Plate-Heat-Exchanger-Rubber-Liner

Plate heat exchanger rubber liner refer to rubber seals used in plate heat exchangers to ensure effective isolation and sealing of fluids between plates. These rubber liners are usually embedded in the edges of metal plates to form fluid channels and prevent leakage or mixing between different fluids.

Main functions and advantages

Main Functions

Sealing: Prevent fluid leakage and ensure the sealing of the heat exchanger.

Protection: Reduce direct contact between metal plates and fluids to prevent corrosion.

Guide fluid: Ensure that the fluid flows in the channels inside the heat exchanger to improve heat exchange efficiency.

Advantages

1. High heat transfer efficiency: The rubber liner further enhances the heat transfer effect of the plate heat exchanger, better sealing the gaps between the plates, thereby reducing heat loss and improving overall thermal efficiency.

2. Compact design: Plate heat exchangers are usually more compact than traditional shell and tube heat exchangers, and the use of rubber linings makes the equipment occupy less space.

3. Low fluid resistance: The design of the rubber liner helps to keep the fluid flowing smoothly between the plates, reducing fluid resistance, and thereby improving the flow rate and heat transfer performance of the fluid.

Materials

Plate heat exchanger rubber liner is usually made of a variety of materials, common materials include:

NBR (nitrile rubber): suitable for oil and chemical media, with good oil resistance and chemical resistance.

EPDM (ethylene propylene diene monomer rubber): suitable for hot water and steam, with good heat resistance and aging resistance.

HNBR (hydrogenated nitrile rubber): suitable for high-temperature and high-pressure environments, with higher heat resistance and chemical resistance.
