Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support & Industrial Infrastructure: Designed for heavy-duty applications such as construction frameworks, scaffolding, and industrial equipment support due to its high strength and corrosion resistance.
  • Fluid Transportation & Pressure Handling: Engineered to safely transport fluids, gases, and chemicals (e.g., oil, gas, hydraulic systems) in boiler, drilling, and chemical fertilizer applications.

Key features

  • 1. Corrosion-Resistant Galvanized Steel Coating

    • With a corrosion-resistant galvanized steel coating, you can ensure durability in harsh environments like marine or industrial settings compared to uncoated pipes*. The zinc layer prevents rust and extends lifespan in moisture-rich or chemical-exposed conditions.

  • 2. CE & ASTM Compliance for Global Standards

    • With CE and ASTM certifications, you can meet stringent international safety and quality standards, ensuring compliance in EU and global markets*. This dual certification streamlines regulatory approvals for cross-border projects.

  • 3. ERW Welding & Precision Tolerance for Structural Integrity

    • Using ERW (Electric Resistance Welded) technology, you can achieve seamless, high-strength joints that withstand high-pressure applications better than butt-welded alternatives*. Combined with a tight 1% tolerance, this ensures precise integration into complex systems.

  • 4. Customizable Processing Services for Project-Specific Needs

    • With on-demand processing services (welding/cutting), you can customize lengths and joints to fit specific project requirements efficiently*. This eliminates the need for post-purchase modifications, saving time and costs.

  • 5. Versatile Application Across Industries

    • Designed for boiler, oil, and structural applications, you can adapt this pipe to diverse projects without needing multiple specialized products*. Its compatibility with fluid, gas, and hydraulic systems makes it ideal for construction, energy, and manufacturing sectors.

Supplier's note

  1. Technical Breakthroughs:

    • Enhanced Corrosion Resistance: The Pro Model’s galvanized coating exceeds ASTM A123 standards by 30%, enabling use in offshore drilling platforms.
    • Precision Tolerance: ±1% wall thickness ensures seamless integration with high-pressure hydraulic systems.
    • Strength-to-Weight Ratio: Advanced Model’s 470 MPa tensile strength reduces material costs in bridge construction.

  2. Version Selection Guide:

    • Base Model: Ideal for standard applications (e.g., residential plumbing) where cost-efficiency is prioritized.
    • Advanced Model: Recommended for moderate industrial use (e.g., oil refineries) needing improved durability.
    • Pro Model: Best for extreme environments (e.g., marine or chemical plants) requiring triple the industry-standard corrosion protection. With its ERW welding precision, it guarantees zero leakage in high-pressure gas pipelines.
