Metal Flex Welded Bellows – Reliable Sealing Solutions for Harsh Industrial Environments

The engineering of metal flex welded bellows maximizes long-term durability and high-performance capability through the use of a precision engineered design that is able to accommodate very high levels of pressure and temperature from the application. Each of the Welded Bellows products has a long life cycle, as well as the added benefit of a uniform distribution of stresses; therefore, every product will experience an equal degree of wear and will not require the use of dynamic seals.

Advantages of Metal Flex Welded Bellows

Centrifugal Forces

When edge welded vacuum bellows form part of the rotating assembly, the centrifugal force generated by the rotating assembly creates a natural self-cleaning action which enhances stability.

Media Crystallization

The design of edge welded vacuum bellows does not allow for the possibility of media escaping as a result of either crystal formation or dramatic temperature fluctuation. This means that the edge welded vacuum bellows are extremely reliable when sealing difficult-to-seal types of media.

Ease of Maintenance

In-depth inspection (looking for excessive heat, leakage, fatigue) enables continuous reliable operation of edge welded vacuum bellows, as well as significantly reducing the number of replacement seals that would otherwise be required due to fatigue failure or cosmetic issues.

Applications 🛠 Metal Flex Welded Bellows

High-temperature seal usage:

The metal flex welded bellows can be used in conjunction with high-temperature pumps, molten salt systems, and multiple reactor types, as they are tolerant of long-term continuous usage at 450 degrees Celsius with a robust degree of reliability.

Corrosive media:

The metal flex welded bellows can provide extended service life in all types of chemically aggressive environments, including acidic, alkaline, and salt containing environments – in the Chemical, Pharmaceutical, and Electrode position industries.

High-speed dispersion pumping equipment:

The from the dynamic balance and rotor construction of the welded metallic bellows is well suited to support centrifugal pumps and compressors with speeds greater than 5000 rpm, providing stable effective sealing with reduced mechanical stress.

Prevention of crystallization and solidification:

The metal flex welded bellows are ideal for applications involving materials that tend to crystallize and become solid, e.g., concentrated salt brines or alkaline solutions, to allow for continued operation without the risk of premature mechanical seal failure.

FAQ

Is it possible for welded metallic bellows to function effectively in high-temperature conditions?

It is absolutely true that edge-welded metallic bellows are designed for continuous use at temperatures up to and including 450 degrees Celsius.
Definitely. Metric sizes greater than 150mm will have customization options available.
The initial stage involves confirming that the shaft is not excessively out-of-round. Then, the seal should be fitted firmly into its place using correctly calibrated tooling. After this, all of the fixings need to be evenly secured, and finally the shaft should be manually rotated to ensure that there are no points of interference between the mechanical seal and the shaft.
