Loose Flange
A loose flange is a joint that connects two sections of piping or tubing, usually created by bolting two flanges together. The "loose" designation indicates that these flanges can be easily removed and replaced - ideal for maintenance, repairs, or even in certain assembly processes. Additionally, loose flanges help reduce vibrations from high-pressure flows and prevent the buildup of debris between pipe sections.

A loose flange is a two-piece component. The first piece is known as a stub end and the second piece is referred to as a backing flange. The stub end, which is a sleeve is shaped similarly to a short piece of pipe. This flange has a narrow shoulder on one end, with the other end of the hub that has been butt welded. 

The dimensions of the narrow shoulder are like the raised face of the flange, whereas the butt weld end of the stub-end is similar to the neck of a weld neck flange, down to the diameter and thickness. The back face of the hub of the loose flange is produced 0with a rounded transition that attaches the hub to the sleeve. 

1. Loose flanges have the freedom to swivel around the pipe. This facilitates the lining up of opposing flange bolt holes.


2. Lack of contact with the fluid inside the pipe leads to the greater durability of these flanges.
 

3. In piping systems that corrode or erode quickly, the loose flanges may be salvaged for re-use.


4. The pressure-holding capacity of lap joint flanges is small. But it is better than that of slip-on flanges.
 

5. The loose flange works as a backing ring on the stub.


6. The main advantage of a loose flange is that the bolt holes can be aligned with the matching flange after the welds have been completed.

7. They allow rotational alignment capability.


8. Because of the structure of a loose flange, it can swivel around the stub end and pipelining. When the piping system is assembled and disassembled frequently, it is better to use a Lap joint flange. It means the flange can work even if the two flange bolt holes are misalignment.

9. In a corrosive situation, the flange joints need to be exchanged very soon. For a loose flange, only the stub end is in touch with the pipe and fluid, the backing flange does not need to touch it.
