Product Introduction
Heat Exchanger Plate and Gasket are the two core components of the plate heat exchanger. Heat Exchanger Plate is a metal plate used to transfer heat. The surface is formed into flow channels by pressing corrugations, so that cold and hot fluids flow on both sides of the plate respectively and achieve heat exchange; Gasket is a sealing component installed on the edge of the plate, which is used to guide the fluid to flow along the set path and prevent leakage between different media.

Advantages
Reliable materials
Gasket uses NBR or EPDM materials, of which NBR can adapt to the environment of −20°C to +110°C and is resistant to mineral oil and lubricating oil; EPDM can adapt to −25°C to +150°C and is resistant to steam, hot water, weak acid and weak alkali media. This ensures that the gasket still maintains excellent elastic compression and reliable sealing capabilities under the maximum working pressure.
Efficient heat conduction
The plate adopts a herringbone structure design, and the turbulent effect enhances the heat transfer efficiency. Under the same temperature difference, the heat exchange coefficient of the plate heat exchanger is 2 to 4 times that of the shell and tube type, and the overall heat recovery efficiency can reach 99%.
Easy to maintain and replace
The gasket is standardized and molded, with a clip-in or adhesive structure. It can be replaced in a single piece without disassembling the heat exchanger plate group. The standard thickness of the gasket is controlled at ±0.1mm, which is convenient for regular inspection and quick replacement.

FAQ
Q: What geometric features should be considered in the design of Heat Exchanger plates?
A: Plate embossing pitch, fold angle and wave height determine the heat transfer efficiency and pressure drop. When purchasing, you should choose a plate structure with high heat transfer coefficient, moderate pressure drop, surface roughness that meets the characteristics of the process fluid, and easy descaling and cleaning.
Q: Why is the compression performance of the gasket important?
A: Gaskets must have good elasticity and resilience under high temperature and high pressure to maintain the seal between plates and avoid leakage and efficiency reduction. The material must undergo compression permanent deformation (Creep) and creep relaxation tests to maintain the required sealing force under long-term working conditions.
Q: How to determine when the gasket needs to be replaced?
A: During maintenance, check the gasket thickness, hardness changes, and whether cracks, adhesion or corrosion occur. If the sealing surface is extruded, deformed, uneven, leaking or chemically eroded, it should be replaced immediately to ensure stable operation of the plate heat exchanger.
Q: What are the cleaning and maintenance cycles recommended for plates and gaskets?
A: Use high-pressure water or weak alkali to clean the surface of the plate to prevent the gasket from being corroded when it ages; it is recommended to disassemble and inspect once a quarter, apply an appropriate amount of anti-sticking agent and pay attention to the alignment and tightening of the plate. It is recommended to replace the gasket regularly every two years, and it should be replaced every year if it is affected by the corrosive medium environment.
Q: What details should be paid attention to when installing the plate and gasket?
A: The assembly must keep the corrugation direction of the plate consistent to avoid misalignment of the body; the gasket position must be aligned with the plate guide groove and tightly matched with the fastening bolts; the initial tightening force should be applied evenly in stages to ensure sealing and prevent deformation of the plate. After completion, a cold pressure test is required, and it can be put into operation only after confirming that there is no leakage.
