Leak Detection using Acoustic Emission
|
Valve Leakage
มล procedures for the detection of
leaks through valves have been developed for use in refineries,
chemical plants and offshore platforms. It enables estimation of
through-valve gas losses and leak rate.

Pipeline Leakage
Inspection of whole structure performed during operating
conditions,
even
of difficult-to-reach areas. Requires minimum access to surface
for sensors mounting.

Storage Tank Leakage
The
inspection (TankPAC method) consists of attaching sensors to the
outside of the tank and monitoring for emission resulting from
leakage or active corrosion of the floor.
