AYVAZ DBKK-90 Externally Pressurized Expansion Joint DN250
Extends bellows life while managing expansion safely in high-pressure lines.
Industrial piping systems rely on the AYVAZ DBKK-90 Externally Pressurized Expansion Joint DN250 for safe expansion control under high pressure. In addition, the externally pressurized design redirects internal pressure to the outer casing, therefore extending bellows service life. Moreover, production to EN 1477 and ASME B16.5 standards ensures reliable performance.
The unit operates at PN16 with a working temperature range of -80°C to +427°C, and the stainless steel structure delivers high resistance to seawater, acids and salt solutions. Its expansion capacity is medium to high, depending on system design. Furthermore, the externally pressurized technology protects the bellows in aggressive media and large temperature differences, consequently reducing maintenance needs.
