Helium leak detection services

A combined nitrogen purge with a helium leak test is used in the commissioning and start-up of onshore and offshore process plants throughout the world. Aker Qserv nitrogen pumps are rated at 180,000scf/hr and capable of working to 10,000psi. They are soundproofed to 80dB(A) and built to the highest standards, meeting all current legislation.

The helium leak detection (HLD) equipment that is used by Aker Qserv includes the latest mass spectrometer technology, offering superior accuracy and reliability. On average, a leak can be detected, logged and the mass spectrometer can be reset within 20 seconds. This accuracy and reliability is then passed on to clients who can commission the plant knowing that it is truly leak free.

Aker Qserv HLD services can be used to undertake:

• Pressure testing
• Leak detection
• Valve seat leakage
• Start-up
• Shutdown / turnaround
