The ASME/ANSI B16.48 Figure 8 blind and spacer flange, also known as a spectacle blind, is a specialized pipeline accessory used to isolate, block, or open flow in piping systems. It consists of two parts connected by a small web: one solid end (the blind) for blocking the pipeline and one open end (the spacer) for allowing flow. The figure-8 design enables quick and convenient switching between open and closed states, making it ideal for maintenance and operational flexibility in industrial systems.
Materialspezifikationen:
Figure 8 flanges are available in various materials to suit different applications:
- Kohlenstoffstahl: ASTM A105, A516 Gr. 70
- Edelstahl: ASTM A182 F304, Nr. F316
- Stahllegierung: ASTM A182 F11, F22
- Duplex Edelstahl: ASTM A182 F51, Nr. F53
- Nickel-Legierungen: Inconel, Monel, Hastelloy
Material selection depends on system requirements such as pressure, Temperatur, and corrosion resistance.
