Portable Foam Branch Pipe

The Portable Foam Branch Pipe is a lightweight yet robust foam applicator designed to deliver high-quality, expanded foam for extinguishing flammable liquid fires. Engineered for industrial and commercial firefighting operations, it is commonly used alongside inline inductors and foam concentrate systems to achieve the required expansion ratio and foam quality.

UL Listed for safety and performance, this branch pipe ensures consistent foam generation, stable discharge patterns, and excellent reach—making it suitable for fuel storage terminals, chemical plants, warehouses, aircraft hangars, and other high-risk facilities.

Lightweight construction and high discharge efficiency make the Portable Foam Branch Pipe ideal for both fixed and mobile firefighting teams.

Flammable liquid fires require specialized foam application equipment that can rapidly blanket surfaces, cut off oxygen supply, and prevent re-ignition. The Portable Foam Branch Pipe plays a critical role in such operations by converting foam solution into fully expanded, stable foam suitable for fuel hazards.

Unlike water nozzles, foam branch pipes are engineered to aerate the foam solution through a specially designed tube system. This ensures the foam blanket spreads evenly and maintains its integrity even under intense heat.

The EMACO Portable Foam Branch Pipe provides firefighters with a dependable, easy-to-operate tool capable of handling high-risk Class B fire emergencies across a range of industrial applications.

How the Portable Foam Branch Pipe Works

1. Connection to Foam Inductor & Hose Line

The branch pipe is typically connected downstream of an inline foam inductor. The inductor mixes foam concentrate with water, creating a foam solution that flows into the branch pipe.

2. Foam Aeration Process

Inside the branch pipe, air is introduced through engineered venturi openings, transforming the foam solution into expanded foam.

3. Discharge Pattern

The foam exits through a tapered nozzle, creating a concentrated yet wide foam stream that allows firefighters to coat fuel surfaces effectively.

4. Expansion Ratio & Flow Control

The branch pipe design minimizes turbulence and optimizes aeration, ensuring:

stable foam bubbles
uniform blanket formation
low pressure loss
This results in better fire knockdown performance.

1. What is the main purpose of a Portable Foam Branch Pipe?

A Portable Foam Branch Pipe is designed to generate and project foam for fighting flammable liquid (Class B) fires. It aerates foam solution into expanded foam and allows firefighters to spread a stable foam blanket over fuel surfaces to cool, smother, and prevent re-ignition.

2. What type of foam concentrates can be used with this branch pipe?

It is compatible with AFFF, AR-AFFF, and most synthetic firefighting foams, including fluorine-free options. Based on the risk level, users can pair it with different foam percentages (typically 3% or 6%) through a foam inductor system.

3. Does the branch pipe require an inline inductor to function?

Yes, in most setups. The branch pipe is supplied with pre-mixed foam solution from an inline inductor. The inductor mixes foam concentrate with water, and the branch pipe aerates this solution into expanded foam. It is possible to use it with pre-mixed foam tanks as well.

4. How far can the foam reach during operation?

The throw depends on pressure, foam type, and system configuration. At the typical working pressure of around 7 bar, the branch pipe can project foam over a considerable distance, allowing firefighters to maintain a safe operating range while covering wide hazard areas.

5. What maintenance is required after each operation?

After use, the branch pipe must be flushed with clean water to remove foam residue. The air induction openings should be checked for clogging, and the nozzle should be inspected for any damage. Periodic performance tests ensure the pipe maintains proper expansion and discharge characteristics.
