Material selection suggestion and effect evaluation of rubber seal ring in high pressure liquid gas system

In the high-pressure liquid gas system, the selection of rubber seals is very important, which directly affects the safety and performance of the system. This article will explain in detail how to choose the right rubber seal and evaluate its effect in high-pressure liquid gas systems.

Material selection suggestion

When selecting rubber seals suitable for high-pressure liquid gas systems, the following key factors need to be considered:

Pressure resistance: The rubber seal must be able to withstand high pressure in the system and maintain good sealing performance. Therefore, the selection of rubber materials with higher hardness and strength, such as fluororubber (FKM) or nitrile butadiene rubber (NBR), is usually a more suitable choice.

Corrosion resistance: High-pressure liquid-gas systems may contain corrosive media, such as liquid chemicals or high-pressure gases. The material of the rubber sealing ring must have good chemical corrosion resistance to ensure a long-term stable sealing effect.

Temperature resistance: In high-pressure liquid-gas systems, seals may face higher operating temperatures. The selection of high temperature resistant rubber materials, such as fluororubber (FKM), silicone rubber (VMQ) or fluorosilicone rubber (FVMQ), can ensure that it can maintain good elasticity and sealing properties in high temperature environments.

Compression permanent deformation: Consider the compression permanent deformation of rubber sealing ring under long time high pressure. Choose rubber materials with low compression permanent deformation rate to ensure stability and reliability during long-term use.

Effect evaluation

Properly selected rubber seals can play a good role in high-pressure liquid gas systems:

Excellent sealing performance: The selection of suitable rubber sealing ring can effectively prevent the leakage of liquid or gas, to ensure the safety and stability of the system operation.

Long-term durability: High pressure, corrosion and high temperature resistant rubber seals can withstand the test of long-term work of the system, reducing maintenance frequency and replacement costs.

Safety: In high-pressure liquid gas systems, the correct selection of rubber seals not only ensures the safety of equipment and personnel, but also helps to improve the overall performance and efficiency of the system.

Conclusion

Through the above material selection suggestions and effect evaluation, we hope to provide reference and guidance for you to select and use rubber seals in high-pressure liquid gas systems. The selection of suitable materials and specifications can effectively improve the reliability and efficiency of the system to ensure long-term stable operation of the system.
