NBR Heat Exchanger Gasket

Product Description

Heat Exchanger Gasket/Pad for Sondex Plate Heat Exchangers:

1. Heat exchanger gaskets are typically made from various materials to suit specific operating conditions. Common materials include elastomers such as Nitrile (NBR), EPDM, Viton, and others. The choice of material depends on factors like temperature, pressure, and the nature of the fluids being processed.
2. The primary function of a heat exchanger gasket is to create a tight seal between adjacent heat exchanger plates. This seal prevents the mixing of the fluids on the hot and cold sides of the exchanger, ensuring efficient heat transfer.
3. Gaskets must be compatible with the fluids and temperatures involved in the heat exchange process. Different gasket materials have varying resistance to chemicals and temperature extremes, making it essential to choose a material suitable for the specific application.
4. Heat exchanger gaskets come in various designs and shapes to match the corresponding plate patterns of the heat exchanger. The design may include features like grooves, ridges, or special geometries to enhance the sealing performance and stability.
5. Gaskets are designed to be replaceable, allowing for easy maintenance of the heat exchanger. When a gasket wears out or loses its sealing properties, it can be removed and replaced without requiring the replacement of the entire heat exchanger.

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.

Q2: Is there a discount available for wholesale or bulk purchases?

Answer: Yes, we offer discounts for wholesale and bulk purchases. If you are interested in purchasing a large quantity of items or engaging in wholesale business, please contact our wholesale department or customer service team for information regarding wholesale discounts and minimum purchase quantities.
