Moisture Under Insulation
Benefits of TRACERCO Diagnostics™ MUI
- Detection of moisture under insulation without any preparatory
work
- No destruction of integrity of insulation during the measurement
- No interference from normal processing operations
- Can identify the precursor to corrosion before corrosion takes
effect
Prevention of Corrosion Under Insulation (CUI) is a major concern in
today’s process industries. The presence of CUI can lead to catastrophic
failure of vessels, pipe work and transfer pipelines that can result in
environmental discharge, explosion or harm to workers or members of the
general public. It is therefore essential that an effective CUI inspection
program is implemented as part of a process plant preventative maintenance
schedule. However, traditional techniques employed tend to measure actual
corrosion presence rather than moisture that acts as the pre-cursor to
metal work degradation. Working closely with a large refinery operator
experiencing significant issues with CUI Tracerco has developed a non-intrusive
measurement technology that is able to identify the presence of moisture
in insulation that can be used on a wide range of process vessels and
transfer lines. A TRACERCO Diagnostics™ MUI Scan responds specifically
to moisture presence within insulation. It can very quickly identify wet
insulation that may lead to corrosion and ultimate failure of plant vessels
and pipe work. The technique has been developed so that there is no requirement
to remove any part of the insulation prior to measurement. The service
is carried out by a highly trained Tracerco field technologist using portable
field equipment. The service has been designed to provide instantaneous
results, allowing our field technologists to immediately identify sections
of insulation containing moisture that can be quickly repaired or further
measurements carried out to determine whether CUI has occurred.
