Vietnam High Pressure Water Treatment System Filter Seal Upgrade

Industry: Industrial water treatment/filtration equipment

Country: Vietnam

Pain point:

The customer’s original rubber ring sealed stainless steel filter leaked seriously under high pressure conditions:

1. High pressure failure: 15-20Bar working pressure caused the rubber ring to deform and the seal to fail;
2. Maintenance loss: Leakage aggravated equipment corrosion and frequent shutdown to replace seals.

Solution:

Structural reconstruction:

▶ Flange-type stainless steel filter replaced the threaded interface, and the pressure bearing capacity was increased to 25Bar+;

Seal upgrade:

▶ Metal hard seal + flexible graphite gasket double protection to adapt to pressure fluctuations;

▶ Cancel the vulnerable rubber ring structure to eliminate the source of leakage.

Results:

✅ High pressure test 20Bar continuous operation with zero leakage, exceeding customer expectations;

✅ Service life increased by 3 times, annual maintenance cost reduced by 60%;

✅ Adapt to the original pipeline interface, and the transformation does not require system shutdown.

Customer value:

💧 Eliminate leakage: Flange hard seal solves the problem of high-pressure penetration;

⚙️ Long-term stability: The design without rubber rings eliminates aging and failure;

📉 Reduce costs and increase efficiency: No frequent maintenance is required in the hot and humid environment of Vietnam.
