONTAMINATED PART. For virtually all test methods the following should apply: Leak tests always should take place on new, unused test pieces. IGNORING TEMPERATURE CHANGES. Temperature fluctuations represent a serious problem, especially for integral leak tests using pressure decay or differential pressure measurement.

  • MnTAP – Compressed Air

    Check For and Repair LeaksUse Alternatives to Compressed AirLimit Unregulated End-UsesResourcesMnTAP Case StudiesAll compressed air systems have leaks, and large ones will be audible. Keep leaks to a minimum by correcting them as soon as they are found. Annually test your system during periods of non-production to determine its overall leak rate by looking at air loss from the supply tank. Compressed-air system leaks can be costly; a 1/8 inch diameter hole in a 100 psi system can cost you more than $1,200 per year in wasted energy, so it is worth maintenance time to fix all sizeable leaks. Even in noisy 24/7 environments ultrasonic leak detectors are available (and can be tested through MnTAP) that are a significant aid in homing in on leaks despite background noises.

  • Mistakes and Misconceptions in Valve Leak Testing

    While it is possible to observe bubbles rising in water with a leak rate of 1 x 10–4 standard cubic centimeters (cc) per second, factory tests are short in duration so the sensitivity of typical factory leak tests is around 1 x 10–3 standard cc per second. This is roughly equivalent to four cc (four game dice or marbles) of leakage per hour.
