There are generally 5 types of fire pipes. They are: ductile iron water supply pipes, copper pipes, alloy pipes, composite pipes, and plastic pipes. Fire pipes refer to pipe materials used for fire protection, connecting fire protection equipment and equipment, and transporting fire extinguishing water, gas and other media.
Due to special requirements, there are special requirements for the thickness and material of fire-fighting pipes, and they are sprayed with red paint to transport fire-fighting water. Since fire protection pipelines are often in a static state, the requirements for pipelines are more stringent. Pipes need to be resistant to pressure, corrosion, and high temperature.
Fire pipe categories:
1. Alloy pipe
Metal pipes are a relatively common fire protection pipe material, including cast iron pipes,
galvanized steel pipes,
stainless steel pipes and other materials. Alloy pipe is a kind of
seamless steel pipe. Its performance is much higher than that of ordinary seamless steel pipe. Because steel pipe contains higher Cr, its high temperature, low temperature, corrosion resistance and pressure resistance are stronger than other seamless steel pipes. Therefore, alloy pipe Widely used in fire protection systems of large buildings and public facilities. At the same time, it is also widely used in petroleum, aerospace, chemical industry, electric power, boiler, military industry and other industries. However, the disadvantages of metal pipes are also obvious, such as easy rusting, heavy weight, and high installation costs.
2. Plastic pipes
As an important part of chemical building materials, plastic pipes have the characteristics of good performance, hygiene, environmental protection, and low loss. Widely used by users, the main products include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, PE water supply pipes, etc. Plastic pipes are corrosion-resistant, lightweight, simple to install, and have a long service life. However, the pressure-bearing capacity of plastic pipes is poorer than that of metal pipes, so the scope of application will be limited.
3. Fiberglass pipes
FRP pipes are pipes made of fiberglass and resin composite materials. They are corrosion-resistant, anti-aging, and easy to install. They are suitable for some special scenes, such as chemical laboratories, hospital operating rooms, food production workshops, etc. However, due to the high manufacturing cost, the use range of FRP pipes is relatively narrow.
4. Composite pipe
Composite pipes are made of a variety of materials and can be selected according to actual needs. Composite pipes not only take into account the advantages of various materials, but also avoid the shortcomings of various materials, such as noise reduction, heat resistance, corrosion resistance, lightweight and other characteristics. It is a relatively popular fire pipe material in recent years.
To sum up, there are many types of materials for fire protection pipes. Different materials are suitable for different scenarios. Choosing the appropriate material can ensure the effectiveness and safety of fire protection facilities.
