PTFE Bellows for Lined Pipes
Bellows are specially designed form virgin PTFE and is contour moulded. This manufacturing method guarantess an excellent structure of the material; Symptoms of ageing are practically excluded. Very long term durability and low maintenance costs are assured.
These Bellows are manufactured in different sizes form NB 25mm to NB 500mm. The allowable operating pressures are depending on services conditions. The Bellows can be used upto 200°C.
Bellows serve for compensation of:
- Thermal Strain and Expansion
- Axial and Redial motion
These Bellows are meant for resisting highly corrosive chemicals plants and piping for aggressive medias.
These Bellows are installed in PTFE Lined Carbon Steel Piping and equipment without additional gaskets. For use with piping and equipment made of glass, enamels and ceramics we recommend PTFE Gaskets, offered as accessory.
