Fire Detection Tube

Working principle

Fire detection tube is a pressurized non-metallic hose that can automatically detect fires, activate fire extinguishing devices, and deliver extinguishing agents. The tube is typically installed close to or above the most likely location of the fire source. The tube detects fire through many detection points (linear) along the tube itself. When the ambient temperature becomes too high, the tube is softened, and it will burst at the set temperature, releasing the extinguishing medium to the protected area through the fire detection tube itself (direct system) or the nozzle (indirect system). It integrates long-term leak resistance, flexibility, and effective temperature sensitivity, rupturing within a certain temperature range to spray fire extinguishing media or to transmit fire signals.

Product Parameter

Feature And Application

Feature: 

1. No power supply required, including batteries, therefore there is no need to design or install an electronic alarm control system.

2. The fire detection device itself integrates fire detection and extinguishing.

3. The fire detection tube is flexible and can extend into various narrow and complex flammable spaces and equipment.

4. It is not affected by environmental temperature, humidity, dust, grease, or electromagnetic interference, and will not give false alarms or false starts, making it very reliable.

5. Depending on the type of fire, different extinguishing agents may be utilized by the user. Our fire detection tube is compatible with most of these agents, such as carbon dioxide, heptafluoropropane, and various dry powders.

6. It can realize close distance, point-to-point  fire extinguishing (spraying extinguishing agents directly at the ignition point)in a fast and timely manner.

Application: 

Fire Safety: Pneumatic equipment in fire safety, firefighting system, fire safety alarm system.
