Adaptor Bellows Flanges

Adaptor Bellows Flanges are precision-engineered cast iron components designed to connect PTFE bellows to flanges with differing bolt patterns or standards. These flanges act as transition pieces, bridging mismatched interfaces in glass, metal, and modular piping systems.

They provide rigid mechanical support while maintaining the flexibility of PTFE bellows, ensuring structural stability, leak-proof sealing, and alignment integrity.

• Bridges mismatched flange configurations
  
• Maintains bellow flexibility
  
• Rigid mechanical support with minimal stress on components
  
• Customizable dimensions and bolt patterns
  
• Ideal for vacuum, mild pressure, and chemical systems

Adaptor Bellows Flanges Overview

• Adaptor bellow flanges serve as critical interface components in complex piping systems:
• Connect PTFE bellows to flanges of non-matching bolt configurations
• Act as transition pieces in coupling assemblies
• Often supplied with split ring inserts for secure sealing
• Reduce misalignment and bending stress on the connected bellows
• Allow integration into existing plant piping or modular glass-to-metal systems

Cast iron construction ensures mechanical strength, rigidity, and long-term reliability, while optional custom drilling enables perfect mating with any standard flange.

Key Technical Parameters – Adaptor Bellows Flanges

• Material Options: Cast iron for mechanical strength and rigidity
• Bolt Pattern Adaptation: One side matches the bellow flange; the other side can be drilled to match a different flange standard
• Split Ring Feature: Supplied with split ring insert for seal interface
• Undrilled / Optional Drilling: Default undrilled; customers can request custom flange drilling (Table E, Table F, ASA 150)
• Dimensional Coverage: Available in multiple nominal diameters, with corresponding outer diameters, thickness, and bolt hole circles
• Mechanical Alignment: Designed to minimize misalignment and bending stress on bellows and mating flanges
• Customization: Adaptable for specific process or equipment requirements
• Temperature & Pressure Compatibility: Suitable for vacuum, mild pressure, and reactive chemical environments

Applications of Adaptor Bellows Flanges

• Connecting PTFE bellows to existing metal flanges with differing bolt patterns
  
• Integrating bellows into pre-existing plant piping without re-machining mating flanges
  
• Supporting modular flexible coupling in glass-to-metal transitions
  
• Retrofitting installations where flange geometries do not align
  
• Use in vacuum, pressure, or reactive chemical systems requiring bellow flexibility
  
• Ensuring mechanical alignment and seal integrity in complex systems

These adaptors retain the functional benefits of bellows flexibility while accommodating flange mismatches, making them essential in modular, retrofit, and high-precision installations.
