Blind Flanges Is To Seal Off The End Of A Pipe , Providing A Removable Seal

Blind flanges is to seal off the end of a pipe, providing a removable seal

Blind flange , officially known as a flange cover, is also called a blind flange or pipe plug. It is a type of flange without a hole in the middle. Its main purpose is to seal off the end of a pipe, providing a removable seal.

Contrary to all the flange types seen above, blind flanges do not have a center hole, and are used to blind or seal a pipeline, a valve/pressure vessel and block the flow of the fluid.Blind flanges have to withstand remarkable mechanical stress due to the system pressure and the required bolting forces.
Blind flanges allow easy access to the pipeline, as they can be easily unbolted to let the operator execute activities inside the terminal end of the pipe (this is also the reason why the blind flange type is used as manhole for pressure vessels, at times).
It is maybe interesting to observe that, while this flanges type is easier to manufacture, they are sold at a premium average cost per kilogram compared to the other flange types.

Why Choose Our Blind Flanges?

• Reliable Sealing: Effectively seals pipelines, valves, or pressure vessels to block fluid flow, ensuring no leaks and maintaining system integrity.
• High Mechanical Strength: Designed to withstand significant mechanical stress, including system pressure and bolting forces, making it suitable for demanding applications.
• Easy Access: Can be unbolted for straightforward access to the pipeline or pressure vessel, facilitating maintenance, inspection, or use as a manhole.
• Versatile Use: for applications where a permanent or temporary seal is needed, such as in pipelines, pressure vessels, and as manholes.
• Quality and Compliance: Made to meet rigorous standards (GB/T9119-2010, HG/T20592-2009, DIN, ASME, BS, JIS) and available in various high-quality materials like 304, 316L, and high-strength alloys.
