Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Pressure Connection: Designed for threaded and flanged connections, enabling secure sealing in systems rated up to PN16 (16 bar), suitable for demanding industrial and commercial applications.
  • Versatile Pipe Integration: Supports multiple piping configurations through types like weld neck (WN), socket weld, and blind flanges, ensuring compatibility with diverse infrastructure needs.

Key features

  • 1. Advanced Material Technology

  • With forged stainless steel construction, achieve superior corrosion resistance and durability in harsh industrial environments. Stainless steel outperforms carbon steel in resisting rust and chemical exposure*, ensuring long-term reliability.

  • 2. Effortless Interactive Design

  • With a threaded connection interface, simplify installation and maintenance compared to welded alternatives. The pre-threaded design allows quick assembly without specialized tools*, reducing downtime.

  • 3. High-Performance Pressure Handling

  • With a PN16 rating, safely manage pressures up to 16 bar—ideal for demanding applications like oil and gas pipelines. Outperforms lower-rated flanges in high-pressure scenarios*, ensuring robust performance.

  • 4. Versatile Scenario Solutions

  • Designed for airtight sealing in industrial, plumbing, and manufacturing systems, these flanges adapt to both low- and high-pressure environments. Their weld neck and socket weld variants provide tailored solutions for diverse piping configurations*, enhancing system integrity.

  • 5. Certified Quality Assurance

  • With ISO-compliant manufacturing, meet global safety and performance standards. This certification ensures compatibility with international engineering protocols*, reducing compliance risks for industrial projects.

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model’s Alloy Steel: With a PN40 rating, it outperforms industry benchmarks for high-pressure oil & gas applications.
    • Forged Construction: Eliminates weld seams, reducing failure risks in vibration-heavy environments.
    • ISO Compliance: Ensures seamless integration with global infrastructure standards.
  2. Version Selection Guide:

    • Base Model: Ideal for general plumbing and low-pressure systems (e.g., residential HVAC).
    • Advanced Model: Suited for corrosive environments (e.g., chemical plants) with its F316 stainless steel.
    • Pro Model: Choose for extreme conditions—its F51 alloy handles temperatures up to 650°C and pressures 3x higher than competitors.

With the Pro Model’s alloy steel, you can safely manage high-pressure oil refinery operations. The Advanced Model’s chemical resistance ensures longevity in pharmaceutical systems. For cost-effective solutions, the Base Model provides reliable performance in standard applications.
