EPDM Heat Exchanger Gasket Material Sondex Gaskets Visual Inspection

Product Specification

Product Description

To test and validate a gasket after it has been assembled in a Plate Heat Exchanger (PHE), you can follow these steps:

Visual Inspection: Conduct a visual inspection of the gasket to ensure it is properly seated and aligned within the heat exchanger.

Leak Testing: Perform a leak test by pressurizing the system with air or water and checking for any signs of leakage around the gasket area. This can be done using pressure testing equipment.

Pressure Testing: If necessary, conduct a pressure test to verify that the gasket can withstand the operating pressure without leaks. Gradually increase the pressure to the specified level and monitor for any leaks.

Temperature Testing: If the PHE operates at elevated temperatures, consider conducting a temperature test to ensure the gasket maintains its integrity and sealing properties under thermal stress.

Functional Testing: Verify that the gasket performs as intended by running the PHE under normal operating conditions and monitoring for any issues related to sealing or performance.

By performing these testing and validation procedures after assembling the gasket in the Plate Heat Exchanger, you can ensure that the gasket functions effectively, providing reliable sealing and performance within the system.

Heat Exchanger Gasket/Pad for Sondex Plate Heat Exchangers:

1. Heat exchanger gaskets should resist deterioration or damage when exposed to the chemicals present in the fluids being processed. This chemical resistance ensures the longevity of the gasket and the overall reliability of the heat exchanger.
2. Gaskets must be capable of withstanding high temperatures without compromising their integrity. This is crucial for applications where the heat exchanger operates at elevated temperatures.
3. Gaskets may need to comply with industry standards and regulations. This ensures that they meet specific performance and safety criteria for use in various industrial applications.
4. Gaskets can be customized to meet specific requirements of different heat exchanger models. Customization may involve variations in size, shape, and material composition based on the unique needs of the application.
5. To ensure reliable performance, heat exchanger gaskets undergo quality testing during the manufacturing process. This includes checks for dimensional accuracy, material integrity, and sealing capability.

Gasket Material:

Manufacturing process of plate heat exchanger gaskets.

1. The first is the mixing process of rubber compounding, that is, mixing various raw and auxiliary materials according to the formula requirements;
2. The second is the step of forming the rubber material blank, that is, the rubber material is made into rubber strips through extruder equipment;
3. The third is the compression molding process, where the unvulcanized rubber strip is placed into the cavity of the hot mold, the mold is closed for vulcanization, and the rubber sealing gasket is formed in the press equipment;
4. The fourth is post-vulcanization, that is, the molded and vulcanized gasket is placed in an oven in a static state to finally complete the vulcanization;
5. The fifth is finished product inspection, that is, sampling some finished products for finished product testing according to process standards.

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.

Q&A

Q1: Does the gaskets product come with a warranty?

A1: Gasket are consumable accessories, and the replacement cycle is generally determined according to the specific conditions of use by the customer. It is related to the use environment, medium, temperature, etc. Usually we recommend purchasing more for replacement and backup purposes.
