Construction
Parts and materials
Compensator bellows lined DNOVA CB-3232P-F is designed to reduce vibration and noise arising in pipelines due to the operation of pumps or other equipment, as well as to compensate for temperature displacements of the pipeline. The bellows, which is a corrugated elastic asymmetric shell made of metal alloy, coated inside with polytetrafluoroethylene PTFE, compensates axial displacements due to its flexibility. Under the action of transverse, longitudinal forces, bending moments and angles of rotation, the component structure has the ability to stretch and shrink, bend and change its shape in the transverse direction. PTFE material is a non-flammable component, practically unaffected by various chemical media, resistant to a wide range of temperatures.
