The Dilatation Expansion Joint – Limiting Rod, Welding Neck, PN16 is engineered to ensure reliable protection in pipeline systems by compensating for expansion, contraction, vibration and ground movement.
Its welding neck connection provides high mechanical integrity and eliminates unwanted flange misalignment issues, making it ideal for high-temperature and high-pressure applications.
The internal stainless-steel bellows absorb multi-directional movements, while limiting rods prevent overextension or compression, ensuring stable operation during pressure surges, pump start/stop moments or seismic activity.
This model is widely used in industrial, mechanical and thermal systems that require maximum safety and long-term durability.
