Plate and gasket are the critical part of a removable Plate Heat Exchanger. The main function of the plate is to isolate the medium and perform heat exchange. Its main materials are stainless steel (304/304L, 316/316L, 254SMO), titanium, nickel, titanium-palladium alloy, Hastelloy, etc. The sealing gasket is installed in the gasket groove around the plates to seal the periphery between the plates to prevent the fluid from leaking out, and according to the design requirements, seal part of the corner holes so that the hot and cold media flow according to their own flow paths. The structure of the plate heat exchanger consists of a fixed frame, a movable frame and corrugated plates sandwiched between the two frames. Hot and cold liquids pass sequentially through the area between the corrugated plates separated by sealed elastomer paths. To prevent leaks, good gasket elastomers are installed around the perimeter of the plates and large fastening bolts are used to hold the plates together. The structure of the plate heat exchanger makes sealing a key part of this equipment, responsible for the service life of the entire equipment. Depending on the process medium, the gasket must be chemically and/or temperature resistant. Spetech supplies seals for most existing plate heat exchangers: power industry, petroleum processing, food and beverage industry, sugar industry, chemical, pulp and paper industry. The most commonly used materials are: NBR, HNBR, EPDM, FPM (different grades). There are two basic ideas for the installation of seals: glue seals and clip seals. Clip-on washers do not require any adhesives for installation. This modification makes it possible to mount the spacers by installing clips in the grooves in the plate. As a result, the gasket is highly resistant to pressure and can be replaced quickly and easily.
