IN-SERVICE ACOUSTIC EMISSION TESTING

摘要

Discontinuities in the materials of pressurised components are relatively common. Early detection is imperative to ensure plant safety and availability. TUV SUD shows how this can be achieved with acoustic emission testing. Many pressurised components form part of installations which must be inspected periodically for aspects such as tightness, cracking and propagation of corrosion. Conventional testing provides for interior inspection, which is both time- and cost-intensive; vessels have to be drained and cleaned and the system shut down, involving safety, health and environmental measures and incurring costs from production loss.
