Product Description
Flexible Rubber Expansion Joints DN250 PN10 EPDM Rubber Coupling Joint
Product Introduction
Rubber expansion joints are flexible connectors fabricated from natural and/or synthetic elastomers and fabric, with optional internal metallic reinforcements. Designed to provide stress relief in piping systems, they accommodate thermal movements and mechanical vibrations.
Key Features
- Available in various materials to suit different application requirements
- Capable of absorbing large movements within short distances
- Accommodates multi-directional movement (axial, angular, lateral, torsional)
- Mitigates wind, shock loading, and seismic movements
Advantages
- Excellent compensation for thermal expansion and compression
- Available with flange or threaded connections
- Optional double-bellow design for large movement absorption
- Simultaneously compensates axial, lateral, angular, and transverse movements
- Reduces pipeline tension and protects connected systems from vibration and noise
- Compensates for ground settlement in new buildings
- Provides effective sealing where pipelines pass through walls
