28-Convolution Flex Metal Bellows

28-Convolution Flex Metal Bellows

28-Convolution Flex Metal Bellows (28-wave flexible metal bellows) offers the following core advantages: ultra-high flexibility, long service life, strong displacement compensation, low stress, stable pressure resistance, and excellent vibration damping. It is specifically designed for long-stroke applications, high-frequency cycling, high-temperature and high-pressure environments, and precision systems.

 

 

 

I. Structural and Flexibility Advantages (28-wave core)

Exceptional Flexibility: 28 convolutions provide a longer effective deformation length, offering 30–50% greater flexibility than products with fewer convolutions.

Lower bending/expansion resistance reduces additional stress on pipes and equipment

Easily absorbs axial, lateral, angular, and combined displacements

Long Service Life and High Fatigue Cycle Life More convolutions → smaller deformation per convolution → lower stress → significantly extended fatigue life.

Suitable for continuous vibration and high-frequency thermal expansion/contraction conditions

Standard designs can withstand millions to tens of millions of cycles

II. Performance Advantages

Strong displacement compensation capability

Effectively absorbs: thermal expansion and contraction, equipment vibration, foundation settlement, and installation deviations

Greater compensation capacity (higher than fewer-wave designs for the same length)

Pressure resistance + reliable sealing

Fully welded / seamless structure, zero leakage, vacuum-resistant, high-pressure-resistant

Thin-walled precision forming + multi-layer / high-quality stainless steel / alloys (304/316/Inconel, etc.)

Vibration-Damping and Isolation Wave-Shaped Structure: Efficiently dampens vibrations, reducing equipment and pipeline noise as well as fatigue failure.

Temperature and Corrosion Resistance: Suitable for -200°C to 600°C+, steam, hot oil, acids, alkalis, and corrosive media.
