Product Description
Stainless Steel Bellows Expansion Joint Overview
DN25-DN1200 stainless steel bellows flexible metal expansion joint compensators are engineered to absorb dimensional changes in pipelines caused by thermal expansion, contraction, and mechanical displacement. These industrial components provide effective noise reduction and vibration control across various applications.
Product Structure Components
- Bellows: The primary elastic element that absorbs pipeline displacement through expansion and contraction
- End Pipe: Connection component that joins the compensator to pipeline ends
- Bracket: Support and fixation system ensuring operational stability and safety
- Flange: Interface connection with bolted fastening for secure pipeline integration
- Conduit: Flow guidance component directing medium through the compensator system

Key Performance Parameters
| Nominal Diameter (mm) | Wave Number | Pressure Level (MPa) | Effective Area (cm²) | Maximum Outer Diameter (mm) | Length (mm) |
|---|---|---|---|---|---|
| 32-400 | 4-16 | 0.25-2.5 | 16-1611 | 225-700 |
Installation Guidelines
- Verify model, specifications, and pipeline configuration match design requirements before installation
- Ensure inner sleeve direction aligns with medium flow direction for optimal performance
- Remove pre-deformation auxiliary components after pipeline installation completion
- Avoid using compensator deformation to adjust pipeline installation deviations
- Protect bellows surface from welding spatter and mechanical damage during installation
- Remove transportation positioning components and adjust limiting devices to specified positions
- Ensure all moving components operate freely without external obstruction
