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.
