What are heat exchanger gaskets? What are their functions and advantages?

Heat exchanger gaskets are sealing components used in heat exchangers. Their primary function is to ensure a tight connection between heat exchanger components (such as plates or tube bundles), preventing fluid leakage while maintaining heat exchange efficiency. They are typically made of elastic materials (such as rubber, graphite, or metal) and can withstand high temperatures, high pressures, and corrosive media. The design and material selection of the gasket directly impact the sealing performance and service life of the heat exchanger. In plate heat exchangers, gaskets also separate different fluid channels, preventing the mixing of hot and cold fluids. Damage or aging of the gasket can lead to leakage or decreased efficiency, so regular inspection and replacement are necessary.
Heat exchanger gaskets are critical sealing components in heat exchangers, primarily ensuring stable operation in high-temperature, high-pressure, and corrosive environments.

Their core functions include:
Sealing and leak prevention: Gaskets fill gaps between heat exchanger components (such as plates, tube sheets, or shells), preventing leakage of internal fluids (such as coolant, steam, or chemicals), ensuring safe and efficient system operation. Maintaining Thermal Efficiency: Through effective sealing, gaskets prevent mixing of hot and cold fluids and the infiltration of outside air, ensuring efficient heat transfer during the heat exchange process and preventing energy loss.
Pressure Resistance and Cushioning: Gaskets possess a certain degree of elasticity, compensating for minor displacements caused by temperature changes or pressure fluctuations during operation, reducing stress and wear between metal components.
Corrosion and Temperature Resistance: High-quality gaskets are made of specialized materials (such as EPDM rubber, fluororubber, graphite, or metal) to withstand high temperatures, high pressures, and corrosive media, extending equipment life.
Easy Maintenance: Gaskets in plate heat exchangers are typically removable and replaceable, reducing maintenance costs and eliminating the need to completely replace the equipment.

Product Advantages:
Adaptability: Customizable materials and shapes are available to suit a variety of operating conditions (such as food-grade, chemical, or high-temperature applications).
Cost-Effectiveness: Gasket repairs are more economical than replacing entire components and reduce downtime.
Improved Safety: Reliable sealing reduces the risk of leakage, making it particularly suitable for environments with toxic or flammable media.
