HNMason Single Sphere Flexible Rubber Expansion Joint is 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. Single Sphere Flexible Rubber Expansion Joints come standard with ANSI 150# solid floating metallic flanges. the design of the Single Sphere Flexible Rubber Expansion Joints 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 Single Sphere Flexible Rubber Expansion Joint design has a long radius arch allowing for self cleaning and thus eliminating the need for a filled arch. the Single Sphere Flexible Rubber Expansion Joint is the most economic choice when it comes to rubber expansion joints.
