Installation Precautions For Shell And Tube Heat Exchangers

When installing a shell and tube heat exchanger, pay attention to the following matters: First, ensure that the foundation is flat and stable, and the horizontality and verticality of the equipment meet the requirements to avoid stress deformation during operation. Secondly, check that the sealing surface and gasket of the shell and tube are intact, and the connecting pipes should be cleaned to prevent welding slag and impurities from entering the heat exchanger. During the installation process, it is strictly forbidden to knock on the equipment casing to prevent damage to the heat exchange tube or head. It is also necessary to pay attention to the reasonable layout of the inlet and outlet pipelines to avoid air or liquid resistance, and to set up necessary brackets and fixing devices to reduce the impact of vibration. In addition, flanges, bolts and other fasteners of suitable materials should be selected according to the design pressure level, and all connection parts should be tested for tightness. Finally, after the installation is completed, cleaning and protection work should be done to avoid foreign matter residue affecting normal use.
