AYVAZ DBKF-60 Externally Pressurized Expansion Joint DN125
Protects the bellows from system pressure for long, maintenance-light service.
The AYVAZ DBKF-60 Externally Pressurized Expansion Joint DN125 delivers safe expansion management in high-temperature and high-pressure lines. In addition, its externally pressurized design shields the bellows element from system pressure. Consequently, it reduces the load on the bellows and supports a long service life.
With a DN125 nominal diameter, this expansion joint absorbs movement effectively in medium and large bore pipelines. Moreover, the AISI 316 stainless steel body resists corrosion across a working temperature range of -80°C to +427°C. The PN16 pressure class and flanged connections to DIN and ANSI standards, in particular EN 1092, DIN 2633 and ASME, simplify installation. As a result, the unit performs reliably under high temperature differentials.
