1、 Product Features
The BZYP type straight pipe pressure balance compensator has two working bellows at each end and a balance bellows in the middle. The expansion joint is subjected to internal pressure thrust through a load-bearing component (large pull rod or tongue tube). Therefore, the piping system only requires a middle fixed bracket. This type of expansion joint can only absorb axial displacement.

2、 Installation and usage precautions
1. This type of expansion joint is generally used on overhead straight lines and installed horizontally.
2. After the installation of the expansion joint is completed, all small pull rods need to be removed.
3. To reduce the elastic reaction force of the expansion joint on the support, this type of expansion joint can be pre tensioned or pre compressed before installation (which can be achieved by adjusting the small tension rod on it).
