1. Outer cladding. It is to add an outer cladding on the surface of the seamless steel pipe, which can be cast or sprayed on site. The cast-in-place solid concrete outer cladding is usually reinforced with wire mesh or rebar to limit shrinkage cracks and ensure the strength of the shell. This spraying method can apply a sand pump on the surface of the seamless steel pipe at the construction site to form a layer. Sand pumps can be lime cement or gypsum mortar, or mixed with perlite or asbestos. At the same time, the outer cladding can also be made of perlite, asbestos, gypsum or asbestos cement and lightweight concrete into prefabricated panels, which are then fastened to seamless steel pipes with adhesives, nails and bolts.

2. Add water. . Water injection into hollow seamless steel pipes is an effective fire prevention measure. This method can keep the seamless steel pipe at a low temperature in the fire, the water circulates in the seamless steel pipe, and absorbs the heat of the material itself. The hot water can be recirculated after cooling, or cold water can be piped in in place of the hot water.

3. Set up the shield. Seamless steel pipes are installed in walls or ceilings made of refractory material, or parts are hidden in gaps between two walls. As long as a small amount of refractory material is added or not added, the purpose of fire prevention can be achieved. This is a very economical method of fire protection.

 4. Expansion materials. Using seamless steel pipe fireproof coating composition, this method has the advantages of good fire resistance, construction is not limited by the geometric shape of seamless steel pipe, generally does not add auxiliary facilities, and the coating quality is light, but also has a certain decorative effect, it belongs to modern Advanced fire protection technology measures.
