Characteristics of plastic-coated steel pipes for mining

Plastic-coated steel pipes designed for mining applications combine the durability of steel with the safety and corrosion resistance of specialized coatings. These pipes are essential for the harsh and demanding conditions of mining environments, offering the following key characteristics:

1. Flame Retardant and Anti-Static

The pipes use a polyethylene coating specifically formulated for mining applications. The anti-static and flame-retardant components are evenly distributed across both the inner and outer layers. This ensures compliance with the MT181 standard, making the pipes suitable for flammable and explosive underground environments in mines.

2. Exceptional Adhesion

The coatings on both the inner and outer surfaces bond and solidify with high strength, achieving an adhesion force of≥30 N/10 mm. This robust adhesion allows the pipe to withstand impacts and tearing from falling objects without damage.

3. Corrosion Resistance and Low Scaling Potential

These pipes exhibit strong resistance to acids, alkalis, and corrosion, making them ideal for handling high-sulfur water and water containing ions like calcium and magnesium in coal mines. Their smooth inner surfaces prevent scaling, reduce fluid resistance, and minimize secondary pollution.

4. High Pressure Tolerance

The polyethylene powder coating provides excellent toughness, while the steel pipe’s mechanical strength enables it to endure high pressure and external stresses, such as impact and bending, without compromising performance.

These characteristics make plastic-coated steel pipes an optimal choice for mining operations, ensuring safety, durability, and efficiency in challenging underground environments.
