Hot-dipped galvanized steel pipe composite can be used in coal mine gas extraction, ventilation systems, fire-fighting water supply systems, central air conditioning heating, ventilation, and air conditioning circulating water pipelines, industrial water supply and drainage, domestic water supply and drainage, gas transmission for other gases, power line routing, chemical industry conveying pipelines, and seawater treatment pipes, etc.

High-temperature immersion coated steel pipes offer excellent antistatic properties: By adding antistatic agents to the formula, the surface resistance of both the inner and outer surfaces reaches and exceeds the national industry standards, ≤1×10Ω.

2. Heat-impregnated steel pipe flame-retardant performance: The product uses plastic raw materials enhanced with flame-retardant additives. Its flame-retardant performance meets national standards, and its steel-plastic composite structure offers superior flame-retardant properties compared to pure plastic pipes, making it suitable for underground environments prone to flammability and explosive hazards.

3. Hot Dip Galvanized Steel Pipe Coating Adhesion: The steel pipe surface is treated with a special process, achieving a coating adhesion of ≥30N/10mm after curing.

4. Dense inner and outer resin layers: Coating thickness of over 0.5 mm, with pinholes and excellent corrosion resistance.

5. The superior mechanical properties of hot-dipped galvanized steel pipes: Capable of withstanding stringent usage conditions; the coating exhibits excellent toughness, and the pipes have high mechanical strength, demonstrating strong resistance to external impacts such as shock and bending, far outperforming other mining plastic pipes in terms of performance.

6. Hot-dip galvanized steel pipes offer corrosion resistance, non-scaling, and low fluid resistance: They are suitable for transporting high-sulfur water and water containing calcium, magnesium ions underground, saving maintenance costs, and have a significantly longer service life than other pipe materials, with high overall economic benefits.

7. Self-lubricating: The inner wall is smooth and non-scaling, resulting in lower conveying resistance. Under the same conditions, it can improve conveying capacity by 30%.

8. Overcoming the difficulty of connecting pure plastic mining materials, the product offers convenient and reliable connections. It can be connected to the existing steel pipes and valves underground using flanges, quick couplings, and other accessories, providing strong interchangeability.
