AYVAZ DBKF-60 Externally Pressurized Expansion Joint DN25
Protects the bellows from external pressure while absorbing axial expansion reliably.
The AYVAZ DBKF-60 Externally Pressurized Expansion Joint delivers safe expansion control and long service life in high-pressure lines. In addition, its externally pressurized design shields the bellows from external pressure and improves system stability. Moreover, the St 37.2 carbon steel outer jacket guarantees mechanical durability under demanding operating conditions.
The AISI 316 stainless steel bellows provides reliable operation in aggressive process environments, thanks to its corrosion resistance. Furthermore, the wide temperature range from -80°C to +427°C supports both cryogenic and high-temperature applications. The flanged DIN/EN connection and PN16 pressure class allow straightforward integration into existing pipelines.
