How to Choose High-Quality Plastic-Coated Steel Pipes

First, what are plastic-coated steel pipes?

Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, or plastic-coated composite steel pipes, are steel-plastic composite pipes with a steel pipe base. A layer of plastic anti-corrosion coating is fused to the inner surface of the steel pipe through spraying, rolling, dipping, or suction processes, or to both the inner and outer surfaces. Plastic-coated steel pipes have excellent corrosion resistance and relatively low frictional resistance. Epoxy resin-coated steel pipes are suitable for conveying media such as water supply and drainage, seawater, warm water, oil, and gas. Polyvinyl chloride (PVC)-coated steel pipes are suitable for conveying media such as drainage, seawater, oil, and gas.

Second, what are the product characteristics of plastic-coated steel pipes?

1. Plastic-coated steel pipes are hygienic and non-toxic, do not accumulate scale, do not breed microorganisms, and ensure fluid quality.

2. Plastic-coated steel pipes are more resistant to chemical corrosion, soil and marine organism corrosion, and cathodic disbondment.

3. The installation process for plastic-coated steel pipes is mature, convenient, and quick.

4. Plastic-coated steel pipes have good weather resistance and are suitable for harsh environments such as deserts and saline-alkali lands.

5. Plastic-coated steel pipes have smooth walls, improving transportation efficiency and extending service life.

Thirdly, what are the advantages of plastic-coated steel pipes for water supply?

Advantages of plastic-coated steel pipes for water supply: They possess the strength, ease of connection, and resistance to water flow impact of steel pipes, while overcoming the disadvantages of steel pipes, such as susceptibility to corrosion, pollution, and scaling when exposed to water, and the low strength and poor fire resistance of plastic pipes.

Fourth, Epoxy Resin Coated Steel Pipe Connection Methods:

Threaded connection: DN15-DN100;

Grooved connection: DN65-DN400;

Bimetallic welded connection: DN100-DN800;

Flange connection: Applicable to any diameter.Welded connection: Applicable to any diameter.

Fifth, Application Scope of Double-Sided Plastic-Coated Steel Pipes:

1. Double-sided plastic-coated steel pipes are used in fire sprinkler systems and domestic water supply and drainage.

2. Double-sided plastic-coated steel pipes are used in gas extraction, slurry transportation, and ventilation systems in coal mines;

3. Double-sided plastic-coated steel pipes are used as chemical corrosion-resistant pipelines, which can be buried underground and transport media containing acids, alkalis, and other corrosive substances without reducing pipeline lifespan.

4. Double-sided plastic-coated steel pipes are used for the protection of communication cables, and are widely used in cable renovation projects in major urban and rural areas.

5. Double-sided plastic-coated steel pipes are used in central air conditioning and HVAC circulating water systems. Using this pipeline ensures the normal operation of the central air conditioning water circulation system.
