As we all know, in addition to being used in the field of water supply and drainage, plastic-coated steel pipes can also be well used in the field of automatic sprinkler fire extinguishing systems, groundwater sewage dredging pipelines, central air conditioning cooling circulating water pipelines, cable threading protection pipes, industrial anti-corrosion pipelines, coal mine underground gas extraction, ventilation pipelines, oil and natural gas pipelines, etc. These fields are also gradually deepening with the continuous improvement of technical levels.
Plastic-coated steel pipes for water supply have the strength of steel pipes, and at the same time have the advantages of plastic pipes such as corrosion resistance, wear resistance, and low fluid resistance. It is a new type of water supply pipeline. It improves the defects of galvanized pipes that are easy to rust, produce yellow water, and cause small pipe diameters and blockages due to scale accumulation, which has a significant effect on preventing secondary pollution and improving water quality.
Specific applications of plastic-coated steel pipes
1. Various forms of circulating water systems (civilian circulating water, industrial circulating water), with excellent performance, the anti-corrosion period of plastic-coated steel pipes can reach 50 years. Heat network water supply system Buried heat network water supply, hot and cold circulating water system. The use of plastic-coated special pipes for the central air-conditioning water circulation system can extend the service life of the pipeline and equipment, and is energy-saving and environmentally friendly, ensuring the long-term stable operation of the central air-conditioning water system, while greatly reducing the cost of later maintenance of the central air-conditioning system.
2. Fire water supply system. The characteristics of water used in fire-fighting and sprinkler systems are long-term static and sudden emergency use. The inner surface of ordinary steel pipes is prone to scaling. When used in an emergency, the internal structure will reduce or block the inner diameter of the pipe, delaying disaster relief, and the consequences are disastrous. Professional fire-fighting plastic-coated steel pipes use flame-retardant epoxy resins, have good high-temperature resistance, focus on solving the corrosion of fire extinguishing agents, as well as anti-corrosion and flame resistance in water and waterless states, greatly improving the service life of fire-fighting water supply and automatic sprinkler pipe systems. It improves the value of the system and reduces the comprehensive cost of pipeline maintenance.
3. Water supply and drainage transportation of various buildings (especially suitable for cold and hot water systems in hotels, hotels, and high-end residential areas). Large-diameter plastic-coated steel pipes use steel pipes as base pipes. Relatively thin base pipes can be selected under the premise that they can fully withstand the design pressure, which greatly reduces the user's procurement cost. Its excellent cost-effectiveness is competitive in the field of large-diameter water supply and drainage.
4. Various chemical fluid transportation (acid, alkali, and salt corrosion resistance). Industrial chemical industry Corrosive medium transportation in petrochemical, non-ferrous metal smelting, coking, light industry, and other industries. The main users of industrial plastic-coated steel pipe anti-corrosion pipelines are acid, alkali, salt liquid, and various chemical and waterless transportation in factories in petrochemical, electric power, light industry, and other industries.
5. Buried pipes and crossing pipes for wires and cables. The cable protection sleeves inside and outside the cable are smooth and smooth inside, with strong chemical stability and corrosion resistance, good mechanical properties, and high compressive strength. The plastic-coated steel pipe plays a very good protective role for the cable and is suitable for high and low cable threading. The pipe connection can be made in a socket-and-spigot manner, which is convenient for on-site use.
6. Ventilation pipes, water supply, and drainage pipes in mines and mines. Coal mine system: underground mine water supply and drainage, fire sprinkler, underground grouting, positive and negative pressure ventilation, and gas extraction pipe network.
7. Municipal systems building water supply, natural gas, seawater transportation, sewage, and other anti-corrosion pipes need to use plastic-coated steel pipes.
8. Protective engineering buried cable protection pipes, fire sprinkler pipe systems, and sports field kindergarten guardrail projects.
9. Other anti-corrosion pipes suitable for plastic-coated steel pipes.
