High-performance Universal Bellows Compensator for Thermal Expansion & Mechanical Movement Absorption
16"-80"
This DN700 Universal Metal Bellows Expansion Joint is a high-performance, engineered piping component designed to absorb multi-directional movement while containing pressure thrust internally . It is constructed with one or more stainless steel bellows elements and a robust system of tie rods , making it a "tied" or "pressure balanced" universal joint. This design is essential for applications where anchoring or guiding the pipeline is impractical or where the pressure thrust force must be eliminated from the connected equipment and pipe guides.

Product Description
Product Description:
This DN700 Universal Metal Bellows Expansion Joint is a high-performance, engineered piping component designed to absorb multi-directional movement while containing pressure thrust internally . It is constructed with one or more stainless steel bellows elements and a robust system of tie rods , making it a"tied"or"pressure balanced"universal joint. This design is essential for applications where anchoring or guiding the pipeline is impractical or where the pressure thrust force must be eliminated from the connected equipment and pipe guides.
Key Features & Design Advantages:
1. Multi-Directional Movement Absorption:
* Universal Design: Capable of absorbing lateral (shear) , angular , and axial movements in any plane, providing exceptional flexibility for complex piping layouts.
2. Internal Pressure Thrust Containment:
* Tie Rod System: The integrated tie rods, equipped with limit nuts, are designed to absorb the pressure thrust force (end force from pressure) and prevent it from being transmitted to adjacent equipment (e.g., pumps, turbines) or pipe anchors. This protects critical infrastructure.
3. High-Performance Bellows:
* Material: Manufactured from high-grade austenitic stainless steel (e.g., SS316/316L) for excellent corrosion resistance, fatigue life, and temperature tolerance.
* Construction: Multi-ply bellows design (typically 2 or 3 plies) is standard for DN700 to provide higher pressure ratings and improved safety.
4. Robust Hardware:
* Heavy-Duty Tie Rods & Nuts: Made from carbon or alloy steel, sized to withstand the full pressure thrust load.
* Piping Flanges/End Connections: Carbon steel flanges (ANS150#/PN16 standard or custom), precisely machined for easy bolting and leak-free installation.
* Internal Liner (Optional): Available to protect the bellows from turbulent flow, vibration, and media ingress (debris), extending service life.
5. Safety & Longevity:
* Leak-Tight Integrity: Ensures zero leakage of process media.
* Extended Cycle Life: Engineered to withstand hundreds of thousands of movement cycles for reliable, long-term operation.
* Pre-Assembled & Tested: Factory pre-tensioned and 100% pressure tested to ensure performance and safety.
