Performance features of PE coated steel pipe

PE-coated steel pipes are composite pipes designed to combine the durability of steel with the protective properties of polyethylene (PE) coating, offering exceptional anti-static, flame retardant, and anti-corrosion performance. This innovative product overcomes the typical drawbacks of other pipe materials, such as corrosion, rust, deformation, and the low strength of plastic pipes. By integrating the strengths of both steel and plastic, PE-coated steel pipes have become a key solution for energy savings and environmental protection in modern industries.

Performance Features of PE Coated Steel Pipes:

- Outstanding Mechanical Properties:
PE-coated steel pipes leverage the inherent strength and pressure-resistance of steel, making them highly durable and capable of withstanding external impacts, making them ideal for a range of demanding applications.

- Superior Chemical Resistance:
The polyethylene coating provides excellent resistance to chemical corrosion, allowing the pipes to safely transport fluids containing sulfur, calcium, magnesium, and other corrosive substances. This makes PE-coated steel pipes especially suitable for underground mining operations and industries that deal with aggressive chemicals. Additionally, after anti-corrosion treatment, these pipes can be equipped with various fittings such as flanges, tees, and elbows, ensuring uniform corrosion protection across the entire system.

- Strong Coating Adhesion:
The composite pipe undergoes special physical treatment, with surface preparation meeting the Sa 2.5 standard. This advanced process guarantees that the coating adheres strongly to the steel, ensuring long-lasting performance that exceeds national standards.

- Smooth Internal Surface:
The pipe's internal surface is coated with a dense layer, eliminating issues like scaffolding and scaling. The smoothness of the internal coating results in a reduced friction coefficient and a lower roughness compared to conventional steel pipes, improving the efficiency of fluid transportation.

- Flame Retardant and Antistatic:
The polyethylene or epoxy powder coating used on these pipes is not only antistatic but also flame-retardant. This specialized coating is evenly distributed on both the inner and outer surfaces of the pipe, providing enhanced safety in environments prone to electrical hazards or fire risks.

- Simple Installation:
PE-coated steel pipes feature various connection methods such as quick joints and flanges, ensuring a simple and reliable installation process. These user-friendly connections help save time and labor while maintaining the integrity of the system.

- Customizable Flexibility:
The coatings on PE-coated steel pipes can be tailored to meet specific user requirements, with various materials and colors available for both internal and external coatings. Common configurations include internal and external polyethylene coatings, internal and external epoxy coatings, and combinations of the two. This versatility allows the product to adapt to a wide range of applications and environmental conditions.

- Enhanced Anti-Corrosion (3PE Coating):
The optional 3PE (Triple Layer Polyethylene) coating provides an enhanced level of corrosion resistance. The high-density polyethylene compounding material offers excellent electrical properties, environmental stress crack resistance, UV light aging resistance, heat aging resistance, and resistance to various chemicals, ensuring superior long-term performance in challenging conditions.
