AYVAZ DBKF-30 Externally Pressurized Expansion Joint DN125

Reliable axial expansion control that protects high-pressure piping and extends system service life.

The AYVAZ DBKF-30 Externally Pressurized Expansion Joint absorbs axial expansion in high-pressure lines to protect system integrity. In addition, its DN125 diameter and 30 mm stroke capacity suit a wide range of industrial installations. Furthermore, it is preferred in power generation plants and petrochemical factories.

An AISI 304 stainless steel bellows delivers exceptional resistance to aggressive media. Moreover, St 37.2 carbon steel flanges provide a robust connection to the pipeline. As a result, the externally pressurized design shields the bellows from external pressure and clearly extends product life. The unit handles 16 bar design pressure from -80°C to +427°C.
