Main characteristics and purpose of products

Bellows expansion joints are an assembly used as compensating elements for thermal strain damping of pipelines delivering hot and cold materials, flexible inlets of overhead tanks, etc. They are also used for the connection of pressure and suction pipelines to units (pumps, turbines, compressors, engines etc.) installed on resilient mounts to reduce vibration.

Bellows expansion joints are waterproof, vacuum-tight, temperature-stable, reliable in operation and maintenance-free during the entire service life.
