Performance and application suggestions of rubber sealing ring in high temperature environment

In industrial applications, rubber seals at high temperatures play a vital role. Its performance directly affects the safety, reliability and service life of the equipment. This paper will discuss the performance characteristics of rubber seals in high temperature environment, and provide suggestions for selection and application.

performance

High temperature resistance:

High temperature environments challenge the endurance of rubber seals. High quality high temperature rubber seals can maintain stable sealing performance under high temperature conditions, generally able to withstand temperatures above 200 degrees Celsius, or even higher.

Aging resistance:

The high temperature environment is easy to lead to the aging of rubber seals, including hardening, deformation and loss of elasticity. Good aging resistance can extend the service life of the seal ring and reduce the maintenance frequency and cost.

Wear resistance:

Under high temperature conditions, rubber seals may face higher friction and wear, especially in dynamic sealing environments. The sealing ring with strong wear resistance can effectively reduce the leakage problem caused by wear.

Sealing performance:

The sealing performance under high temperature environment is strict, and the sealing ring must be able to effectively prevent the leakage of liquid or gas to ensure the normal operation and safety of the system.

Application suggestion

Choose the right material:

In the high temperature environment, the commonly used high temperature rubber materials include silicone rubber, fluorine rubber and butadiene rubber. Select the appropriate material according to the specific working temperature, medium and operating requirements to ensure that the sealing ring can work stably.

Consider the chemical resistance of the material:

Some corrosive media may be involved in the high temperature environment, and the material of the sealing ring should have good chemical resistance to prevent the expansion, deterioration or damage of the material.

Optimized seal design:

When designing the sealing scheme, considering the thermal expansion and deformation characteristics of the material under high temperature conditions, reasonable sealing structure and size design are adopted to ensure that the sealing ring can still maintain a good sealing effect at high temperature.

Regular inspection and maintenance:

The sealing ring in high temperature environment is easily affected by environmental factors. It is recommended to check and maintain the sealing ring regularly to discover and replace the aging or damaged sealing ring in time to ensure system reliability and safety.

Avoid overtemperature operation:

Avoid operating equipment outside the temperature limit of the seal, which extends the service life of the seal and reduces the risk of failure.

The selection and application of rubber seals in high temperature environments is crucial, and the correct selection and use can significantly improve the efficiency and reliability of the equipment, reduce maintenance costs, and extend the service life of the equipment. In summary, for application scenarios facing high temperature environment challenges, the performance characteristics and application recommendations of the sealing ring should be fully considered to achieve the best sealing solution.
