Ayvaz SİSKKB-100 Seismic Expansion Joint Threaded DN100
Protects piping networks from earthquake and building settlement damage.
The Ayvaz SİSKKB-100 Seismic Expansion Joint protects piping against structural movement, therefore it is engineered for earthquake and building settlement conditions. In addition, its DN100 nominal diameter and 100 mm overall length allow installation even in tight spaces. The stainless steel bellows resists axial, lateral and angular movement simultaneously. Moreover, the threaded connection removes the need for welding or flange assembly, consequently shortening installation time considerably. It also delivers reliable operation at 12 Bar design pressure.
The stainless steel bellows structure absorbs axial, lateral and angular movement at the same time, which keeps connected pipelines stable during seismic events. A broad working temperature range from -80°C to +427°C supports continuous duty in demanding lines. Furthermore, St 37.2 carbon steel connection elements provide long-lasting performance. The threaded connection type requires no welding and no flange, which simplifies assembly.
Ayvaz SİSKKB-100 Seismic Expansion Joint — Technical Specifications
Hospitals, schools, shopping centres and public buildings commonly specify this joint for fire piping, potable water and HVAC systems, where it meets seismic safety standards. In addition, it plays a critical role in earthquake-resistant piping networks of high-rise residential and commercial buildings. Industrial cooling towers and hot water discharge lines also use it safely. Moreover, sprinkler systems and complex process water applications benefit from its performance.
Key Advantages
- Prevents pipe breakage and joint leakage during earthquakes
- Threaded connection avoids welding, reducing installation time and cost
