SA style molded rubber expansion joints are designed to absorb movements and stress on piping systems, compensate for pipe misalignment, reduce vibration and system noise. They also protect against start-up forces as well as system surges. All SA style joints come standard with ANSI 150# solid floating metallic flanges. The design of the SA 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 SA style design has a long radius arch allowing for self cleaning and thus eliminating the need for a filled arch. The sa style is the most economic choice when it comes to rubber expansion joints. The SA is available on request to meet the requirements of the U.S.C.G.
