Ayvaz SISKKB-100 Seismic Expansion Joint Threaded DN250
Protects piping systems from earthquake-induced structural movement.
Ayvaz SISKKB-100 Seismic Expansion Joint absorbs earthquake and building movement in high-rise and industrial piping. In addition, its DN250 nominal diameter and only 100 mm overall length deliver high flexibility even in tight spaces. Moreover, it resists lateral, axial and angular movement fully. Furthermore, the threaded connection eliminates welding, which speeds up installation.
The stainless steel bellows (EN 1.4307) provides superior corrosion resistance. In addition, St 37.2 carbon steel connection parts guarantee mechanical strength. The design pressure is 12 Bar (PN12), and the unit performs stably from -80°C to +427°C. Consequently, it ensures safe operation even under demanding industrial conditions. It complies with EN 1391, ISO 10619 and ASME B31.
