Fire-resistant steel conduit is a type of pipe used to protect wires and cables. It has excellent fire-resistant performance, which can effectively prevent the spread of flames in the event of a fire, protect the lines, and ensure the normal operation of the electrical system within a certain period of time. It is widely used in building electrical installation projects with high fire protection requirements.
Material and Structure: It is based on carbon steel or low-alloy steel, with fire-resistant coatings applied to the inner and outer surfaces of the steel pipe or special fire-resistant treatment processes adopted. Some fire-resistant steel conduits are also equipped with fire-resistant and heat-insulating layers inside, such as ceramic fibers and rock wool, to enhance the fire-resistant effect.
-
Fire-resistant Performance: It undergoes fire resistance tests in accordance with relevant standards. It can withstand a certain high temperature without being damaged within a specified time, maintain its integrity and heat insulation, control the temperature rise inside the pipe within an allowable range, and ensure that wires and cables work normally in case of fire. The fire resistance time of fire-resistant steel conduits of different grades ranges from 30 minutes to 180 minutes.

Product Features
-
High Strength: The steel base gives it high mechanical strength, enabling it to withstand large external impacts and pressures, not easily deform, and protect wires and cables.
-
Good Corrosion Resistance: The surface coating not only has a fire-resistant function but also can play a certain anti-corrosion role, allowing it to be used in different environments.
-
Excellent Insulation Performance: The steel pipe itself is insulating, and the coating also has good insulation performance, which can prevent electric leakage and short circuits.
-
Convenient Construction: It has a moderate weight, is easy to carry and install, and can adopt various connection methods such as threaded connection and groove connection to improve construction efficiency.
-
Specifications and Dimensions: There are various specifications, commonly including DN15 - DN150, etc. The outer diameter range is usually between 15mm - 150mm, and the wall thickness varies according to different specifications, which can meet the laying needs of different wires and cables.
-
Scope of Application: It is suitable for various high-rise buildings, commercial buildings, hospitals, schools, subways and other places with dense personnel or high fire protection requirements, as well as areas prone to fire in industrial plants. It is used to lay important electrical lines such as fire alarm systems, emergency lighting systems, and fire elevators.
-
Installation and Maintenance: During installation, care should be taken to avoid damaging the fire-resistant coating, and the connection parts should be sealed with fire-resistant sealant, etc. Daily maintenance mainly involves regularly checking whether the coating is damaged or peeled off, and repairing or replacing it in a timely manner if there is a problem.
