What Is Butt Welded Ring Loose Sleeve Flange?

Butt welded ring loose sleeve flange (PJ/SE) is a flange whose structure is similar to that of flat welded flange, but there are some differences.

The loose sleeve flange of the butt welding ring is a movable flange, which is generally matched on the water supply and drainage accessories. When the manufacturer leaves the factory, each end of the expansion joint has a flange, which is directly connected with the pipe and equipment in the project with bolts.

Specifically, the advantages of butt welded ring loose sleeve flange include:

• Cost saving: Because of its simple structure, it is relatively easy to manufacture and can save manufacturing costs.

• Easy to repair: Its unique construction makes it easier to repair and replace.

• Strong applicability: The welding ring loose sleeve flange has a wide range of application and can be used in a variety of different pipeline systems.

• However, compared with the flat welded flange, the stiffness of the butt welded loose sleeve flange is poor.

In addition, there are certain restrictions on the diameter of the pipe. Therefore, in practical applications, it is necessary to choose the appropriate type of flange according to the specific situation.
