Heat Exchanger Gaskets
Heat exchanger gaskets are critical sealing components designed to prevent leakage between heat exchanger plates, shells, and channels while ensuring efficient heat transfer. They provide reliable sealing under high pressure, temperature variations, and aggressive process conditions.
Overview
Heat exchanger gaskets are used to seal the interfaces between heat exchanger components, ensuring that fluids transfer heat efficiently without mixing or leaking. They play a vital role in maintaining system safety, performance, and operational efficiency.
Function & Purpose
- Prevents leakage between hot and cold fluid channels
- Maintains pressure integrity within the heat exchanger
- Ensures efficient heat transfer without fluid contamination
- Compensates for thermal expansion and contraction
Heat Exchanger Principle
Heat exchangers transfer thermal energy between two or more fluids without allowing them to come into direct contact. One fluid absorbs heat while the other releases it, enabling controlled temperature regulation in industrial and mechanical systems.
