FAQ’s
Heat exchangers are engineered to endure considerable thermal stress; however, they are not everlasting. Various factors can lead to the formation of cracks over time: Age and Normal Wear. The typical lifespan of a heat exchanger ranges from 10 to 20 years, contingent upon usage patterns and maintenance practices.
Shell-and-tube heat exchangers are commonly utilized due to their durability. They facilitate heat transfer between process fluids and cooling media such as water or air. Additionally, shell-and-tube heat exchangers play a crucial role in gas processing, condensing, or vaporizing gases at various stages.
The fluids within heat exchangers generally flow swiftly to enhance the transfer of heat through forced convection. This swift flow leads to pressure losses in the fluids. The efficiency of heat exchangers is defined by their ability to transfer heat in relation to the pressure loss experienced.
