DN200 Floating Flanged Single Sphere Rubber Expansion Joint
DN50-DN1200
The DN200 Floating Flanged Single Sphere Rubber Expansion Joint is a precision-engineered, flexible pipe connector designed to absorb multi-directional stress and movement in industrial piping systems. By providing effective stress relief, it mitigates the risk of equipment failure, reduces maintenance costs, and extends the operational lifespan of your entire system. Its unrestrained design makes it particularly suitable for applications requiring vibration absorption, noise reduction, and compensation for thermal expansion, pipe misalignment, or ground settlement.

**Key Engineering Benefits & Features**
- **Superior Multi-Directional Movement Capability** – The joint's spherical single-arch geometry efficiently absorbs axial compression and extension (caused by thermal expansion and contraction), lateral offset (from pipe settlement or misalignment), and angular deflection, effectively preventing stress concentration at pipe connections.
- **"Floating"Flanges for Easy Installation** – A key distinguishing feature is the ductile iron floating flange, which can rotate 360° independently of the rubber body. This eliminates the need for precise bolt-hole alignment during installation, significantly reducing labor time and simplifying the mating process with existing pipe flanges. The flanges follow the Vanstone profile design, ensuring superior compatibility with standard piping systems.
- **Superior Vibration and Noise Dampening** – The inherent damping properties of EPDM rubber effectively isolate and dissipate energy generated by pumps, compressors, and chillers. This makes the joint an essential component for HVAC systems in noise-sensitive environments such as hospitals, hotels, and commercial buildings, as well as in various industrial processing plants.
- **Robust, Reinforced Construction for Durability** – Built for long-term service under pressure, the joint features multiple layers of high-tensile nylon cord fabric embedded within the EPDM rubber body. This reinforcement provides exceptional burst resistance and ensures dimensional stability even under vacuum conditions, guaranteeing reliable performance over an extended service life.
