The double bellow joint features an additional layer of convolutions, creating two bellows connected by an intermediate pipe section. This design provides even greater flexibility and movement capability compared to the single bellow joint.

One major advantage of the double bellow joint is its ability to absorb larger amounts of axial compression or extension movements. It can also accommodate higher levels of lateral deflection and angular rotation. These characteristics make it suitable for applications where significant movement or vibration isolation is required.

The double bellow joint’s increased flexibility allows for enhanced stress distribution across its multiple convolutions. This helps to minimize the risk of localized stress concentrations, which can lead to premature failure or fatigue. 結果として, the double bellow joint offers improved longevity and reliability in demanding operating conditions.

Similar to the single bellow joint, the double bellow joint is highly resistant to corrosion and chemicals. It is often constructed with high-quality elastomers that can withstand aggressive media and harsh environments. This ensures optimal performance and extends the service life of the expansion joint.
