Heat exchangers are often exposed to temperature extremes, both inside and outside of the system. Process fluids are often heated to high temperatures, while others, such as refrigerants, are kept extremely cold. Some heat exchangers are located outside, making them susceptible to temperature extremes … Ver más Perhaps the most important reason for keeping temperature in bounds is to prevent dangerous phase changes. While some heat exchangers are specifically designed for phase … Ver más How might a heat exchanger flow be restricted or blocked? The process fluids can corrode the surfaces they touch, leading to rust build up … Ver más Pressure excursions come from phase changes and from restricted flow. Phase changes have been previously discussed, but restricted flow can also raise the pressure. If a pump is pushing a process fluid into a heat … Ver más Leaks can occur due to corrosion, mechanical damage, overpressure and other such conditions.
