The ASME/ANSI B16.5 Blind (BL) flange is a solid flange with no center bore, designed to close or seal the end of a piping system, valve, or pressure vessel. It is commonly used in systems requiring isolation, inspection, or maintenance. Blind flanges can withstand high pressures and are versatile for use in various industries, including oil and gas, chemical processing, power generation, and water treatment.
Material Specifications:
Blind flanges are available in a variety of materials to meet diverse application requirements:
- Carbon Steel: ASTM A105, A350 LF2
- Stainless Steel: ASTM A182 F304, F316, F321
- Alloy Steel: ASTM A182 F11, F22
- Nickel Alloys: Inconel, Monel, Hastelloy
- Duplex Stainless Steel: ASTM A182 F51, F53
Material selection ensures excellent performance in high-pressure, high-temperature, or corrosive environments.
Key Features:
