Product Description
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
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
Flange Connection
- Typically features ANSI, ASME, DIN, or EN flanges for easy bolting to pipelines
- Ensures a strong, leak-proof seal under pressure
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
Pressure & Temperature Resistance
- Suitable for high-pressure systems (varies by design)
- Operates in a wide temperature range (from cryogenic to high heat)
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
