Vacuum Tube Leak Inspection & Testing

LMATS offers a range of tube leak testing methods for heat exchangers, condensers and other tubular equipment, these methods being pressure and vacuum testing

LMATS vacuum leak tester is a simple, precise method of testing tubes in boilers, condensers, and heat exchangers. It is the fastest, most accurate means of locating leaky tubes for plugging or replacement. Using a compressed air, the vacuum leak tester create a vacuum in a tube to a desired negative pressure (e.g. average of  -0.6bar) on the vacuum gauge for at least 10 seconds. A non-variable reading on the gauge would indicate that the tube is not leaking. If the pointer on the vacuum gauge changes direction then a tube may have a through-wall discontinuity.

 The LMATS methods of The tube leak inspection testing is very fast, convenient, effective and economical for general purpose heat exchangers and condensors such as air-air or air-water heating / cooling systems.
In areas where there is a requirement to test tubes in a volatile environment or where product contamination during testing is a concern LMATS makes use of a Vacuum inspection method for testing tubes for leaks.

  • A FAST INSPECTION Without any preparation (except opening inspection hatches), the first tube of the Heat exchanger tube leakage test can be vacuum tested for leakage in less than a minute.
  • Ultra sensitive technique compared to hydro-testing or handheld helium leak methods
  • The smallest pinhole in a tube can be identified quickly using the vacuum tube testing method
  • Intrinsically safe as it powered by compressed air the vacuum leak detector method of Heat exchanger tube leakage testing and detection does not use any volatiles during the testing process
  • Faster than most other testing methods the heat exchanger is back online sooner thus saving downtime production costs
  • Cost-effective method of heat exchanger tube vacuum leakage test
  • Able to pinpoint leaks in individual exchanger tubes allowing fast repair and vessel turnaround
  • Un-reactive with any contaminants remaining in an exchanger under vacuum test
  • For water-sensitive processes this non-wetting vacuum tube test technique that eliminates the requirement to dry the heat exchanger before returning back into service
  • No  contamination of product with chemicals during the heat exchanger tube leakage test.
