Helium Leak Testing

Leak Testing Services, a Non-Destructive Testing (NDT) that aims detection and characterization of Leaks in a system. Leak Testing (LT) is a Leak Testing NDT technique widely used in Power Plants (Nuclear, Thermal, and Gas Turbine), Petrochemical, Refineries, Automobiles, Valve Manufacturing, and Fabrication etc.

Various Leak test Methods are

  • Vacuum Method
  • Sniffer Method
  • Bombing Method

We have acquired the latest state-of-the-art-technique ALCATEL ASM 142 Helium Leak Detector. This equipment is capable of measuring even minute leaks in the range of 10-12 mbar l/sec. This equipment allows inspection of a large variety of system all in one unit. The system is capable of conducting the inspection in all the above said methods

Services offered by Vibrant NDT Services Pvt. Ltd. in Helium Leak test are: 

  • Online Condenser Air In-Leakage Inspection.
  • Online/offline Hydrogen cooled generator Leak Inspection.
  • Inspection to find condenser tube leaks/Heat exchanger tube leaks.
  • Inspection of columns in refinery, petrochemical industries.
  • Inspection of Rolled Joints in Nuclear Power Plants
  • Inspection of valves, pressure vessels etc
  • Inspection of pre-commissioning, pipelines in oil platforms
  • Inspection of Medicines, Pharmaceutical etc

Condenser Air Leakage

Vibrant NDT Services Pvt. Ltd. offers air inleakage helium leak tests on steam turbines and condensers worldwide. Our qualified technicians are trained experienced in locatating even the smallest condenser vacuum leaks around valve packing, steam seals, rupture disks, condensate pumps or any potential air inleakage areas.

Helium leak testing is the fastest and most cost effective method for identifying condenser tube leaks. One leaking tube can be identified in a multi-thousand tube bank within a few minutes of entering the water box. Leakage in the tube sheet is also easily identified. Re-testing after plugging or other repairs performed can be accomplished immediately. Knowledge about the gauge diameter and tube material is important to prepare the tubes and plugs to be used during esting.

Our crew come prepared with all the requisites to perform the test. In addition to unmatched leak detection expertise all our technicians are extensively trained in Safe work culture including lock-out-tag-out procedures, confined space entry and fall protection, to ensure safety at the site.

Condenser Tube Leak Detection

Condenser Tube leak detection using helium is used to find leaks in steam turbines and condensers quickly and reliably. Far superior to other types of testing using foam or plastic wrap, helium leak testing or sulfur hexafluoride can be used for both condenser air inleakage as well as detecting condenser tube leaks.

Working with a company that specializes in condenser leak detection can save you time and money. Vibrant NDT Services is specialized in condenser leak detection using helium leak testing of condensers for over 40 years and helped “write the book” with the Electric Power Research institute on the use of tracer gas to find condenser leaks within power plants.

Vibrant NDT’s Condenser Tube Leak Detection services is available at effective cost to locate your sources of condenser air inleakage or tube leaks.

Generator Leak Testing

Leak Testing Services, a Non-Destructive Testing (NDT) that aims detection and characterization of Leaks in a system. Leak Testing (LT) is a Leak Testing NDT technique widely used in Power Plants (Nuclear, Thermal, and Gas Turbine), Petrochemical, Refineries, Automobiles, Valve Manufacturing, and Fabrication etc.

Utilizing the detector probe method of helium leak testing, our technicians can locate leaks on hydrogen cooled generators that would go undetected by bubble solutions and other less sensitive methods. If a generator is failing to hold pressure after maintenance or prior to start-up it is not necessary to pressurize or test the generator with hydrogen. Using two or three standard cylinders of helium mixed with air or CO2as a tracer gas the generator can be tested , repaired and re-tested prior to being filled with hydrogen for operation.

Leak testing of operational generators is easily accomplished using one of our hydrogen detectors. This test is performed in the same manner as the helium test and provides similar test sensitivity.

We can also perform helium leak detection on the tubes and tube sheets of the hydrogen coolers and quickly identify the exact location of leakage. We have acquired the latest state-of-the-art-technique ALCATEL ASM 142 Helium Leak Detector. This equipment is capable of measuring even minute leaks in the range of 10-12 mbar l/sec. This equipment allows inspection of a large variety of system all in one unit. The system is capable of conducting the inspection in all the above said methods.
