　　This method has the advantages of good fireproof and heat insulation performance, construction is not restricted by the geometric shape of seamless steel pipe, and generally does not need to add auxiliary facilities, and the coating quality is light, and there is certain aesthetic decoration. This is the most economical way to fire.. The cast-in-place solid concrete cladding is usually reinforced with steel mesh or steel to limit shrinkage cracks and to ensure the strength of the outer casing.

　　3. It adopts seamless steel pipe fireproof coating protection component. Outsourcing layer. Shielded. As a result, they cannot be used due to excessive deformation.Seamless steel tubes usually lose their load carrying capacity at temperatures of 450 to 650 °C, causing large deformations, resulting in bending of steel columns and steel beams. The sand pump can be lime cement or gypsum mortar, or can be mixed with perlite or asbestos. Generally the fire resistance limit of unprotected seamless steel tubes is about 15 minutes. In the event of a fire accident in a high-rise building, the fire will not be extinguished in a short period of time. At the same time, the outer layer can also be made of perlite, asbestos, gypsum or asbestos cement, light concrete, and fixed on the seamless steel pipe with adhesive, nails and bolts. The heated water can be recirculated after cooling, or cold water can be introduced from the pipeline to replace the heated water. Filling the hollow seamless steel pipe is the most effective protection against fire.

The length of this time is also related to the speed at which the component absorbs heat. The seamless steel pipe is placed in the wall or ceiling of stainless steel shower handrial the refractory material, or the component is hidden in the space between the two walls, and the fireproofing purpose can be achieved by adding a little refractory material or increasing it. Program to reduce casualties and property damage. The spraying method can apply a sand pump to the surface of the seamless steel pipe at the construction site to form a protective layer. Function, belonging to modern advanced fire prevention technical measures. It is to add an outer layer on the outer surface of the seamless steel pipe, which can be cast in place or sprayed.

　　At present, high-rise seamless steel pipe construction is increasing, especially for some super high-rise buildings, which use a wider range of seamless steel pipe materials. Filled with water. Expanded materials. This requires us to increase the fire protection of the building materials during the design of the building to enhance its fire resistance and to develop the necessary emergency within the building.

    This method enables the seamless steel pipe to maintain a lower temperature in the fire, and the water circulates in the seamless steel pipe to absorb the heat of the material itself
