Products Description
Floating roof tank foam chamber is a fixed fire protection device used to apply firefighting foam onto the surface of flammable or combustible liquids (like crude oil, gasoline, or chemicals) stored in floating roof storage tanks. It's designed according to NFPA 11 and API 650 guidelines for foam application.
Inlet Pipe Connection – Connects the foam chamber to the foam supply line.
Vapor Seal / Glass Seal Plate – Prevents vapors from backing into the foam line; breaks during foam discharge.
Deflector / Foam Distributor – Directs foam smoothly onto the liquid or the floating roof surface.
Body / Shell – Pressure-rated enclosure where foam solution expands before being discharged.
Inspection / Drain Plug – For maintenance and drainage of residual foam.

FAQ
Q: How does a floating roof tank foam chamber work?
The floating roof tank foam chamber receives foam solution from the foam system, mixes it with air, and discharges low-expansion foam through a deflector or pourer onto the tank's liquid surface, ensuring smooth distribution without agitation.
Q: Where is floating roof tank foam chamber installed on a floating roof tank?
Floating roof tank foam chambers are typically mounted on the tank's shell near the top, with a discharge pipe leading into the tank and positioned to distribute foam evenly over the liquid surface.
Q: What is the difference between a floating roof tank foam chamber and a foam pourer?
Floating roof tank foam chamber: Enclosed device with an air inlet, foam maker, and deflector-used for large storage tanks, especially fixed roof and floating roof tanks.
Foam Pourer: Simpler open device (no chamber), commonly used for dike protection or smaller applications.
Q: How many floating roof tank foam chambers are required per tank?
The number and capacity depend on:
Tank diameter and liquid surface area
NFPA 11 or API standards
Fire risk analysis
Typically, multiple chambers are installed around the tank circumference for uniform coverage.
Q: Are floating roof tank foam chambers mandatory on floating roof tanks?
Yes, for tanks storing flammable or combustible liquids, fire codes (e.g., NFPA 11, NFPA 30) require foam protection systems, which usually include foam chambers.
