Fire-Fighting Foam Delivery System

A fixed piping system laid on the floating roof that delivers fire-fighting foam to the rim seal area and to any other designated point on the roof. It connects to the foam supply at the tank shell through a flexible or articulated section that follows the roof, and distributes the foam uniformly around the circumference so that a rim-seal fire is extinguished at its source. It is normally designed and supplied together with the rim seal and the foam dam as one integrated fire-protection package.

Advantage:
1. Delivers foam directly to the rim seal, where the majority of floating-roof tank fires start.
2. Provides uniform distribution around the whole circumference for fast and effective extinguishing.
3. Follows the floating roof through its full travel without interrupting the foam supply.
4. Fixed installation means no delay and no dependence on manual handling during an incident.
5. Corrosion-resistant pipe and fittings suitable for long-term roof-mounted service.
6. Designed and supplied with the rim seal and foam dam as one integrated package.
