AYVAZ SISKKB-200 Seismic Expansion Joint Threaded DN32
Keeps piping intact when buildings move.
In high-rise structures, the AYVAZ SISKKB-200 Seismic Expansion Joint absorbs earthquake-induced structural movement and protects pipelines from damage. Moreover, its DN32 bore and 200 mm overall length allow integration even in tight spaces. In particular, the unit delivers flexibility in lateral, axial and angular directions, preventing pipe ruptures. Furthermore, the threaded connection requires no welding or flanges, therefore shortening installation time.
The stainless steel AISI 304 bellows maintains stable performance across an extreme temperature range of -80°C to +427°C. In addition, a design pressure of 12 bar suits demanding piping conditions. The St 37.2 carbon steel connection components increase durability. As a result, the assembly tolerates movement without losing sealing integrity or mechanical strength.
AYVAZ SISKKB-200 Seismic Expansion Joint — Technical Specifications
This expansion joint serves firefighting lines, HVAC and heating-cooling circuits, and domestic hot and cold water systems. Moreover, hospitals, schools and public buildings rely on it for seismic compliance. Consequently, industrial plants also specify it where structural integrity must be preserved. Its material construction lowers maintenance costs over a long service life.
