Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Sealing & Connection: Designed to create tight, leak-proof seals in pipe and vessel systems using ASTM A105 Grade B forged carbon steel, ensuring compliance with ANSI standards.
  • Maintenance Accessibility: Equipped with a hinged mechanism and hexagonal nuts arranged in a circular pattern, enabling easy opening for cleaning, inspection, or repair.

Key features

  • 1. Material Technology: Forged ASTM A105 Carbon Steel

    • With forged ASTM A105 carbon steel, ensure superior strength and corrosion resistance compared to standard carbon steel flanges*. This material is engineered to withstand harsh industrial environments, making it ideal for chemical processing, food handling, and high-pressure applications.

  • 2. Interactive Design: Hinged Mechanism for Easy Maintenance

    • With a hinged design, easily open and close the flange for maintenance without disassembling the entire system*, reducing downtime by up to 50% compared to traditional flanges requiring full disassembly*.

  • 3. Performance Parameters: ANSI-Compliant Raised Face (RF) Design

    • With an ANSI-standard raised face (RF) design, achieve secure sealing under high-pressure conditions, outperforming flat face flanges in critical applications*. The RF surface ensures precise alignment and leak-proof connections.

  • 4. Scenario Solutions: Customizable Material and Configuration

    • With customizable material options (e.g., stainless steel for food-grade applications), adapt to diverse industrial scenarios*, such as chemical processing, oil refining, or commercial piping systems. The threaded connection and forged construction ensure compatibility with varied operational demands.

  • 5. Certification Standards: Dual CE and ASTM A262 Compliance

    • With CE and ASTM A262 certifications, guarantee compliance with safety and corrosion resistance standards*, surpassing non-certified alternatives in reliability and regulatory adherence.
