ADVANTAGES

Spherical joints have a distinct advantage over metallic expansion joints for corrosive applications and installations requiring a high cycle life. The contour prevents sediment accumulation and creates less turbulence and pressure drop than spool joints. The seal bead eliminates any requirement for gaskets between mating flanges. Spheres may be installed on raised-face or flat-face flanges.

APPLICATION AREAS

Rubber expansion joint, as it's name, is mainly composed of rubber. It has various kinds of styles, and today I'm gonna to introduce one type, the "Double sphere" one.

First of all, about the structure.
Double ball rubber expansion joint is composed of two flanges and one double ball rubber expansion joint. It is a joint composed of an inner rubber layer, a reinforcing layer with multiple layers of squeegee nylon cord fabric, and a rubber tube compounded by an outer rubber layer. The pictures are as follow.

Secondly, about the material.
The rubber part is usually be EPDM, but NBR, NR, SBR and Neoprene are also common rubber materials. About the flange material, it commonly be CS, SS, CS zinc plated, galvanized, epoxy coated, CS epoxy resin coating and so on.

Third,about function and application.
The rubber expansion joint is an "expert" on shock absorbtion. It has large displacement compensation ability, can compensate for axial, lateral and angular displacement, reduce noise, reduce vibration and certain anti-corrosion ability.
Rubber-like expansion joints have a large displacement compensation ability, can compensate for axial, lateral and angular displacements, reduce noise, reduce vibration and certain anti-corrosion capabilities. It has the characteristics of high pressure resistance, good elasticity, large displacement, good vibration absorption and noise reduction, and easy installation. It can be widely used in water supply and drainage, HVAC, fire protection, compressors, papermaking, pharmaceuticals, ships, pumps, fans and other pipelines. system.
