The Metal Bellows Expansion Joint With Limiting Rods (PN16) is engineered to protect pipelines against movement caused by thermal expansion, pressure fluctuations, vibration and ground-based seismic activity. The limiting rods act as a mechanical safety system, preventing excessive axial extension and ensuring controlled movement within preset limits.
Constructed with stainless steel bellows and ductile iron flanged ends, this expansion joint offers superior durability, corrosion resistance and long service life, even in demanding industrial environments.
Limit rod systems are essential in high-pressure lines, pump discharge lines and applications where unrestrained expansion joints could cause mechanical stress or misalignment.
