Fire protection measures for seamless carbon steel pipes.

Seamless carbon steel pipes generally lose their bearing capacity at a temperature of 450~650°C, resulting in very large deformations, causing steel beams and columns to bend, resulting in excessive deformation that cannot be used again. Generally, no maintenance is required for seamless carbon steel pipes The fire rating is 15 minutes. The length of this period is also related to the endothermic reaction speed of the prefabricated components. The fire protection measures of several different types of seamless carbon steel pipes are introduced in detail below.

1. Outer insulation layer.

It is to add an external insulation layer on the surface of the seamless steel pipe, which can be cast or painted. The outer insulation layer of cast-in-place solid concrete is generally heightened by steel wire mesh or building steel bars to limit the gaps and ensure the compressive strength of the house. On the construction site, spray paint can be used on the surface of the seamless steel pipe to form a protective layer. Sand pumps can be lime-powdered concrete or painted plaster, or they can be mixed with clay or rock wool. In addition, ceramic materials, rock wool, plaster of paris or rock wool concrete can also be used for the external insulation layer, and lightweight concrete cement prefabricated panels are fixed on seamless steel pipes with adhesives, steel nails, and anchor bolts.

2. Water injection.

Water injection of hollow seamless steel pipe is a reasonable fire protection measure. This method can keep the seamless steel pipe at a low temperature in the event of a fire, and the water circulates in the seamless steel pipe car to digest and absorb the heat of the raw material itself. The heated water can be recycled after being cooled, and cold water can also be introduced in the pipeline to replace the heated water.

3. Block it.

The seamless steel pipe is set in the wall or roof made of refractory insulation material, or the prefabricated component is hidden in the gap between the two walls. Only a small amount of fireproof insulation material or no hoisting can achieve the purpose of fireproofing. This is a very economical way of developing fire safety.

4. Raw material of Pengzhang.

Choose prefabricated seamless steel pipe fireproof material maintenance, this method has good fire safety and fireproof performance, engineering construction is not subject to the advantages of seamless steel pipe geometry, generally do not 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 high-rise residential seamless steel pipes is increasing, especially in some multi-storey buildings, the selection of seamless steel pipe raw materials is more common. Once a safety accident occurs in a multi-storey building, the fire cannot be extinguished in a short time, which requires us to increase the fire protection of building decoration materials in architectural planning and design to improve the fire resistance level, and formulate necessary countermeasures inside the engineering building , to reduce casualties and economic losses.
