DMHUI High Pressure Seal Chemical Resistance Test: Leak-Proof Performance in Harsh Chemicals

Test Dimensions:

• Chemical Immersion Test: The DMHUI high pressure seal was immersed in a range of harsh chemicals, including strong acids and solvents, for 30 days. The nitrile seal showed less than 5% volume change, while the Viton seal showed no swelling or degradation. This demonstrates the superior chemical resistance of DMHUI seals in aggressive chemical environments.
• Pressure Resistance Test: The seal was subjected to a continuous pressure of 30MPa for 72 hours. No leakage was detected, and the seal maintained its integrity, proving its ability to withstand high-pressure conditions.
• Temperature Resistance Test: The seals were exposed to cyclic temperatures, with nitrile seals tested from -40°C to 120°C and Viton seals tested from -20°C to 200°C. Both seals showed no performance degradation, confirming their exceptional resistance to extreme temperature variations.

Data Comparison:

In comparison with standard high pressure seals, DMHUI’s seal exhibited superior chemical resistance. The leakage rate of DMHUI’s high pressure seal was recorded at only 0.01ml/h, which is 10 times lower than the industry average leakage rate of 0.1ml/h.

Additional Observations:

• DMHUI seals excel in both chemical resistance and pressure tolerance, making them ideal for industries such as chemical processing and oil & gas.
• The seals’ performance in extreme environments further highlights their value in applications where reliability and durability are paramount.
• By reducing leakage and extending the service life, DMHUI seals help lower maintenance costs and improve system efficiency.

Conclusion:

The DMHUI high pressure seal’s ability to perform under extreme chemical exposure, high-pressure environments, and temperature variations proves its reliability. These results confirm that DMHUI high pressure seals are the ideal solution for industries requiring leak-proof and durable sealing solutions in aggressive conditions.
