AYVAZ DBKF-90 Externally Pressurized Expansion Joint DN65
Protects high-pressure piping by absorbing axial thermal expansion reliably.
The AYVAZ DBKF-90 Externally Pressurized Expansion Joint delivers safe expansion control and long service life on high-pressure lines. Consequently, it operates within a PN16 pressure class and a temperature range of -80°C to +427°C. In addition, the AISI 316 stainless steel bellows resists corrosion and high temperatures.
This expansion joint features an externally pressurized design that shields the bellows from overpressure. Moreover, the AISI 316 stainless steel bellows maintains dependable performance across a wide temperature span. Its flanged connection to PN16 DIN/EN simplifies installation and maintenance. It conforms to EN 12640 and ASME B16.34 standards.
