Fire-resistant steel conduit

Fire-resistant steel conduit is a type of tubing used to protect electrical wires and cables, offering excellent fire-resistant properties. It effectively prevents the spread of flames during a fire, ensuring the safety of electrical circuits and maintaining the normal operation of electrical systems for a certain period. It is widely used in building electrical installation projects with high fire safety requirements.

Material and Structure: Made from high-quality carbon steel or low-alloy steel as the base material, with fire-resistant coatings applied to both the inner and outer surfaces of the steel tube or treated with special fire-resistant processes. Some fire-resistant steel conduits also include fire-resistant insulation layers inside the tube, such as ceramic fiber or rock wool, to enhance fire protection.

- Fire Performance: Tested according to relevant standards, it can withstand high temperatures for a specified period without damage, maintaining its integrity and insulation properties. This keeps the temperature rise inside the tube within an acceptable range, ensuring that wires and cables continue to function during a fire. The fire resistance time of different grades of fire-resistant steel conduits ranges from 30 minutes to 180 minutes.

- Product Features

- High Strength: The steel base provides high mechanical strength, enabling it to withstand significant external impact and pressure without deformation, thereby protecting wires and cables.

- Good Corrosion Resistance: The surface coating not only offers fire resistance but also provides some anti-corrosion protection, making it suitable for use in various environments.

- Excellent Insulation: The steel tube itself is insulating, and the coating also has good insulation properties, preventing leakage and short circuits.

- Easy Installation: Moderate weight makes it easy to handle and install. It supports various connection methods, such as threaded connections and grooved connections, improving construction efficiency.

- Specifications and Sizes: Available in a variety of specifications, common sizes include DN15 to DN150, with outer diameters typically ranging from 15mm to 150mm. Wall thickness varies depending on the specification, meeting the needs of different wire and cable installations.

- Applications: Suitable for high-rise buildings, commercial centers, hospitals, schools, subways, and other crowded places or locations with high fire safety requirements, as well as industrial plants prone to fires. It is used for installing critical electrical circuits such as fire alarm systems, emergency lighting systems, and fire elevators.

- Installation and Maintenance: During installation, care must be taken to avoid damaging the fire-resistant coating. Connection points should be sealed with fire-resistant sealants. Routine maintenance involves regular inspections for coating damage or peeling, with timely repairs or replacements as needed.
