Features
- FAF External Pressurized Expansion Joints are preferred in long pipelines in order to use less number of expansion joints used and to reduce number of fixed points and roller bearing that increase installation costs.
- Rotary Flange or welding end is produced in the joints.
- Absorbs high amounts of expansion consists of thermal difference.
- With the help of pressure balance maintaned through fluid pressure affecting the outer bellow, sprain possibility on the bellow is prevented.
- Since bellow is solated from environment is not affected bt external forces.
- Twists that may occur is eliminated via pressure balance which is provided by fluid pressure to influence the outer surface of the bellows.
- Due to isolated from external environment the risk of impairment is put away because of external factors.
- Additionally they are favourable to be used for fluids like boiling oil in which high safety factors are preferred.
- Large amounts of axial movement can now be absorbed using a long bellows that would have otherwise squirmed.
- As assembly aids for pumps, fittings and plate heat exchangers.
- Expansion joints are used in lots of applications, where it concerns safety, health, environment, durability and lifetime. Bellows are made from stainless steel strip which is first welded to a thin walled tube and formed to a bellow afterwards.
- It can be manufactured as rotary flanges (FAF5411), welding ends (FAF5421)
- Stock piled for quick delivery.
