Rim Seal Fire Protection System

Chemical and petrochemical storage farms face significant fire risks, especially concerning floating roof oil tanks. Rim seal fires pose a particular threat, often leading to catastrophic consequences if left undetected and unaddressed.

Understanding the Risk:

Rim seal fires initiate within the rim seal area of floating roof tanks, gradually spreading undetected until the entire seal area is engulfed in flames. In worst-case scenarios, the intense heat compromises the structural integrity of the tank, leading to potential sinking and full surface fires.

Prevention through Early Detection and Suppression:

Installing an Automatic Rim Seal Fire Detection and Extinguishing System is the most efficient way to mitigate such risks. This system provides automatic fire detection and instantaneous suppression within the rim seal zone, preventing fire escalation.

Components of the System:

Linear Heat Sensor (LHS) Detection System: Detects incipient fires using LHS cables, ensuring early detection and prompt response and is UL Listed

Nitrogen Pressurized Foam Modules: These modules, permanently pressurized with nitrogen, deliver foam to the rim seal area through discharge nozzles upon fire detection.

Electrical Panel-based Automatic Actuation System: Automatically activates the foam discharge module in response to fire detection signals from the LHS system, ensuring swift and effective suppression.

Operational Workflow:

Upon fire detection by the LHS system, an annunciation is triggered in the electrical panel. Simultaneously, the solenoid valve on the foam discharge module is automatically actuated, initiating foam discharge. Foam is then discharged into the rim seal area through aspirating type discharge nozzles, extinguishing the fire and preventing further escalation.

Ensuring Fire Safety:

FIRETECH’s Rim Seal Fire Protection System offers reliable and efficient fire protection for chemical and petrochemical storage facilities. With advanced detection and suppression capabilities, it provides peace of mind by safeguarding against the devastating consequences of rim seal fires.
