Why Shell and Tube Heat Exchanger Maintenance is Required
Shell and tube heat exchanger is used to exchange heat between two fluids. The fluids can be crude oil, petroleum products, inorganic solvent, cooling water, steam, sticky materials or else that can accumulate deposits on the surface of tubes both inside and outside.
Accumulation of deposits causes heat exchange efficiency lower and expected temperature cannot be achieved.
Besides, corrosive fluids can initiate corrosion on tube and shell. This will cause tube or shell leaks and both fluids mix together. Fluid leakage may also come from connections.
These are some reasons why shell and tube heat exchanger maintenance is required.
Parts of Shell and Tube Heat Exchanger
A shell and tube heat exchanger has the following parts: shell side fluid in and out, tube side fluid in and out, shell, tube bundle, baffle, saddle, distributor, vent, drain, head cover and gasket.
Cleaning up shell side or tube bundle is not the only maintenance item for shell and tube heat exchanger. There are other maintenance items, which needs to be considered such like tube thickness check and corrosion.
