Blind flange


Blind flange, also known as blind flange, is actually called blind flange. It is a type of flange connection. Actually, it's a flange without a hole in the middle.

Flange blind plates should not be galvanized when used in oil media systems, but should be hot-dip galvanized when used in other media systems. The minimum weight of the zinc coating should be 610g/m2, and the quality inspection of hot-dip galvanizing should be carried out according to CB */Z343.

Product Details

One of its functions is to seal the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. In terms of sealing effect, it has the same effect as the head and pipe cap. However, the head cannot be disassembled, and the flange blind plate is fixed with bolts, making it easy to disassemble. The blind flange materials include carbon steel, alloy steel, stainless steel, plastic, and so on. 

The blind flange serves as an isolation and cutting device, just like the head and pipe cap. Due to its good sealing performance, it is generally used as a reliable means of isolation for systems that require complete isolation. A blind plate is a solid circle with a handle, used for systems that are usually in an isolated state. 


The flange cover can be installed on the external thread of the pipe end, which can seal the pipeline and serve as a plug. It has dustproof, waterproof, and anti-corrosion effects. 

The flange cover mainly serves as a sealing function, without the need for any additional components during sealing. There are many holes around the flange cover, which are used to connect with the flange. Of course, there are also the most commonly used flange covers that are directly welded to pipes. The periphery of the flange cover is made of the hole diameter, which is convenient for assembly and can also be used for secondary use. It is also relatively convenient for maintenance.
