Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Pressure and Temperature Resistance: Designed to handle high-pressure (PN16/300LBS) and high-temperature environments, ensuring reliable performance in demanding industrial applications.
  • Multi-Type Connectivity: Combines blind flange, weld neck flange, and threaded flange functionalities to block fluid flow, provide secure pipe connections, and enable versatile installation methods.

Key features

  • 1. Material Technology: Corrosion-Resistant A105 Carbon Steel

    • With A105 carbon steel and ASTM A262 certification, ensure corrosion resistance and structural integrity in harsh environments like chemical processing or oil & gas systems. This material outperforms standard carbon steel by resisting intergranular corrosion, extending service life in aggressive media.

  • 2. Interactive Design: Threaded Connections for Quick Assembly

    • With threaded connections, achieve rapid and secure installation without specialized welding equipment, ideal for on-site repairs or retrofitting. This design reduces assembly time by ~30% compared to traditional weld neck flanges*.

  • 3. Performance Parameters: High-Pressure PN16 (300LBS) Rating

    • With PN16 (300LBS) certification, withstand pressures up to 4800 psi, outperforming lower-rated flanges in demanding industrial applications. Suitable for high-stress systems, such as pipelines in power plants or petrochemical facilities.

  • 4. Scenario Solutions: Versatile Blind Flange for System Isolation

    • Designed for critical applications like chemical processing, the blind flange enables safe system isolation during maintenance, reducing downtime by ~20% compared to manual blockage methods*. Its threaded/weld neck compatibility ensures adaptability across industrial and commercial setups.

  • 5. Certification Standards: Compliance with Global Regulations

    • Complies with CE and ASTM A262 standards, ensuring safety and corrosion resistance. This guarantees compatibility with EU regulations and international quality benchmarks, surpassing non-certified alternatives in reliability and safety.

Supplier's note

  1. Technical Breakthroughs:

    • ASTM A262 Compliance: Mitigates intergranular corrosion risk in corrosive environments.
    • Threaded Design: Reduces installation time by 30% compared to welded alternatives.
    • A105 Steel: Delivers 20% higher tensile strength than generic carbon steel grades.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial applications (e.g., water treatment) requiring PN16 ratings.
    • Advanced Model: Suited for oil & gas systems needing PN25 pressure and high-temperature resilience.
    • Pro Model: Designed for extreme scenarios like offshore drilling (API 6A compliance) or chemical processing.

With the Pro Model’s 600°C tolerance, you can handle high-temperature gases safely. Pair its stainless steel body with the threaded option to achieve a corrosion-resistant, quick-install solution.
