Ultrasound measurements

Air, smoke and gas tightness are important in relation to:

  • the conservation of fuel and energy (in buildings and temperature controlled spaces)
  • optimalisation of the comfort (controlling the flow in  passive houses, temperature and acoustic insulation,..)
  • improving fire safety (smoke leak prevention)
  • pollution prevention (ie leaking tanks, spreading of noxious gases,..)
  • eliminating smell disturbance in offices (near processing plants, in refineries,..)

Upon request we perform customized non-destructive and reliable ultrasound measurements for:

1- Land based applications:

  • tightness testing of (fuel)tanks:above ground tanks (with visualisation of the leak location and intensity)
  • underground tanks (no visualisation possible, but certainty of no leakage)
  • air tightness or permeability testing of buildings and residential houses:
    • on prefab structures, as a quality control before leaving the factory
    • as a building prescan, to resolve  leaks at an early stage (while they can still be rectified in an economical way)to measure compliance with fire security (smoke
  • leak detection on pipes and tanks containing pressurized air or gasses
  • water-wind-and noise testing in the automotive sector…

2- Off-shore structures and ship applications:

  • general tank tightness testing
  • testing of water and weather tightness of marine structures and equipment like:
    • watertight doors  and bulkheads
    • access hatches and bulk carrier hatch covers (to avoid claims and damage to cargo)
    • portholes and windows
    • electric cable and pipe penetrations,…
    • Insulated immersion suits
  • leak detection on pipes and tanks containing pressurized air or gasses
  • thermal and acoustic tightness testing on pleasure boats and commercial yachts

Were possible, our reports contain a still of the visualisation of location and the extend of the detected leak(s), similar to the IR (thermal) detection method.

Remarks:

-The used ultrasound methode is a convenient alternative to the more cumbersome and time consuming IR techniques, blowerdoor testing, water-or smoke testing, hose testing,…

-Testing on marine structures is done with type approved equipment. Protocols used are accepted by several P&I clubs and IACS members. Call us for info.
