S20 Double Sphere Rubber Expansion Joint Di Flange

Style molded S20 double sphere rubber expansion joints are designed to absorb movements and stress on piping systems, compensate for pipe misalignment, reduce vibration and system noise. The style S20 protects against start-up forces as well as system surges. All S20 style joints come standard with solid floating metallic flanges and metallic root rings Flange standard can be ANSI 150, JIS10K/16K, DIN PN10/16 etc. The design of the S20 style does not contain any metallic reinforcement in the carcass of the bellows. Instead 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 S20 style design has a long radius arch allowing for self cleaning and thus eliminating the need for a filled arch. The S20 style is the most economic choice when it comes to dual arch rubber expansion joints.
