Fixed Foam Bladder Tank For Foam Suppression System
Specifications
1. Structure: manual batcher
2. Dispenser flange standard: ANSI / BS4504 / GB;
3. Valve body material: carbon steel;
4. Liner material: rubber;
5. Dispenser: standard carbon steel (optional SS304 stainless steel);
6. Ball valve: standard brass (optional SS304 stainless steel);
7. Safety valve: standard brass (optional SS304 stainless steel);
8. Pipeline system: standard carbon steel (optional SS304 stainless steel)
Application scenarios
1. High-risk explosion-proof areas: refinery storage tank area, chemical plant reactor, LNG storage and transportation facilities.
2. Continuous flame suppression requirements: oil flowing fire (capsule liquid supply ensures continuous foam coverage for 30min+).
3. Corrosive environment: offshore platform (316SS tank body resistant to salt spray), acid depot (butyl rubber resistant to pH 1~13).
Working principle
Fire protection network pressure water → Inject into tank to squeeze capsule → Foam liquid quantitative output → Proportional mixer → Generate 3%/6% mixed liquid → Foam injection device to suppress fire → Capsule emptying → Automatic switching to pure water cooling
Features
1. Zero cross contamination: Capsules physically isolate foam liquid and water to avoid premixed degradation (foam validity period extended ≥50%)
2. Ultra-high emptying rate: Foam residue ≤1% (capsule shrinkage rate ≥98%, far exceeding the 85% standard of traditional pressure tanks)
3. Extreme environment adaptation
Temperature: -40℃~120℃ (capsules are resistant to hydrocarbon solvents)
4. Intelligent monitoring: magnetostrictive level gauge + pressure transmitter (accuracy ±0.5%), linked BMS system real-time alarm
5. Maintenance economy: Capsule life 10 years (replacement cost is only 15% of tank reset)
Working pressure
1. Design pressure: 1.0~2.5 MPa
2. Capsule bursting pressure: ≥3×working pressure (ISO 1402 test)
3.Minimum starting pressure 0.3 MPa (to ensure reliable triggering of low flow system)
