Rubber Expansion Joints with GI Flanges
Rubber Expansion Joints with GI Flanges
Flexible Vibration Isolators for Oilfield, Marine & Civil Engineering Applications
✅ What Are Rubber Expansion Joints?
Rubber Expansion Joints are flexible connectors made from natural or synthetic elastomers and reinforced with fabric or metal. They are designed to absorb vibration, compensate for misalignment, reduce noise, and relieve system strain caused by thermal movement or pressure surges.
When paired with Galvanized Iron (GI) Flanges, these joints offer corrosion resistance, ease of installation, and secure bolted connections—making them ideal for high-performance industrial applications.
