WebSep 8, 2024 · Corrosion and fouling. How might a heat exchanger flow be restricted or blocked? The process fluids can corrode the surfaces they touch, leading to rust build up or scaling that can reduce the diameter of the tubes and restrict flow. Also, impurities in the process fluid can build up in low-velocity areas of the heat exchanger. Web5. Chemical fouling: Chemical fouling occurs when the fluid being processed reacts with the heat transfer surfaces and forms a layer. This can reduce the heat transfer coefficient and cause corrosion. cloudbase sleeping mat https://internet-strategies-llc.com
