Supplier's note

  1. Three Breakthroughs:

    • CE Certification: Enables seamless deployment in EU projects, ensuring compliance with safety standards.
    • Hybrid Manufacturing: Combining hot rolling and cold drawing enhances both strength and surface precision.
    • Precision Tolerance: ±1% tolerance ensures flawless integration with high-precision machinery components.

  2. Version Selection Guide:

    • Base Model: Ideal for standard construction projects (e.g., residential plumbing) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for medium-pressure systems (e.g., industrial pipelines) requiring enhanced corrosion resistance.
    • Pro Model: Tailored for extreme environments (e.g., offshore oil rigs) with heavy loads and corrosive chemicals. Its zinc-plated coating and reinforced walls ensure longevity even in harsh conditions.

*Pro Model’s pressure rating exceeds industry benchmarks by 30%, enabling safe use in high-stress applications like deep-sea drilling.
