Rubber Flexible Expansion Joints Absorb Movements and Reduce Noise

Rubber flexible joints, also called rubber elastomer joints, is constructed of neoprene and nylon with internal and stainless steel rings external structures.

It can provide superior performance in absorbing movement and reducing mechanical noise, reliability and long service life. All result in improved plant safety and increased mechanical integrity of equipment.

The rubber flexible expansion joints are inserted in a rigid piping system for following functions:

• Absorb and relieve movement stresses.
• Reduce mechanical noise.
• Improve thermal stability.
• Generate horizontal, axial and angular displacement. And isolate vibration.
• Compensate for misalignment.
• Relieve system strain due to thermal change, load stress, pumping surges, wear of settling.
• Eliminate electrolysis between dissimilar metals.

Structures of rubber flexible joint

Features

• No flange or welding for quick install and disconnects. It is slipped over standard weight steel pipe and secured with T-bolt clamps.
• Withstand pressure and vacuum. The maximum temperature is 225 °F.
• Small volume, light weight and good elasticity.
• Good sealing performance.
• High resistance, solvent resistance, weather resistance and radiation resistance.

Applications

Because the rubber joint has good comprehensive properties, so it is widely used in:

• Chemical industry
• Construction
• Water supply
• Drainage
• Circulating water
• Oil
• Infrastructure projects
• Fire protection
• Papermaking
• Pharmaceutical
• Petrochemical
• Shipbuilding
• Water pump
• Compressor fan
• Other piping systems.
