What is blind disk or flange cover?

A blind disk, also known as a blind flange or flange cover, is a type of flange that is used to close or seal the end of a pipe, valve, or vessel. It is essentially a solid disk with holes for bolts, but it does not have an opening or a connection for fluid or gas flow.

Blind disks are commonly used in piping systems when a temporary or permanent closure is needed. They can be installed at the end of a pipe to isolate a section of the system, block off a line for maintenance or repair, or prevent the flow of fluids or gases. Blind disks are often used in situations where a future connection or expansion may be required.

These flanges are available in various sizes, materials, and pressure ratings to suit different applications. They are typically made from materials such as carbon steel, stainless steel, or alloy steel, depending on the requirements of the system.

Blind disks are installed by bolting them to the flange face using the holes provided. They are tightened securely to create a leak-proof seal. When the blind disk is no longer needed, it can be easily removed and replaced with an appropriate flange connection.

How to produce blind disk or flange cover?

Blind disk production process: generally divided into four types: forging, casting and forging, middle plate cutting and casting. Among them, forging products have the highest price, followed by medium plates, and casting and forging are the lowest. And casting is the most inferior process. The quality is good for forging and medium plates, while forging and forging are slightly worse.

Overall, blind disks or flange covers are essential components in piping systems to provide closure and sealing when necessary, ensuring the integrity and functionality of the system.
