Principle of operation

The fire detection tube is a pressure non-metallic hose that can automatically detect fire, activate fire extinguishing devices and deliver extinguishing agents. The tube is usually installed close to or above the most likely location of the fire source. The tube detects fire through multiple detection points (linear) along the tube itself. When the ambient temperature becomes too high, the tube softens and ruptures at a set temperature, releasing the extinguishing agent into the protected area through the fire detection tube itself (direct system) or nozzle (indirect system). It combines long-term leak resistance, flexibility and effective temperature sensitivity, rupturing in a certain temperature range to spray the extinguishing agent or to transmit fire signals.

FAQ

Q1: How does a fire detection tube work?
A fire detection tube acts as a continuous, linear heat sensor. The tube is pressurized with inert gas or a fire suppression agent. When a fire occurs and ambient temperatures reach a specific threshold (such as 100°C to 110°C), the heat-sensitive polymer wall softens and ruptures at the hottest point. This sudden drop in pressure instantly activates the cylinder valve to release the fire extinguishing agent directly onto the flames.

Q2: What are the specifications of your fire detection tubes?
Our fire detection tubes are extruded from premium, heat-sensitive materials to ensure reliable rupture performance. They are available in standard dimensions—such as 6mm OD × 4mm ID—and can be fully customized in wall thickness and length to meet your system’s exact pressure ratings. Every batch is manufactured under strict factory controls to guarantee precise burst temperatures and uniform chemical resistance.

Q3: Where is a fire detection tube typically placed?

  • Fire detection tubes are installed directly inside high-risk, enclosed micro-environments where fires are most likely to start. Key placements include:
  • Electrical Infrastructure: Electrical cabinets, server racks, control panels, and switchgears.
  • Transportation Systems: Vehicle engine compartments (buses, trucks, heavy machinery).
  • Industrial Facilities: CNC machines, chemical storage lockers, and power generation equipment.

Q4: Which fire detection tube do I need for my system?
The right choice depends on your specific installation environment and engineering drawings. As a professional factory, we can fully customize the tube dimensions, material formulations, and lengths to match your technical blueprints. Contact our engineering team with your drawing specifications, and we will configure the exact tube hardness and burst parameters your automated fire suppression system requires.

Q5: Why is a fire detection tube used over traditional systems?
Traditional fire systems can be slow to react in enclosed spaces. A fire detection tube is used because it provides fast, localized, and 24/7 standalone protection without needing an external power supply. It detects and suppresses fires at the source within seconds, minimizing equipment damage and preventing catastrophic failure in critical industrial and automotive assets.
