single sphere rubber joint

Yu-xiang® rubber expansion joints are flexible connectors made from natural or synthetic elastomers in which special fabrics are embedded  to provide physical reinforcement. rubber expansion joints provide a proven and flexible solution to accommodate many types of movements and requirements of industrial plant and equipment.

These include:
Accommodating for pressure loads.
Neutral axial, lateral and angular stress.
Reducing noise.
Isolating sources of vibration.
Compensating for misalignment at plant start up.
Prolonging the life of motive equipment.
They are used in all systems transporting fluids, slurries or gases under pressure, at ambient pressure or under vacuum over a wide range of temperatures.

Application areas are:
Air conditioning, heating and ventilating systems in industrial buildings, hospitals, hotels and on board ships.
Central and ancillary power generating stations in industrial buildings, factories, ships and off-shore.
Sewage disposal and water treatment plant, pumps, etc.
Process piping in pulp and paper manufacture.

Flanged DIN/PN, ANSI/ASA, British BS10, SAE 3000, JIS.
EPDM, Nitrile/NBR/Buna-N/Perbunan, Hypalon/CSM, Chloro-Butyl/IIR, Natural Rubber, Neoprene/Chloroprene, SBR/Buna-S, Gum Rubber,HNBR, ECO/Epichlorohydrin.
PTFE Lined or Viton Expansion Joints for Chemicals & Solvents.
Hump Hoses & Flexible Pump Connectors,Steel Mesh or Aramid Reinforced.

Yu-xiang®Spherical Molded Expansion Joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces. The molded single sphere and twin sphere designed bellows are inherently stronger than the conventional hand-built style spool arch type. Internal pressure within a “sphere” is exerted in all directions, distributing forces evenly over a larger area. The spherical design “flowing arch” reduces turbulence and sediment buildup.
