The two pictures above are clear examples of scale findings in process pipes. The dark purple areas of the pipes signify much lower temperatures, which is generally a strong indicator of scale in a pipe.
Additionally these pictures hold a bit of history behind them as they are the result of a project started with PPCoN back in 1992. This technology provides several great benefits. It gives a complete overview of scale development, an improved insight toward optimization of scale inhibitor and a better ability for choosing the optimal time for cleaning.
IR Vision AS stays at the technological forefront by utilizing the latest and most effective thermographic inspection equipment. Furthermore we combine this with excellent analytical software programs which quantify and trend findings.
The scale deposits play an important role in how efficiently and functionally the exchanger operates. This is illustrated in the thermograms above.
IR Vision AS can help determine the level of solids in any type of uninsulated vessel. A survey could easily be accomodated even though the vessel is insulated. This is achieved by making hatches at specific points throughout of the vessel.
The different interfaces between fluid and gas can also be plotted. Furthermore, trending of any increase in solids level can also be represented graphically.
IR Vision frequently performs surveys on exhaust channels and stack to determine the lack of or damage on insulation. A high overtemperature represents a safety issue if situated nearby of in a classified area. Missing insulation can also result in a burn through of the channel/stack.
When a gas pressurized valve (in closed position) is leaking and gas is present through the valve, the first stages of a leakage can be detected by observing that the area downstream the valve has a lower temperature due to gas expansion.
A leakage through a closed diverter fluid valve is detectable because of the temperature being carried through the valve.
