Metal bellows is a widely used flexible connecting element in industrial fields, primarily used to compensate for displacement, vibration, and thermal expansion in piping systems.
The following key factors should be considered when selecting a model:
1. Material Selection: Choose materials such as stainless steel, carbon steel, or alloy steel based on the characteristics of the medium to ensure corrosion resistance and temperature resistance.
2. Pressure Rating: The working pressure should be lower than the rated pressure of the bellows, and a safety factor should be considered.
3. Displacement Compensation: Axial, lateral, and angular displacements must match the actual operating conditions.
4. Size Specifications: The nominal diameter should match the pipeline, while considering installation space limitations.
5. Connection Method: Flange connections, welding, or quick couplings must be compatible with the system.
