Effect of the inlet flare on the shell side of the heat exchanger
Thread Content
What are the advantages and disadvantages of using a flared inlet on the shell side of a heat exchanger? Welcome to discuss in the heat exchanger equipment technology community
Advantages: Increasing the size of the shell inlet reduces the flow velocity and ρv2 (anti-erosion measures are needed if these values are high); reducing the size of the flange connections allows for the installation of anti-erosion devices if there is enough space at the bell mouth. Disadvantages: Misaligned sizes can result in higher costs; openings can significantly affect strength, and the stress distribution will vary if there are loads acting on the pipe ends.
