Pipe Surface Treatment: Protecting Your Investment

At Baolai Steel Pipe, we know that the longevity and performance of steel pipes depend on their protection against corrosion and environmental factors. Our Pipe Surface Treatment services provide a durable shield, ensuring your pipes withstand harsh conditions and deliver reliable performance for decades. We apply a variety of advanced coatings to meet the specific demands of your project.

Painting

Purpose: To provide a protective layer against rust and corrosion while also allowing for color-coding for identification.

Processing Technology: We apply a durable layer of paint, commonly in Black, Red, or Clear Varnish.

Benefits:

  • Corrosion Protection: Forms a barrier that protects the steel from moisture and rust.
  • Customization: We can customize the color to meet your project’s specific needs, such as yellow for gas pipelines or red for fire pipelines, enhancing safety and organization.
  • Aesthetics: Provides a clean and finished look for visible installations.

Oiling

Purpose: To provide a temporary protective film that prevents rust during storage and transport.

Processing Technology: A thin layer of protective oil is applied to the pipe’s surface, creating a moisture-resistant barrier.

Benefits:

  • Rust Prevention: Effectively prevents surface rust and oxidation before the pipe is installed or coated with a more permanent solution.
  • Cost-Effective: An economical way to protect pipes in transit or short-term storage.
  • Easy Application: Can be applied quickly and is suitable for a wide range of steel pipes.

Galvanizing

Purpose: To provide a highly durable and long-lasting zinc coating for superior corrosion resistance.

Processing Technology: Pipes are submerged in a bath of molten zinc, creating a metallurgical bond between the zinc and the steel.

Benefits:

  • Superior Corrosion Resistance: Offers exceptional protection from rust, even in highly corrosive environments.
  • Strong Adhesion: The coating is bonded to the steel, making it highly resistant to chipping, peeling, and flaking.
  • Long Service Life: Provides decades of protection, significantly extending the life of the pipe with minimal maintenance.

FBE Coating

Purpose: A high-performance thermoset coating that provides excellent corrosion protection for steel pipes.

Applicable Temperature: Suitable for pipes operating between -30°C and 100°C.

Processing Technology: A powdered epoxy is electrostatically applied to a heated pipe, where it melts and cures to form a continuous, uniform film. We offer both single and two-layer FBE systems.

Benefits:

  • Strong Adhesion: Forms a robust bond with the steel, providing excellent resistance to cathodic disbondment.
  • High Mechanical Strength: Resists bending and impact, making it ideal for directional drilling and other demanding applications.
  • Environmental Stability: Offers reliable protection in a wide range of temperatures.

2PE/3PE and 3LPP Coating

These multi-layer coating systems are designed to provide excellent anti-corrosion and mechanical protection for buried steel pipes, with each system tailored for different operating temperatures.

Coating Structure and Technology

2PE (Two-Layer Polyethylene): This system consists of an inner adhesive layer and an outer polyethylene layer.

3PE (Three-Layer Polyethylene): This system adds a layer of Fusion Bonded Epoxy (FBE) directly onto the steel pipe for superior adhesion and corrosion resistance. This is followed by an adhesive and a polyethylene outer layer.

3LPP (Three-Layer Polypropylene): Similar in structure to 3PE, this system uses a polypropylene outer layer instead of polyethylene.
