ASME B16.48 ASTM A182 F51 Duplex Steel Spectacle Blind Flange Figure-8 Blanks


Figure-8 flanges, also known as sight or spectacle flanges, are specialized components used in piping systems to facilitate maintenance, isolation, and inspection of pipelines. The figure-8 design features two circular ends connected by a narrow waist, which offers flexibility in alignment and connection. The material can be made from various materials including carbon steel, stainless steel, and duplex stainless steel, depending on the application requirements. Their unique design allows for efficient operation and flexibility in various industrial applications.

Advantages:

  • Flexibility: The figure-8 design allows for slight misalignments, making installation easier and reducing stress on the pipe system.
  • Strength: Offers a good balance of strength and weight, making them suitable for high-pressure applications.
  • Corrosion Resistance: Depending on the material, they can offer excellent resistance to various corrosive environments.
