Nltrile EPR EPDM Heating Exchanger Gasket for Plate Heat Exchangers in Power Plants

Heat Exchanger Gasket:

The Sealing Gasket: Vital Component for Plate Heat Exchanger Integrity

At the heart of a plate heat exchanger's operational reliability lies the sealing gasket - a critical component that plays a pivotal role in maintaining the system's performance and safety. The gasket's working temperature and pressure capacity directly determine the operational limits of the heat exchanger itself.

The primary function of the sealing gasket is to create a secure, leak-proof barrier, preventing any unwanted escape of the heat transfer medium to the external environment. Just as importantly, it must also avoid cross-contamination between the different process streams flowing through the heat exchanger. This dual role is essential for ensuring the purity and integrity of the final product, especially in sensitive applications such as food, pharmaceutical, or chemical processing.

The gasket's material composition, dimensional precision, and sealing properties are carefully engineered to meet the specific requirements of each heat exchanger design. Regular inspection and timely replacement of the gaskets are crucial maintenance practices to uphold the heat exchanger's reliable and efficient operation over its lifetime. By safeguarding the sealing function, the gasket helps preserve the overall integrity of the plate heat transfer system.

Installation method

Plate heat exchanger sealing gaskets can be divided into 3 forms according to the installation method on the heat exchange plates:

1. Direct sticking type: After applying sealant on the sealing gasket, it is directly glued into the installation groove of the heat exchange plate.

2. Plastic nail inlaid type: The heat exchange plate is designed with assembly holes, and rubber nails are designed on the side of the sealing gasket. After the sealing gasket is placed in the installation slot, the rubber nails are embedded in the assembly holes.

3. Snap-on type: There are buckles on the side of the sealing gasket, and the buckles are used to buckle the sealing gasket onto the heat exchange plate.

The sealing gasket uses different types of rubber according to different media and operating temperatures.

The steps for replacing the gasket in a heating exchanger are as follows:

1. Carefully remove the old gasket, ensuring that no scratches are made on the gasket groove during disassembly.
2. Use butanone, or other ketone solvents to remove any residue from the gasket groove.
3. Clean the gasket groove and gasket with a clean cloth or cotton swab, ensuring they are free from dirt and debris.
4. Apply adhesive evenly to the gasket groove.
5. Install the clean new gasket onto the plate, ensuring proper alignment.
6. After installing the gasket on the plate, allow it to dry naturally in a flat, cool, and well-ventilated area before installation and use.

Q&A
