Double Arc Bellows
SHAKTI RUBBERS DA style dual arch handcrafted rubber expansion joints are designed to absorb movements and stress on piping systems, compensate for pipe misalignment, reduce vibration, and system noise. Double arch protects against start-up forces as well as system surges. All DA style joints come standard with ANSI 150# split metallic flanges. The design of the DA style does contain metallic reinforcement in the carcass of the bellows or as per the pressure requirement of the customer. The carcass has a minimum of four layers of high tensile synthetic fabric. Each layer is impregnated with a rubber or synthetic compound. This allows movement and flexibility between the layers of fabric. The DA style design has a long radius arch allowing for self-cleaning and thus eliminating the need for a filled arch. The DA style is the most economic choice when it comes to dual arch rubber expansion joints.
