Fixed Foam Bladder Tank Vertical

Fixed Foam Bladder Tank Vertical

Specifications

1. Proportional flange standard: ANSI / BS4504 / GB;
2. Valve body material: carbon steel;
3. Liner material: rubber;
4. Proportional: standard carbon steel (SS304 stainless steel optional);
5. Ball valve: standard brass (SS304 stainless steel optional);
6. Safety valve: standard brass (SS304 stainless steel optional);
7. Pipeline system: standard carbon steel (SS304 stainless steel optional)
8. Structure: electronic with solenoid valve

Application

1. High-risk Class B fire: oil tank area, chemical warehouse, aviation fuel depot.
2. Space-sensitive scenarios: vertical occupancy is only 60% of horizontal (such as ship engine room, underground pump room).
3. Anti-pollution system: capsules physically isolate foam liquid and water to prevent premixed degradation (applicable to AFFF/AR-AFFF).

Working principle

Fire water → squeeze capsule wall → quantitative output of foam liquid → proportion mixer (3%/6%) → foam injection system → capsule emptying → automatic switching to pure water mode

Features

1. Capsule sealing (working pressure 0.3~1.2 MPa, leakage rate <0.1%/year)
2. Foam residual rate ≤1% (capsule shrinkage ratio >95%)
3. Temperature adaptability (-40°C~80°C)
3. When the capsule ruptures, the water flows directly through the sprinkler system (no risk of interruption)
4. Life cycle: tank ≥20 years, capsule 10 years (2-year hydraulic test required)

Working pressure

1. Design pressure: 1.0~1.6 MPa (in compliance with NFPA 11 bursting pressure ≥3 times).
2. Capsule pressure resistance: 0.3~1.2 MPa (low-pressure start-up to prevent bursting, high-pressure sealing to prevent leakage).
3. Test standard: Capsules are tested according to ISO 1402:2009 hydraulic pressure test (1.5 times the pressure for 30 minutes).
