The ASME/ANSI B16.47 Series A and B Blind (BL) flanges are solid, circular flanges designed to close or seal the ends of large-diameter piping systems. These flanges are critical for systems that require isolation for maintenance, testing, or inspection. Series A flanges are larger, thicker, and stronger, ideal for high-pressure applications, while Series B flanges are more compact and suitable for less demanding environments.
Material Specifications:
Blind flanges in Series A and B are available in a variety of materials to meet diverse operational 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
The material selection ensures excellent performance under extreme conditions, such as high pressure, high temperature, or corrosive environments.
Caractéristiques principales:
- Solid Construction: Provides a secure seal, preventing leaks and ensuring system isolation.
- High Strength: Designed to withstand extreme pressure and temperature conditions.
- Versatility: Series A for critical, high-stress applications and Series B for standard use.
- Wide Range of Sizes: Accommodates large-diameter pipes up to 60 inches.
- Standards Compliance: Manufactured per ASME/ANSI B16.47 specifications for reliable performance and dimensional accuracy.
Applications:
- Oil & Gas: Used for isolating pipelines and pressure vessels during maintenance.
- Chemical Processing: Sealing systems handling hazardous or corrosive fluids.
- Power Generation: High-pressure systems in thermal, nuclear, and hydropower plants.
- Marine and Offshore: Piping systems in ships and offshore platforms.
- Water Treatment: Desalination, wastewater, and large-scale distribution systems.
