In today's urban construction, the fire water supply system is one of the important facilities to ensure the safety of people's lives and property. As an important part of the system, the quality and performance of the pipe for fire water supply are directly related to the reliability and safety of the entire fire protection system. In order to meet this demand, a new type of composite plastic-coated steel pipe for fire water supply came into being, which adopts the coating structure of outer PE and inner EP, which has good corrosion resistance and environmental protection performance, and is widely used in buried fire water supply system.
1. Characteristics of composite plastic-coated steel pipes for fire water supply.
The composite plastic-coated steel pipe for fire water supply is made of high-quality seamless steel pipe as the base material, which is covered with a layer of polyethylene (PE) coating on the surface and epoxy powder (EP) on the inside. This special coating structure gives the steel pipe excellent corrosion resistance, environmental performance and service life. Compared with traditional galvanized steel pipes, composite plastic-coated steel pipes can have a service life of up to 50 years, reducing the hassle and cost of frequent pipe replacement. In addition, the coating material of the steel pipe is non-toxic and tasteless, harmless to the human body, and will not pollute the water quality, in line with the relevant national environmental protection standards.
Second, the advantages of composite plastic-coated steel pipes for fire water supply.
1.Strong corrosion resistance: Due to the excellent performance of the coating material, the composite plastic-coated steel pipe can effectively resist the corrosion of acids, alkalis, salts and other chemicals, which greatly reduces the risk of leakage due to corrosion of the pipeline.
2.Good environmental performance: the coating material is non-toxic and tasteless, will not cause pollution to the environment, and also avoids secondary pollution caused by pipeline corrosion.
3.Fire water supply system is safe and reliable: Because the composite plastic-coated steel pipe has excellent corrosion resistance and environmental protection performance, it can ensure the long-term stable operation of the fire water supply system and improve the reliability and safety of the fire water supply system.
4.Easy installation: The connection mode of composite plastic-coated steel pipe is simple and reliable, which can effectively shorten the construction period and reduce the construction cost. At the same time, the steel pipe is lightweight, easy to install and maintain.
5.Long service life: Because the composite plastic-coated steel pipe uses high-quality seamless steel pipe as the base material, it can be used for up to 50 years after the internal and external plastic coating process, which reduces the trouble and cost of frequent pipe replacement.
3. The application range of composite plastic-coated steel pipes for fire water supply.
As a new type of pipe for fire water supply system, composite plastic-coated steel pipe is widely used in buried fire water supply system on various occasions. For example: outdoor fire water supply pipe network and indoor fire hydrant pipe network in residential quarters, commercial buildings, public buildings, industrial parks and other places. The steel pipe has excellent corrosion resistance and environmental performance, which can ensure the long-term stable operation of the fire water supply system and provide a strong guarantee for fire safety in various places.
Fourth, summary. With the continuous acceleration of urbanization and the continuous improvement of people's awareness of fire safety, the requirements for fire water supply systems are also getting higher and higher. As a new type of pipe for fire water supply system, the composite plastic-coated steel pipe for fire water supply has the advantages of strong corrosion resistance, good environmental performance, safe and reliable fire water supply system, easy installation and long service life. The steel pipe has a wide range of applications and can meet the fire safety needs of various places. With the continuous progress of technology and the continuous expansion of the application range, composite plastic-coated steel pipes will become one of the important development directions of the fire water supply system in the future.
