Hexagonal Axial Bellows

Product Description

A Hexagonal Axial Bellows typically refers to a type of expansion joint or flexible bellows used in piping systems to absorb axial movement (compression and extension) while maintaining a hexagonal outer shape for structural or aesthetic purposes.

Heres what it typically contains or consists of:

Convolutions (Bellows Element)

• Material: Usually made of stainless steel or other corrosion-resistant alloys.
• Function: Provides flexibility and allows axial movement by compressing or stretching.
• Shape: The flexible corrugations can be circular internally, even if the outer shape is hexagonal.

End Connections

• Types: Flanged, welded, or threaded ends.
• Purpose: Connects the bellows to the pipeline or equipment.

Reinforcements (Optional)

• Rings or Covers: May be internal or external rings to prevent deformation under pressure or vacuum.
• Hexagonal Casing: In "hexagonal axial bellows," the outer casing or cover may be hexagonally shapedïthis could be structural, protective, or aesthetic.

Liner (Optional)

• Internal Sleeve: Prevents flow-induced vibrations or erosion, especially in high-velocity systems.

Material Composition

Common materials include:

• Stainless Steel (SS304, SS316)
• Inconel
• Hastelloy
• Bronze or Brass (for specific applications)

Gaskets or Seals (in flanged versions)

• Ensures leak-tight connection between the bellows and pipe flanges.

Applications

• HVAC systems
• Industrial piping
• Exhaust systems
• Chemical and petrochemical industries
