Stainless Steel Flange Expansion Joint with Metal Bellows

Stainless Steel Flange Connected Expand Flexible Metal Bellow Expansion Joint

A stainless steel flange-connected expandable flexible metal bellows expansion joint is a crucial component in piping systems, designed to absorb thermal expansion, vibrations, and misalignments while maintaining a leak-proof connection.

Key Components & Features:

1.Metal Bellows

Made of stainless steel (SS304, SS316, etc.) for corrosion resistance and durability.

Flexible convolutions allow movement (axial, lateral, angular) to compensate for thermal expansion/contraction.

2.Flange Connection

Typically features ANSI, ASME, DIN, or EN flanges for easy bolting to pipelines.

Ensures a strong, leak-proof seal under pressure.

3.Flexibility & Movement Absorption

Axial Compression/Extension – Handles pipe lengthening/shortening due to temperature changes.

Lateral Offset – Accommodates side-to-side misalignment.

Angular Deflection – Adjusts for minor piping angular shifts.

4.Pressure & Temperature Resistance

Suitable for high-pressure systems (varies by design).

Operates in a wide temperature range (from cryogenic to high heat).

5.Optional Features

Inner liner – Reduces turbulence and erosion.

Cover (shroud) – Protects bellows from external damage.

Limit rods – Prevent over-extension under pressure.

Advantages:
✔ Long service life (resists fatigue and corrosion).
✔ Minimal maintenance (no moving parts).
✔ Reduces stress on pipes, valves, and pumps.
