5 Applications of Metal Bellow Seals

Posted by Leak Proof Seals on July 10th, 2019

Metal bellow seals are some of the most common API seals which are used in many ways. There are several pros and cons of using them which are determined by their usage or application. Since these types of seals are so common, beginners or amateurs might want to learn about why or where these types of seals are being used.

Application of Metal Bellow Seals

Metal bellow seals are not just used in the oil industry. They are used for multiple reasons which might help you expand your own knowledge about them. Here are the top five applications of metal bellow seals:

Valve Sealing

The first and foremost application of metal bellow seals is in the valve sealing. They are ideal as seals to be used between housing and the rising system. This is due to the fact that they offer premium service of hiding the inner side from the outer components and protects it. In fact, European countries have made metal bellow seals to be a compulsory unit of valve sealing.

Vacuum Interrupter

Most of the transformers feature high-voltage of energy. In order to prevent mishaps and risks, the oxygen from around the transformers is to be removed which prevents the sparks from gaining momentum. This is where the metal bellow seals come into play as they are used to cover any places which might cause a spark of energy. Moreover, the inner section is evacuated completely to be filled with inert gas.

Mechanical Seals

Another popular application of the metal bellows is in the mechanical industry. They are used on pump shafts for preventing the leakage. The sealing should be done by a product which has a rotating ring and a stationary ring to provide optimal leak stoppage. Metal bellow seals are mounted on the pump shafts along with the bellow springs. This helps the two rings to face the pressure without being stressed.

Load Cells

It is impossible to talk about the application of metal bellow seals without mentioning load cells. Usually, load cell undergoes damage when too much pressure is put on the cells. In order to detect the strain, the gauge which is used for the low voltage current passage is used. Whenever there is a fluctuation, you can tell that there is disruption on the load cells.

It also shows up on the control panel for easier detection of the mechanics. In order to prevent that fluctuation, gauge is mounted with metal bellow seals which protect it from the negative impact.

Exhaust Bellows

In several industries including railway stations, metal bellow seals are used for controlling the self-vibration of the engines. This type of movement causes thermal expansion and rising of the temperature so the bellows are used for tying up with the funnel attached to gas pipes.

With this many application of metal bellow seals, you can easily come across API seals for your usage. Furthermore, metal bellow seals are some of the most reliable, long lasing and high-performance seals making them every end-user’s favorite choice.
