Ayvaz’s special stainless steel expansion joints with carbon steel weld ends are designed to be used for compensating movements and misalignments in exhaust systems in situations with relatively high axial or small lateral movements and combination of these at the same time. Due to the double ply bellows, exhaust expansion joints are more flexible an their life cycle is greater than the simple expansion joints. According to the maximum operating temperature, weld end material could also be made by stainless steel or nickel alloys.
