Details
Double-arch products are used where more movement is needed. If the piping pressure is much higher, reinforced bolts should be assembled together with flanges. Reinforcement layer of the bellows by Nylon cords and at both ends by hardened steel wire rings. The floating steel flanges are drilled according to DIN, ANSI, BS, JIS and other standards.
