Overview

Gaskets are essential sealing components for plate heat exchangers, installed in the sealing grooves around the plates to prevent fluid leakage. Gasket material selection is critical, requiring consideration of temperature resistance, pressure rating, chemical stability, and elasticity. Common materials include: NBR (-20 to +110°C, for water, oil, hydrocarbons), EPDM (-50 to +180°C, for hot water, steam, acids, alkalis), FKM/Viton (-55 to +230°C, for acids, alkalis, high-temperature oils), Silicone (-65 to +230°C, for some oils and alcohols), FTP (0 to +160°C, for concentrated acids, alkalis, high-temperature steam). Gasket attachment types include glued, hang-on, and clip-on (Paraclip).
