ANSI B16.5 Blind Flange
Product Detail
standard







Product introduction
Blind (BL) Flanges are a type of pipe flange used to seal the end of a piping system or vessel. They are designed to block off flow, making them ideal for applications where future expansion, maintenance, or inspection is required. Below are the key features and details about BL flanges:
1. Design:
- BL flanges are solid discs with no bore (hole) in the center.
- They have bolt holes around the perimeter to match the corresponding pipe flanges, allowing them to be bolted into place.
- The sealing surface is typically raised (RF), flat (FF), or ring-type joint (RTJ), depending on the application.
2. Applications:
- Used to close off the ends of pipes, valves, or pressure vessel openings.
- Commonly employed in piping systems that require periodic inspection, cleaning, or future expansion.
- Suitable for high-pressure and high-temperature environments.
3. Advantages:
- Provides a secure and leak-proof seal.
- Easy to install and remove, making them ideal for maintenance purposes.
- Can withstand high pressure and temperature conditions.
4. Limitations:
- Adds weight to the piping system due to their solid design.
- Not suitable for applications requiring continuous flow.
5. Standards:
- BL flanges are manufactured according to standards such as ASME B16.5, ANSI, DIN, and EN.
6. Installation:
- Installed by aligning the bolt holes with the mating flange and tightening the bolts to create a tight seal.
- Gaskets are used between the BL flange and the mating flange to ensure a leak-proof connection.
Blind flanges are essential components in piping systems, providing a reliable way to isolate sections of a pipeline or vessel. They are widely used in industries such as oil and gas, chemical processing, and water treatment. Let me know if you need more information!
