Seamless steel pipe will generally lose the bearing capacity at 450~650℃ temperature, producing a very large deformation, resulting in steel beam, and steel column bending, the result of the deformation is too large and can not be used again, generally does not need to maintain the seamless steel pipe fire rating for 15 minutes. The length of this time is also related to the heat absorption reaction rate of the prefabricated components. The fire safety measures of several different types of seamless steel pipes are described in detail below.

1. External insulation layer. 

It is to add an external insulation layer on the surface of the seamless steel pipe, which can be cast and formed and can also be sprayed. The external insulation layer of the solid line concrete is generally raised with steel wire mesh or construction steel bars to limit the gap and ensure the compressive strength of the house. The construction site can be sprayed on the surface of the seamless steel pipe to form a protective layer. Sediment pumps can be lime-powder concrete, painted plaster, or mixed with pottery or asbestos. In addition, the external insulation layer can also be made of ceramic materials, asbestos, plaster of paris or asbestos concrete, lightweight concrete cement prefabricated panels, adhesives, steel nails, and anchor bolts used to fix the seamless steel pipe.

2. Water injection. 

Water injection of hollow seamless steel pipes is a reasonable protection measure to prevent fire accidents. This method can keep the seamless steel pipe at a low temperature in a fire accident, and the water circulation in the seamless steel pipe car can digest and absorb the heat of the raw material itself. The heated water is cooled and recycled, or cold water is introduced into the pipes to replace the heated water.

3. Block it. 

Seamless steel pipes are set in walls or roofs made of refractory insulation, or prefabricated elements are hidden in the gap between two walls. Only a small amount of refractory insulation material or no hoisting can achieve the purpose of fire safety. This is a very economical way to develop fire safety.

4. Pengzhang raw materials. 

Choose prefabricated seamless steel pipe fire protection materials for maintenance, this method has the advantages of good fire safety and fire resistance, engineering construction is not limited by the geometry of seamless steel pipes, generally, there is no need to add auxiliary equipment, and the coating quality is light, and there are some beautiful decorations The design effect belongs to the contemporary excellent fire safety technical measures.

At present, the construction of seamless steel pipes for high-rise residential buildings is increasing, especially in some multi-story buildings, the choice of raw materials for seamless steel pipes is more common. In the event of a safety accident in a multi-story building, the fire cannot be eliminated in a short period of time. This requires us to increase the fire safety maintenance of building decoration materials in the architectural planning and design to improve the fire protection level. measures to reduce casualties and economic losses.
