AYVAZ DBKK-90 Externally Pressurized Welding Neck Expansion Joint DN300
Safe thermal expansion management under high temperature and pressure.
The AYVAZ DBKK-90 Externally Pressurized Expansion Joint is built for reliable thermal growth management in demanding industrial lines. Moreover, its externally pressurized bellows design resists high pressure surges far better than conventional alternatives. Therefore, engineers specify it wherever pipework must absorb axial movement without compromising safety.
Welding neck ends provide a fully sealed, leak-tight connection, and in addition they reduce the need for frequent maintenance. The unit operates from -80°C to +427°C and carries a PN16 pressure rating at DN300. Furthermore, it conforms to EN 12952, EN 12953 and ASME, making it suitable for steam, hot water and process liquids.
