Heat Exchanger Sealing Gasket

How to choose material for PHE plate?

Factory Produced NBR Or EPDM Rubber Sealing Gasket For GEA Replacement

NBR (Nitrile Butadiene Rubber) is commonly chosen for gaskets in Plate Heat Exchangers (PHE) due to its excellent oil resistance, flexibility, and cost-effectiveness. NBR gaskets are suitable for general-purpose applications where resistance to oils and fuels is important. They provide reliable sealing properties and are relatively affordable compared to other gasket materials. NBR gaskets are also known for their good mechanical properties and durability, making them a popular choice for a wide range of applications in PHE systems.

When selecting the sealing gasket material in a heat exchanger, you need to consider the following points:

1. Working conditions: Select the appropriate sealing gasket material according to the operating temperature, pressure and medium characteristics of the heat exchanger to ensure that it can have good sealing performance under specific working conditions.

2. Corrosion resistance: Select a sealing gasket material with good corrosion resistance according to the chemical properties of the medium to prevent corrosion damage to the sealing gasket by the medium.

3. Sealing performance: Choose a sealing gasket material with good elasticity and sealing performance to ensure that it can effectively fill gaps and prevent leakage.

4. Service life: Consider the wear resistance and aging resistance of the sealing gasket material, choose a material with a longer service life, and reduce the frequency of replacement.

Taking the above factors into consideration, select the appropriate sealing gasket material according to specific working conditions and requirements to ensure the safe operation and long-term stability of the heat exchanger.

The main materials of rubber pads include the following rubber, graphite, plastic, etc.

Rubber: The rubber gasket has good elasticity and sealing properties, which can effectively prevent medium leakage and ensure the normal operation of the heat exchanger.

Graphite: Graphite rubber pad has the characteristics of high temperature resistance and corrosion resistance. It is suitable for high temperature and high pressure environments. It can effectively prevent medium leakage and extend the service life of the heat exchanger.

Plastic: Plastic gaskets are mainly used in occasions with special requirements, such as high media requirements. They can provide good corrosion resistance and ensure the safe operation of the heat exchanger.

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.

Q3: If could do customize gasket for PHE?

A3:To customize a gasket for a Plate Heat Exchanger (PHE), you can follow these steps:

Identify Requirements: Determine the specific requirements of your application, including operating conditions, fluid compatibility, temperature range, and pressure ratings.

Select Material: Choose a suitable gasket material based on the identified requirements. Common materials include NBR, EPDM, Viton, PTFE, and silicone.

Design Specifications: Provide detailed design specifications such as dimensions, thickness, shape, and any special features required for the gasket.

Consult Manufacturer: Contact a gasket manufacturer or supplier who specializes in custom gaskets for PHE systems. Provide them with your specifications and discuss customization options.

Review and Test: Once the customized gasket is manufactured, review it to ensure it meets your requirements. Conduct testing if necessary to verify its performance under operating conditions.

By following these steps and working closely with a gasket manufacturer, you can customize a gasket that is tailored to the specific needs of your Plate Heat Exchanger system.
