As is well known, plastic coated steel pipes can not only be used in the fields of water supply and drainage, but also in automatic sprinkler fire extinguishing systems, underground water and sewage trench pipes, central air conditioning cooling and circulating water pipes, and cables. Screw protection pipes and industrial corrosion-resistant pipelines, underground coal mine gas extraction, ventilation pipes, oil and natural gas transmission pipelines, etc. These fields are gradually deepening with the continuous improvement of technological level.

Plastic coated steel pipes used for water supply have the strength of steel pipes, but also have the advantages of corrosion resistance, wear resistance, and low fluid resistance of plastic pipes. They are a new type of water supply pipeline. It improves the defects of galvanized pipes, such as easy rusting, production of yellow water, blockage caused by small pipe diameter and scale accumulation, which has a significant impact on preventing secondary pollution and improving water quality.

Specific applications of plastic coated steel pipes
1. Various forms of circulating water supply systems (civilian circulating water, industrial circulating water) have excellent performance, and the corrosion resistance life of plastic coated steel pipes can reach 50 years. Heating network transportation system, underground heating network transportation system, cold and hot circulating water supply system. The use of special plastic coated pipes for central air conditioning water flow systems can expand the pipeline and improve the service life of equipment, and can be energy-saving and environmentally friendly, ensuring long-term stable operation of central air - regulating the water supply system, and greatly reducing the later maintenance costs of central air conditioning systems.

2. Fire water supply system. The characteristics of water used in fire prevention and sprinkler systems are long-term stagnation and sudden emergency use. The inner surface of ordinary steel pipes is easy to expand. During emergency use, the internal diameter of the pipeline may be reduced or blocked by the internal structure of the pipeline, delaying disaster relief and resulting in catastrophic consequences. Professional anti plastic coated steel pipes use flame adhesive resin, which has good high-temperature resistance. They focus on solving the corrosion of fire extinguishing agents, as well as their corrosion resistance and fire resistance in the presence and absence of water, greatly improving the fire water supply and automatic sprinkler systems. The service life of the shower pipe system. It increases the value of the system and reduces the overall cost of pipeline maintenance.

3. Water supply and drainage transportation for each building (especially suitable for cold water systems in hotels, hotels, and high-end residential areas). Large diameter plastic coated steel pipes use steel pipes as bottom pipes. Under the premise of being able to fully withstand design pressure, relatively thin basic pipelines can be selected, greatly reducing the procurement cost for users. Its excellent cost performance competes in the field of large-diameter water supply and drainage. Strength.
4. Transportation of various chemical liquids (resistant to acid, alkaline, and salt corrosion). Industrial chemical industry: corrosive medium-sized transportation in the petrochemical industry, non productive metal smelting, coking, light industry, and other industries. Industrial plastic coated steel pipes for corrosion resistance are mainly used for the transportation of acids, alkalis, salt liquids, and various chemical substances, as well as for factories in petrochemical, power, light industry, and other industries without water.
5. Buried pipelines and pipelines for wires and cables. The internal and external anti-corrosion cable protective sleeves are smooth and have strong chemical stability and corrosion resistance, good mechanical properties, and high compressive strength. Plastic coated steel pipes play an excellent role in protecting cables and are suitable for both high and low applications. Cable threads. Sockets can be used for pipeline connections, which facilitates on-site use.
6. Ventilation pipes, water supply and mine drainage pipes. Coal mine system: underground water supply and drainage, fire sprinklers, underground shotcrete, positive and negative pressure ventilation and gas drainage, and other pipeline networks.
7. Municipal system: Anti corrosion pipelines (such as building water supply, natural gas, seawater transportation, and sewage discharge) require plastic coated steel pipes.
8. Protection items: Buried cable protection pipes, fire protection pipeline systems, sports field and kindergarten guardrail projects.
9. Other corrosion-resistant pipes suitable for plastic coated steel pipes.
