Universal Expansion Bellows

उत्पाद वर्णन

Universal Expansion Bellows" typically contain or consist of the following components and materials:

Key Components:

1. Bellows Element:

   • The flexible core of the unit that absorbs movement.

   • Usually made from stainless steel (e.g., SS 304, 316L).

2. End Fittings:

   • Weld ends, flanges, or threaded connections.

   • Match the pipe or system connection type.

3. Internal Sleeve (Liner) (optional):

   • Protects the bellows from media flow erosion or turbulence.

   • Helps reduce pressure drop.

4. External Cover (Shroud) (optional):

   • For protection from external damage or insulation.

5. Tie Rods / Limit Rods (in some designs):

   • To control the axial or lateral movement and avoid overextension.

6. Reinforcement Rings (optional):

   • For high-pressure applications.

Materials Typically Used:

• Metal Bellows: Stainless Steel (SS 304, SS 316, Inconel, Hastelloy, etc.)

• End Fittings: Carbon steel, Stainless steel, Alloy steel

• Sleeve & Cover: Stainless steel or same as bellows

• Tie Rods: Carbon steel or stainless steel

What It Contains Functionally:

A universal expansion bellow is designed to absorb multi-directional movement:

• Axial
