Metallic expansion bellows

Product Description

Metallic Expansion Bellows are flexible components used in piping systems to absorb thermal expansion, vibrations, and other mechanical movements. They are typically made from stainless steel or other high-grade alloys and are engineered to maintain pressure integrity while accommodating movement.

 Key Functions

 Absorb thermal expansion/contraction

 Isolate vibrations and noise

 Compensate for misalignments

 Relieve system stress

 Main Types of Metallic Expansion Bellows

1. Single Axial Bellows “ Absorbs movement in one axial direction.

2. Universal Bellows “ Two bellows connected by a center pipe; allows axial, lateral, and angular movement.

3. Tied Bellows “ Equipped with tie rods to absorb lateral movements only.

4. Hinged Bellows “ Allows angular movement in a single plane.

5. Gimbal Bellows “ Accommodates angular rotation in multiple planes.

6. Pressure Balanced Bellows “ Compensates for pressure thrust while allowing movement.
