Production introduction
Foinbo® carbon steel foam bladder tank is a key component of a foam fire suppression system used in industrial facilities, airports, petrochemical plants, marine terminals, power stations, warehouses, and fuel storage facilities. It stores foam concentrate separately from water while providing a reliable method of proportioning foam into the fire protection water supply without requiring an external power source.
Carbon steel foam bladder tanks are widely recognized for their durability, cost-effectiveness, and ease of maintenance. They are designed to work with a balanced pressure foam proportioner, ensuring an accurate foam concentrate ratio during firefighting operations.

FAQ
Q: What's the difference between carbon steel and stainless steel foam bladder tank?
Carbon Steel: Lower cost, mature pressure vessel process, internal epoxy anti-corrosion lining; suitable for most indoor pump room environments. Regular anti-rust coating maintenance required.
Stainless Steel (304/316): No internal lining, anti-corrosion for coastal, high humidity or acid mist outdoor sites; higher purchase cost.
Most industrial standard foam systems adopt carbon steel bladder tanks for cost performance.
Q: How to select vertical or horizontal tank?
Choose Vertical: Limited floor space, small/medium capacity (200–5000L), indoor pump room installation.
Choose Horizontal: Low ceiling height, large capacity (6000–15000L), outdoor open depots, easy bladder replacement inspection.
Q: Which bladder material should I choose?
NBR Nitrile Rubber: Standard match for common AFFF, FFFP synthetic foam, low cost, shelf life 5–8 years.
EPDM/Hypalon: Alcohol-resistant, for AR-AFFF, ATC alcohol-resistant foam; must select this type for alcohol, ketone, ester solvent fire projects.
Q: Can the tank work under variable water flow?
A: Yes. Balanced pressure proportioning design automatically adjusts foam output with water flow, stable mixing ratio from minimum to rated flow, suitable for multi-area simultaneous fire discharge.
