IR Thermography

Why IR Thermography

Infrared Thermography is an electronic technique that allows us to see thermal energy. In the industrial/commercial environment, almost everything gets hotter or cooler before it fails, making infrared cameras extremely valuable diagnostic tools with many diverse applications. As industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.

What we do

Infrared Thermography is such a valuable and versatile tool that we cannot possibly list all the applications. New and innovative ways of using the technology are being developed every day.

We use only qualified personnel to carry out Infrared Thermography Surveys. By using top of the range infrared thermal imaging equipment and software, we are able to identify faults in a variety of applications, the most popular being electrical, refractory, mechanical and storage tank.

Electrical System Inspections

Electrical surveys can identify defects such as poor connections, over loaded cables and faulty electrical equipment.

Thermography is becoming the most reliable diagnostic tool in electrical equipment maintenance. Indoor and outdoor equipment such as panels, switches, relays, transformers, cables, power grids, overhead transmission line etc. can be examined easily. Temperature variations unseen by the human eye can be detected instantly before any major events.

When electrical current passes through a resistive element, heat is generated; we can see that heat with an infrared camera. Sliding and bolted connections can become resistive through loosening, corrosion, etc. This increase in electrical resistance usually results in increase in heat generation and the camera can quickly detect it. A loose connection can dramatically influence neighbor components, raise temperature and reduce the life span of components and insulations, destroy the connector or switch due to arcs, raise power consumption and reduce voltage.

Another issue is the uneven loading of the phase’s resulting malfunctions or interference to the grid. There is no faster and easier way to detect those problems than infrared scanning of the power cables.

Mechanical System Inspections

All mechanical systems generate thermal energy during normal operation which allows infrared Thermography to evaluate the operating condition. One of the biggest problems in mechanical systems is excessive temperature. This excessive heat can be generated by friction, cooling degradation, material loss or blockages. An excessive amount of friction can be caused by wear, misalignment, over or under lubrication and misuse. Since most equipment or processes are designed to eliminate thermal energy under normal operation, simply identifying a thermal pattern does not mean a problem has been located. The Thermographer must be familiar with the mechanical components being evaluated. Once a normal thermal pattern is obtained and understood, any deviation from this normal pattern will then provide evidence of a suspect problem developing. Thermography is an excellent tool for locating a problem on mechanical components.

Furnace, Boiler,Process Heater, Refractory Equipment, Pipeline Insulation, Cold Storage InsulationsInspections

We inspect Furnace, boiler and refractory equipment under normal loads and operating conditions. By performing an infrared scan of your boiler and refractory system in real time. Our inspection can help you understand the practical impacts of emerging or existing Furnace, boiler, process heater, refractory equipment,pipeline, and cold storage problems.

  • Scan the exterior of Furnace &boiler for refectory damage or locate warmer areas where potential refectory damage may occur.

  • Insulation deterioration

  • Piping insulation and leaks

  • Valves inspection

  • Tank leakages, insulation degradation

  • Cold storage insulation &cooling losses

Heater Tube Inspections

The furnace is inspected with the intention of finding out if the tubes were operating within the design temperature limits or not. The primary aim is to check whether the furnace tubes are coked or not. If it is coked decoking of the tubes during the shutdown is necessary. Flame impingement causes coking to take place.
