PHE Sondex Gasket Used In Heat Exchanger Pad ISO Certificate

Product Specification

Product Description

To perform leak testing on a gasket in a Plate Heat Exchanger (PHE), you can follow these steps:

Preparation: Ensure the PHE is properly assembled with the gasket in place.

Pressurization: Introduce air or water into the PHE at a specified pressure using a pressure testing device.

Observation: Carefully inspect the gasket area for any signs of leakage, such as air bubbles or water seepage. Pay close attention to areas around the gasket where leaks may occur.

Pressure Maintenance: Maintain the pressure for a designated period to assess the gasket's sealing performance. Monitor for any pressure drops, which could indicate a leak.

Record Results: Document the testing process, including the pressure applied and any observations of leaks or issues with the gasket seal.

Addressing Leaks: If leaks are detected, identify the source of the leak and take necessary steps to address it, such as adjusting the gasket position or tightening fasteners.

By following these steps and conducting thorough leak testing on the gasket in the Plate Heat Exchanger, you can ensure that the gasket provides an effective seal and prevents any fluid leakage during operation.

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.
