The gasket flange/heat exchanger is a sealing component used between the flange and heat exchanger in boilers. It prevents leaks of water or combustion gases, ensuring efficient heat transfer and safe operation. Over time, gaskets can degrade due to thermal cycling and need replacement during servicing. Using a proper gasket flange/heat exchanger is essential for maintaining boiler integrity and preventing costly water damage. This spare part is commonly required in boiler maintenance and repair tasks.
