Thermography is a non-destructive inspection and testing method used to
measure and detect small temperature variances to find signs of deterioration
in plant sites and assets. Thermography is highly recommended in the support
and maintenance of plants and industrial equipment, offering a fast, reliable,
and cost-effective means of testing. A non-contact technique, thermography can
be used in a wide range of sectors and industries, from power plants to
petrochemical sites, steel plants, refineries, and so much more. Thermography service is likewise
applicable to the inspection of transformers, electrical rooms, broiler areas, storage
tanks, and many others.
An ideal model of inspection, thermography can help in detecting
invisible issues and problems, enabling companies to prevent costly downtime
due to unscheduled outages all the while improving the productivity of assets
and plant equipment and increasing general safety. Early detection of these
problems with the help of thermography service is
also useful in guiding corrective action for and general maintenance of assets.
The principle behind thermography is based on the premise that objects
emit thermal energy invisible to the naked eye. In thermography, an infrared
camera measures thermal energy that objects release, mapping temperature
differences of a tested object. The image that the infrared camera captures
should show the heat flow from, to, and through the object and the temperature
variances in an object can be indicative of different invisible problems like
corrosion, erosion, faulty or bad insulation, and even material and structure
flaws like voids, inclusions, or disbands.
Thermography is a useful diagnostic tool for signs of deterioration in
objects. Areas that show significantly low thermal energy could also be
indicative of energy faults and loss of power. Other benefits of thermography
service include finding hidden defects at their earliest stages, discovering
faults in metals, pipes, and even plastic parts, detecting corrosion damage,
and measuring inaccessible areas or objects that pose hazard or can only be
tested using non-destructive methods.
