Foam Bladder Tank Rubber Diaphragm
The Foam Bladder Tank Rubber Diaphragm is a vertical foam fire suppression storage unit with Q235B carbon steel as the main material, designed specifically for scenarios such as industrial plants, chemical warehouses, and oil depots. It can be linked with fire water systems to form a foam fire suppression system. Its main body is integrally welded from Q235B carbon steel, with a dual heavy anti-corrosion treatment of "epoxy zinc-rich primer + polyurethane topcoat", adapting to multiple indoor and outdoor environments (equipped with sun protection, rain protection, and antifreeze accessories). It can stably store and deliver various fire-fighting foam concentrates, and cooperate with water systems to achieve 3%~6% proportion foam mixing, meeting fire suppression needs for different fire intensities.

Products Features
3.1 Performance Enhancement of Carbon Steel Main Body
Q235B carbon steel is used as the main material, with a tensile strength of ≥375MPa. After welding, it undergoes stress relief treatment, improving the tank's compressive stability by 20%. The dual "epoxy zinc-rich + polyurethane" coating not only solves the problem of carbon steel's susceptibility to rust but also adapts to corrosive environments such as chemical parks and coastal warehouses, with an outdoor service life of over 10 years.
3.2 Functional Structural Design
Vertical Compact Structure: Occupies only 60% of the floor space of horizontal tanks, suitable for industrial plants and underground fire pump rooms with limited space;
Dual-Mode Control: Supports manual emergency start and automatic linkage start, meeting rapid response needs for different fire situations;
Overpressure Safety Protection: Built-in safety valve with 1.3MPa opening pressure, avoiding tank deformation due to overpressure and improving system operation safety;
Wide Foam Concentrate Compatibility: Adaptable to multiple foam concentrate types (e.g., aqueous film-forming, protein), allowing switching of fire suppression media without replacing the tank.
FAQ– CA-FIRE Dry Fire Sprinkler
Q: What is a Dry Fire Sprinkler?
A: A dry fire sprinkler is designed for unheated or low-temperature environments. Unlike wet sprinklers, it keeps water out of the pipes until activation, preventing freezing.
Q: Where can Dry Fire Sprinklers be installed?
A: They are suitable for cold storage facilities, warehouses, industrial spaces, commercial buildings in cold climates, and seasonal or remote facilities.
Q: How does the sprinkler activate during a fire?
A: The sprinkler responds to heat, opening the valve to release water quickly and efficiently, controlling the fire while minimizing property damage.
Q: Is regular maintenance required?
A: Yes. Although designed for low maintenance, annual inspections for corrosion, wear, or leaks are recommended to ensure reliable performance.
Q: Are CA-FIRE Dry Fire Sprinklers certified?
A: These are non-certified dry-type sprinklers. They are durable, cost-effective, and suitable for facilities seeking reliable fire protection without certification requirements.
