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.
