A blind flange is a type of flange used to block the flow of fluid in a piping system. It is essentially a plate with a raised rim around its perimeter, which is bolted to a pipe or fitting to create a seal.
Where To Use Blind Flanges
Piping systems where a quick shutdown or isolation is required.
Applications where a blockage is needed to prevent backflow or pressure surges.
Systems that require a high level of safety and security, such as in the chemical or petrochemical industry.
Key Features Of Blind Flanges
Simple and compact design.
High sealing efficiency due to the raised rim and bolted connection.
Can be used in a variety of applications, including high-pressure and high-temperature systems.
How To Use Blind Flanges
Identify the application requirements and ensure the blind flange meets the necessary specifications.
Inspect the blind flange for any damage or defects before installation.
Bolt the blind flange to the pipe or fitting using high-strength bolts and follow the manufacturer's instructions.
How Blind Flanges Is Manufactured
The manufacturing process for blind flanges typically involves cutting, machining, and finishing processes to ensure precise dimensions and surface quality.
Technical Specification Of Blind Flanges
