Stainless steel high-pressure filterIt is a filtration equipment designed specifically for high-pressure fluid systems, with the main material usually being 304 or 316 stainless steel, which has strong corrosion resistance and is suitable for industrial fields such as chemical, petroleum, and food industries.
Our stainless steel high-pressure series offers four filtration grades and activated carbon ranging from 5 to 0.01 microns, ensuring maximum removal of pollutants and providing different flow capacities of 725/1450 and 5000 PSI (50, 100, and 350 barg).
Method for judging the sealing performance of stainless steel high-pressure filters:
1. Sealing test standards
Pressure testing method: Use air or nitrogen as the medium, gradually increase the pressure to 100-105% of the working pressure, and hold the pressure for 30 minutes to check for leaks.
Smoke/scanning test: If smoke is released upstream or scanned by a particle counter, and there is no smoke or leakage concentration ≤ 0.1% downstream, it is considered qualified.
Differential pressure verification: The deviation between the system differential pressure and the design value after installation is ≤± 5%, and there is no significant decrease within 24 hours.
2. Key quality indicators
Sealing material: It needs to be corrosion-resistant and heat-resistant (such as fluorine rubber rings and nitrile rubber), with a compression rate controlled at 20% -30%.
Structural accuracy: The clearance between the mother frame and the sub frame should be ≤ 0.5mm, and the filter element should be adhered to the sealing surface without any raised edges.
Pressure resistance performance: It must meet the requirements of working pressure.
Practical application precautions:
Installation specifications: The sealing ring needs to be cleaned and in place, and the bolts should be tightened with torque.
Regular maintenance: The sealing ring should be replaced regularly as a consumable to avoid aging and leakage.
High temperature environment: Metal sealing (such as stainless steel corrugated pipes) or water-cooled sleeves are required for cooling.
