PTFE High Pressure Expansion Bellow
Product Description:
PTFE High Pressure Expansion Bellow is engineered to compensate for different thermal movements in pipelines and absorb vibrations in the piping during operation.
They help protect fragile process equipment such as glass, plastic, graphite, etc. A bellow is typically made of a series of convolutions designed to compensate axial, lateral and angular deflections.
PTFE Expansion Bellows are available for the entire standard piping range up to 300DN. Heavy-duty bellows with extra convolutions can also be manufactured as per requirement. These bellows are suitable for operation up to 200℃ process temperature.
A special design of PTFE expansion bellows is also available for vacuum applications.
PTFE Expansion Bellows are supplied along with an internal sleeve which supports the convolutions, making it suitable for use in high vacuum applications as well.
Features:
- Compensate for misalignment in piping
- Reduces Mechanical noise due to vibration
- Reduces system stress
- Essential while connecting process equipment of different MOCs
- Heavy Duty bellow with reinforcing rings also available
- Lined bellows also available with wetted parts only of PTFE
Applications:
- Pharmaceutical
- Chemical
- Petrochemical
- Agrochemical
- Food & Beverages
- Petroleum / Refinery
- Process equipments
- Dyes and Pigments
