What are the applications of plastic-coated steel pipes

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 pipes, central air-conditioning cooling circulating water pipes, cable threading protection pipes, industrial anti-corrosion pipes, Underground coal mine gas pumping, ventilation pipelines, oil and gas pipelines, these fields are also gradually deepening with the continuous improvement of the technical level. Plastic-coated steel pipes for water supply have the strength of steel pipes, and at the same time have the advantages of corrosion resistance, wear resistance, and small fluid resistance of plastic pipes. They are a new type of water supply pipeline. Improve the defects of galvanized pipes that are easy to rust, produce yellow water, and fouling cause small pipe diameters, blockages, etc., and have a significant effect on preventing secondary pollution and improving water quality.

Specific application of plastic-coated steel pipe

1. Various forms of circulating water systems (civil circulating water, industrial circulating water) have excellent performance, and the anti-corrosion life of plastic-coated steel pipes can reach 50 years. Heat network water delivery system Buried heating network water delivery, hot and cold circulating water system. The use of plastic-coated special pipes for the central air-conditioning water circulation system can extend the pipeline and improve the service life of the equipment, and it is energy-saving and environmentally friendly, ensuring the long-term stable operation of the central air-conditioning water system, greatly reducing the later maintenance costs of the central air-conditioning system.

2. Fire water supply system.

The characteristics of water for firefighting and sprinkler systems are long-term static and sudden emergency use. The inner surface of ordinary steel pipes is prone to fouling. When emergency use is closed, the internal structure will reduce or block the inner diameter of the pipe, delaying disaster relief, and the consequences are unimaginable. The professional fire-fighting plastic-coated steel pipe adopts flame-retardant epoxy resin, which has good high-temperature resistance. the service life of the sprinkler system. 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 the base pipe. Under the premise that they can fully withstand the design pressure, a relatively thin base pipe can be selected, which greatly reduces the purchase cost of users. Its excellent cost performance competes in the field of large-diameter water supply and drainage. force.

4. Various chemical fluid transportation (acid, alkali, salt corrosion).

Industrial chemical industry Corrosive medium transportation in petrochemical, non-ferrous metal smelting, coking, light industry, and other industries. Industrial plastic-coated steel pipe anti-corrosion pipelines are mainly used for the transportation of acids, alkalis, salts, various chemicals, and anhydrous in factories in petrochemical, electric power, and light industries.

5. Underground pipes and passage pipes for wires and cables.

The inner and outer anti-corrosion cable protection sleeves of the cables are smooth and smooth inside, have strong chemical resistance and corrosion resistance, good mechanical properties, high compressive strength, and plastic-coated steel pipes play a very good role in protecting the cables. They are suitable for high and low Cable threading. The pipe connection can be socketed, which is convenient for on-site use.

6. Ventilation pipes, supply and drainage pipes of mines and mines. Coal mine system Underground water supply and drainage, fire sprinkler, underground grouting, positive and negative pressure ventilation, gas drainage, and other pipe networks.

7. Municipal system Anti-corrosion pipelines such as building water supply, natural gas, seawater transmission, and sewage discharge need to use plastic-coated steel pipes.

8. Protection engineering Buried threading cable protection pipe, fire sprinkler pipeline system, playground kindergarten guardrail project.

9. Other anti-corrosion pipes suitable for plastic-coated steel pipes.
