What Are Flexible Pipe Joints?
Flexible Pipe Joints are a type of pipe fittings, and as the name flexible indicates, they are portable. Therefore, they are used to connect pipes that are prone to expansion and contraction due to thermal expansion and equipment that are prone to vibration, as well as to absorb vibration during their own operation.
Stainless steel such as SAE 304 is used as the basic material, but rubber is also used in some cases.
Also, general piping fittings such as screwed and flanged joints are available, and the length can be freely selected to some extent, so you can choose the one you like according to your piping design.
Applications of Flexible Pipe Joints
Flexible Pipe Joints utilize the flexibility of flexible pipe joints.
For example, if piping is directly connected to equipment that is a source of vibration, even if a foundation or anti-vibration frame is used, the vibration will be transmitted through the piping, causing the building itself to shake. Flexible pipe joints are used to insulate that vibration.
Flexible Pipe Joints are also used to absorb the stress caused by thermal expansion and contraction of steam pipes.
In addition, when existing piping is in the way when new piping work is required, it can be easily rerouted by using Flexible Pipe Joints.
Principle of Flexible Pipe Joints
Flexible Pipe Joints are basically made of stainless steel such as SAE 304.
Some fittings are made of rubber or other products, but general SAE is not flexible. Therefore, Flexible Pipe Joints made of SAE 304, etc. are basically made with a bellows or tubular structure to provide flexibility.
The tube structure is made flexible by forming a thin SAE plate into a corrugated shape like a spring. The blade structure is made flexible by sewing thin SAE plates together like a cloth.
By manufacturing in this way, it is possible to make Flexible Pipe Joints made of metal.
However, since it does not have the flexibility of rubber, a minimum bending radius called "minimum R" must be observed when using it. Flexible Pipe Joints may be damaged if bent beyond the minimum bending radius.
In addition, it is not enough to install a flexible pipe fitting for any purpose, but it is necessary to calculate the length of the flexible pipe fitting according to the application.
If the length is not long enough, not only will the effective seismic resistance and absorption of thermal expansion not be achieved, but the Flexible Pipe Joints will be damaged.
