Leak Detection & Test Systems

Description:

Leak detection and test systems verify the integrity of sealed components, assemblies, pressurized vessels, and pipeline sections by identifying the presence, location, and rate of fluid or gas loss under controlled test conditions. These systems serve manufacturing quality control, field maintenance, regulatory compliance verification, and safety assurance across industrial, defense, and infrastructure applications.

Test methods divide by leak rate sensitivity requirement and test medium. Pressure decay testing applies a controlled pressure to the test article and monitors for pressure drop over a defined dwell period — identifying leaks without requiring a tracer gas or immersion tank. Sensitivity on electronic pressure decay systems reaches 0.001 PSI per minute, detecting leaks as small as 0.1 standard cubic centimeters per minute (sccm) on small sealed components. Vacuum decay testing reverses this principle — drawing a controlled vacuum around the component and monitoring for vacuum loss caused by inward gas leakage through defects.

Tracer gas leak testing using helium or forming gas (5% hydrogen in nitrogen) delivers orders of magnitude greater sensitivity than pressure-based methods. Helium mass spectrometer leak detectors reach sensitivity levels of 5×10⁻¹² mbar·L/s — detecting leaks smaller than a single atomic diameter on hermetically sealed defense electronics enclosures, vacuum systems, and medical implant housings. Sniffer probes locate the exact position of a leak on large assemblies by scanning the outer surface and detecting local tracer gas concentration peaks.

These systems serve Pakistan’s oil and gas equipment manufacturers in Karachi and Sindh, Pakistan Aeronautical Complex aircraft component pressure testing programs, PARCO and OGDCL pipeline integrity verification operations, pharmaceutical packaging leak testing lines in Lahore, and defense ordnance facilities requiring certified leak rate verification on pressure-containing hardware before field deployment.

Tactical Supply Pakistan supplies leak detection and test systems for industrial quality control, pipeline integrity, hermetic seal verification, and defense component testing procurement across Pakistan.
