Product Description
Rubber Expansion Joint (DN80)

PTFE Bellows/Expansion Joint

To compensate for length changes in pipelines expansion bends, stuffing box compensators or expansion bellows are used. Bellows have proved particulaly suitable for lined pipe which may be subjected to shock and vibration. They also accomodate axial misalignment. Further advantages include simple space-saving design and speedy installation. 

Typical Applications:
Chemical Engineering-PTFE is employed in all cases where corrosive substances are used and where conventional materials create sealing problems. Glass apparatus is an example. In this type of equipment, PTFE is used for expansion bellows, which are designed to compensate for mechanical and thermal changes, flexible tubing, seals, glandless valves, turbine stirrers, etc.
