Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Industrial Fluid Transport: Designed for applications such as oil, gas, chemical fertilizer, and hydraulic systems, ensuring safe and efficient conveyance of fluids under high-pressure conditions.
  • Structural Support: Built with ERW (Electric Resistance Welded) technology and DX51D galvanized steel, providing robust durability for construction, boiler piping, and drilling operations.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With galvanized DX51D steel, ensure long-lasting durability in harsh environments like chemical plants or marine settings. Outperforms non-galvanized pipes by resisting rust and corrosion for up to 5 years*.

  • 2. Compliance with Global Standards

    • With RoHS certification and API compliance, meet strict environmental and industrial safety requirements. Suitable for regulated sectors like oil drilling and construction, unlike non-certified alternatives*.

  • 3. High-Strength Performance

    • With Q195-Q345 steel grades and ERW (Electric Resistance Welded) construction, handle extreme pressures and stresses. Delivers 20% higher load capacity than standard welded pipes* for hydraulic and boiler systems.

  • 4. Versatile Scenario Solutions

    • With applications in oil, boiler, and chemical pipes, adapt to demanding industrial needs. Designed for continuous operation in extreme conditions like offshore drilling or high-temperature boiler systems*.

  • 5. Customizable Interactive Design

    • With processing services (cutting, bending, welding), tailor lengths (up to 12m) and shapes to fit complex projects. Achieve precise fits for custom installations compared to rigid, non-modifiable pipes*.

Supplier's note

  1. Technical Breakthroughs:

    • Galvanized Coating: Triple-layer zinc coating outperforms industry benchmarks, extending lifespan in corrosive chemical environments.
    • ERW Welding: Seamless joints reduce leakage risks by 25% compared to traditional welding methods.
    • API Compliance: Pro Model meets API 5L specifications, enabling safe use in high-pressure oil drilling.

  2. Version Selection Guide:

    • Base Model: Ideal for standard fluid pipelines or low-pressure applications (e.g., residential plumbing).
    • Advanced Model: Choose for medium-pressure systems (e.g., boiler pipes) needing enhanced corrosion resistance.
    • Pro Model: Required for heavy-duty scenarios like offshore drilling or chemical processing, where extreme pressure and corrosive fluids are present.

With the Pro Model’s 3000 PSI rating and API certification, you can safely handle high-pressure oil transport. Pair its galvanized finish with ERW precision to minimize maintenance in marine or industrial settings. For construction projects needing quick assembly, the Base Model’s standard cuts reduce on-site processing time by 20%.
