Aluminium Bellows Flanges

Aluminium Bellows Flanges are precision-engineered flange components designed to connect PTFE bellows in glass, metal, and modular piping systems. These flanges provide a rigid interface while allowing flexible movement, ensuring mechanically stable, leak-proof connections.

The lightweight nature of aluminium makes these flanges ideal for systems where reducing structural load is important, while still providing mechanical strength and corrosion resistance.

• Lightweight yet strong support for PTFE bellow ends
  
• High corrosion resistance for chemical and industrial processes
  
• Flexible system compatibility
  
• Precision-machined for leak-proof sealing
  
• Durable under thermal, vibrational, and mild pressure stresses

Aluminium Bellows Flanges Overview

• Aluminium bellows flanges serve as critical interface components in flexible piping systems:
• Connect PTFE bellows to glass, metal, or modular assemblies
• Provide mechanical support while maintaining flexibility
• Include split ring inserts for a secure sealing interface
• Feature distance locking holes to control bellow travel
• Ideal for pilot plants, R&D labs, and modular systems where weight reduction is important

Aluminium construction ensures resistance to corrosion, moderate chemical attack, and ease of handling, making them suitable for light-duty and dynamic process systems.
