Supplier's note

  1. Technical Breakthroughs:

    • The Pro Model’s ±0.5% diameter tolerance enables seamless integration in precision machinery.
    • 500 MPa yield strength (43% higher than Base) ensures safety in high-pressure oil drilling.
    • API certification on Pro Model expands applicability to offshore drilling systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard gas or boiler pipe installations where cost-efficiency is prioritized.
    • Advanced Model: Suited for chemical plants needing enhanced corrosion resistance and tighter tolerances.
    • Pro Model: Best for extreme environments (e.g., deep-sea oil rigs) requiring API compliance and ultra-high strength.

With the Pro Model’s API-certified 500 MPa strength, you can safely deploy pipes in offshore drilling, where pressure exceeds 10,000 psi. Pair this with its ±0.5% tolerance to ensure flawless alignment in complex machinery.
