Spacers in heat exchanger
Web11. apr 2024 · The tubes generally constitute the most expensive component of the exchanger and are the one most likely to corrode. Tube sheets, baffles, or support plates, tie rods, and usually spacers complete the bundle. Minimum baffle spacingis generally one-fifth of the shell diameter and not less than 50.8 mm (2 in). WebThe spacers are typically made of materials that are resistant to the temperatures and pressures present in the heat exchanger. These are designed to withstand the forces of the fluid flow and maintain their position over time. Flanges and Gaskets
