Metal Bellow Seals: One of the Strongest Mechanical Seals

Metal bellows are the elastic vessels which can be compressed when in pressure. Metal bellows are usually used for high temperature since it contains of an elastic element. These are applied outside the vessel or it can also be extended under the vacuum. As long as you use the device, the elastic sinks and the Metal Bellow Seals comes back to the original size when the pressure or vacuum is released.

Characterized by flexible friction ring installed in all the relative displacement, the device can be compensated by the flexible bellows that allows installation of friction sealing ring which has a large deviation. These are high-technology product that can bear resemblance to the original leather bellows used traditionally in fireplaces and forges. They are ideal for various industrial applications. You have to choose the right one as per your requirement.

Since, seals are the essential requirement of different pumps and various other industrial applications. Thus, it needs to be ensured that no leakage from pumps and other devices and machines for oil, lubricants and gas is found. Metal Bellow Seals are ideal for the situation as per industrial requirements. Bellow seals are divided into different forms that include formed, welded and electroformed.

Types Of Metal Bellow Seals With Different Features And Specifications:

Metal Bellow Seals are ideal when the pressure is applied to the outside of the vessel or extended under vacuum. These are great for various industrial domains and machineries. These are into the category of mechanical seals that are used inside of a pump from the outside world to prevent leakage. One such seal is mounted on the pump shaft.

Welded Metal Bellows are ideal for oil, gas and chemical industries. These are popular as a core sealing technology as they are the new sealing technologies which include high-temperature non-contacting gas lubricated seals ad high temperature corrosion resistant seals.

Properties Of Metal Bellow Seals:

• In the manufacturing process of making the seal, a sheet of diaphragms made of high temperature heat-resistant alloy and brazed is used alternately along with their inner and outer edge portions.
• The entire series of diaphragms will assume a corrugation-like effect with a total thickness, substantially greater than the total thickness of the individual diaphragms

These bellows can eliminate elastomers in the chemical process industry due to temperature limits. The upper and lower temperature limit of bellow seals prevents from sealing many hot resins, polymers and cryogenic applications. In corrosive mediums like acid or alkali, you can choose for fluorine made bellow seals and eve these can reduce the compensation mechanism of frictional resistance.

Though these seals are the most demanding type of seals available in low and high temperature designs and patterns as these are the safest and the most hazard-free device to work with. With numerous added benefits associated with these seals, you can choose the right model and place of your order at the right manufacturer or an authorized supplier.
