1. Set up the external insulation layer.
It is to add the outer layer on the surface of seamless steel pipes through the casting or spray paint method. The cast-in-place solid concrete layer is usually reinforced with steel mesh or reinforcement bar to limit shrinkage cracks and ensure the strength of the shell. While the sprayed way is used to utilize sand pumps to form a protective layer on the surface of seamless steel pipes at the construction site. The sand pump can be lime, powdery gypsum or be mixed with perlite or asbestos. In addition, the external insulation layer can also use the prefabricated panels made of perlite, asbestos, plaster and asbestos concrete and fixed with adhesive, steel pins and anchor bolts.
2. Inject water.
Water injection is an effective protection against fire because seamless steel pipes own hollow cross-sections. This method is capable of making seamless steel pipes maintain a relatively low temperature in the fire accident. Water circulates in the pipe, absorbing the heat of the material itself. What’s more, the water in the heat can be circulated again after being cooled, and it is feasible to reintroduce cold water to replace the hot water.
3. Isolate.
Seamless steel pipes can be installed in the wall or ceiling composed of fire-resistant materials or be hidden in the gap between the two walls. It seems to be a kind of economic fire prevention measure that the purpose of fire safety can be achieved if little fire-resistant materials are added or even not added.
4. Utilize coating materials.
We can apply coating materials with excellent fire-proof and secure characteristics to maintain the component of seamless steel pipes. And the construction process will not be restricted by the shape of pipes and do not need the assistance of ancillary equipment. The coating is light and also processes certain aesthetic and decorative effects for the housing.
Nowadays, the number of high-rise residential with seamless steel pipe constructions is increasing day by day. Particularly, there are more and more multi-story buildings applying seamless steel pipes. However, if a fire accident occurs in that building, it is unlikely to put out the fire in a short period of time. At this time, we ought to pay attention to the fire prevention of building decorating materials when planning and designing so as to improve the fire-resistant capability. And we also need to develop the necessary replied measures for the construction to reduce unnecessary losses in property and human lives.
