Round bellows

PTFEaccordion protectioncustom

High flexibility is a characteristic of the bellows with sharp folds of type FS and it is especially well-suited for low pressure stresses and high stroke frequencies. Fold thickness and fold number can be individually adapted to suit customer and application specific requirements. The advantages of this bellows type are a favorable ratio of installation length to elasticity as well as an exceptionally good suitability for dynamic applications. Frequent connection types are flange and cuff connections. Other connection options with customer-specified adaptions are also possible. Areas of applications are expansion and vibration compensation between pipelines, protection of spindles and rods in corrosive atmospheres and in fluid streams. This bellows type is therefore used mainly in chemical and process engineering, in mechanical engineering and in the food and pharmaceutical industry. The operating temperature range is between -120 °C to +150 °C.
