Galvanized Exterior & Epoxy Coated Interior
Composite Steel Pipe for Water Supply
Product Introduction:
After coating the surface of the steel pipe with an epoxy resin layer, the pipe combines the advantages of both steel and plastic. It features high mechanical strength, good heat resistance, excellent electrical insulation, strong stability, firm coating adhesion, and low curing shrinkage. The externally galvanized, internally epoxy resin-coated composite steel pipe for water supply uses hot-dip galvanized steel pipe as the base. The inner wall is coated with epoxy powder that is specially approved by the Ministry of Health for hygiene and safety in drinking water applications, making this pipeline material specifically designed for the transport of domestic drinking water.
Product Features:
- Strong Corrosion Resistance: The epoxy resin coating effectively resists corrosion from various acidic, alkaline, and saline media, making it suitable for a wide range of corrosive environments.
- Good Mechanical Properties: The coated pipe has high strength and rigidity, capable of withstanding certain external forces. Additionally, the epoxy coating bonds tightly with the metal pipe, allowing the pipe to endure stress variations caused by pressure and temperature changes during operation.
- Excellent High-Temperature Resistance: Some epoxy resin pipe variants can be used under high-temperature conditions, withstanding temperatures up to 200°C or higher, making them suitable for high-temperature working environments.
- Environmentally Safe: Epoxy resin coatings produce no harmful substances during the curing process. The coating is non-toxic, harmless, and environmentally friendly, causing no pollution to water quality.
- Easy Installation: Compared with traditional metal pipes, this type of pipe is lighter in weight and can be connected in multiple ways—such as socket connections, hot-melt welding, or flange connections—offering more convenience during installation.
Product Applications:
- Municipal Engineering: Used in urban water supply, drainage, and gas transport pipelines. Epoxy resin coated steel pipes are suitable for domestic water supply and drainage systems.
- Construction Industry: Applicable to indoor and outdoor water supply and drainage systems, and fire protection systems. The aesthetic appearance and reliable performance meet functional needs while enhancing building quality.
- Power Industry: Used in power plant circulating water systems and electric cable protection pipelines.
- Environmental Protection Facilities: Used in wastewater treatment equipment and sewage discharge pipelines. With their anti-corrosion, wear-resistant, and anti-aging characteristics, they significantly extend the service life and performance of facilities.
