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.
