Technical Specifications

Design and Operating Principle

Vibration absorber expansion joints are designed with high-cycle-life stainless steel metal bellows. The bellows geometry is optimized to absorb equipment-induced vibrations, shocks, and micro-movements.

Single-bellows or multi-bellows design options provide suitable solutions for different vibration levels and operating conditions. Flanged or weld neck connection options allow easy integration into the system.

By reducing the transmission of vibrations and mechanical loads to the pipeline, they minimize stresses at equipment connections and improve overall system stability.

Performance Advantages

• Effectively dampens mechanical vibrations
• Reduces noise levels
• Minimizes stresses in pipeline systems
• Reduces risk of cracking and loosening
• Extends equipment and installation service life
• Ensures safe operation under continuous vibration
• Low maintenance requirement
• Compact and durable structure

Operating Values

Operating Pressure

• Maximum 40 bar
• (depending on DN size, bellows geometry, and number of layers)

Operating Temperature

• -196°C / +550°C
• (depending on bellows material)

Movement Capabilities

• Axial Movement: ±5 mm – 25 mm
• Lateral Movement: ±5 mm – 20 mm
• Angular Movement: ±2° – 6°

Note: Vibration absorber expansion joints are designed with continuous cyclic movements and high fatigue life requirements in mind.
