Product Description
Nltrile EPR EPDM Heating Exchanger Gasket for Plate Heat Exchangers
in Power Plants
Heat Exchanger Gasket:
1. The plate heat exchanger sealing gasket is a crucial component
in heat transfer equipment. It plays a vital role in maintaining
the operational integrity of the plate heat exchanger. The gasket's
working temperature determines the temperature limits of the heat
exchanger, and its working pressure capacity is also a limiting
factor. The primary function of the sealing gasket is to ensure a
secure seal, preventing any leakage of the heat transfer medium to
the external environment and avoiding cross-contamination between
different materials.

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.
| Main Body Gasket | Operating Temperature (℃) | Suitable Fluid |
| NBR | -15 ~ +135 | Water, Sea water, Mineral Salt, Brine |
| EPDM | -25 ~ +180 | Hot water, Vapour, Acid, Base |
| F26 | -25 ~ +230 | Acid, Base, Fluid |
| FTP | 0 ~ +160 | Concentrated acid, Base, High temperature oil, Vapour |
| FKM | -25~200 | Steam acid,98% SO2,Cl water. |
The steps for replacing the gasket in a heating exchanger are as follows:
- Carefully remove the old gasket, ensuring that no scratches are
made on the gasket groove during disassembly.
- Use butanone, or other ketone solvents to remove any residue from
the gasket groove.
- Clean the gasket groove and gasket with a clean cloth or cotton
swab, ensuring they are free from dirt and debris.
- Apply adhesive evenly to the gasket groove.
- Install the clean new gasket onto the plate, ensuring proper
alignment.
- 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
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
