How should seamless steel pipe be fireproof

Seamless steel pipes usually lose their bearing capacity at temperatures of 450 to 650 °C, causing large deformations, resulting in bending of steel columns and beams. Unusable due to excessive deformation. The fire resistance limit of unfired seamless steel pipe is about 15 minutes. The length of this time is also related to the speed at which the element absorbs heat. The following describes the fire prevention measures of several different seamless steel pipes.

1. The outer layer. It is to add an outer layer on the surface of the seamless carbon steel pipe, which can be poured in situ or sprayed. The cast-in-place solid concrete cladding is usually reinforced with steel mesh or steel to limit shrinkage cracks and ensure the strength of the casing.

2. Add water. Filled hollow seamless steel pipes are the most effective fire protection. This method can keep the temperature of the seamless steel pipe lower in the fire, and the water circulates in the seamless steel pipe to absorb the heat of the material itself. After the hot water is cooled, it can be recycled, or cold water can be introduced from the pipeline to replace the hot water.

3. Shield. The seamless steel pipe is placed in the wall or ceiling made of refractory material, or the component is hidden in the space between the two walls, and the purpose of fire prevention can be achieved by adding a little refractory material or adding refractory material. This is the most economical way to ignite.

At present, the construction of high-rise seamless steel pipes is increasing, especially for some super high-rise buildings, which use a wider range of seamless steel pipe materials. If a fire occurs in a high-rise building, the fire will not be extinguished in a short time. This requires us to increase the fire protection of building materials in the process of building design to enhance their fire resistance, and to formulate necessary emergency measures within the building. Programs to reduce casualties and property damage.
