Cast Iron Adaptor Bellows Flanges

Cast Iron Adaptor Bellows Flanges are heavy-duty flange components designed to connect PTFE bellows to flanges with non-matching bolt patterns. They act as transition pieces in glass, metal, or modular piping systems, ensuring mechanical alignment, seal integrity, and flexible connection.

The cast iron construction provides exceptional strength, rigidity, and durability, making them ideal for chemical, vacuum, and industrial process systems. These flanges are especially useful in retrofit applications, modular systems, and pilot plants where flange geometry differs.

• Bridges mismatched flange configurations
  
• Rigid support with bellow flexibility
  
• Durable cast iron construction
  
• Customizable dimensions and bolt patterns
  
• Ideal for vacuum, mild pressure, and chemical systems

Cast Iron Adaptor Bellows Flanges Overview

• Adaptor bellow flanges serve as critical interface components in complex piping networks:
• Connect PTFE bellows to flanges with differing bolt patterns or standards
• Maintain mechanical alignment and seal integrity
• Often supplied with split ring inserts for secure sealing
• Minimize misalignment, bending stress, and over-compression of bellows
• Facilitate integration into pre-existing piping or modular glass-to-metal systems
• Cast iron material ensures long-lasting mechanical performance while maintaining rigidity and dimensional stability under operational stresses.

Key Technical Parameters – Cast Iron Adaptor Bellows Flanges

• Material: High-strength cast iron for rigidity and durability
• Bolt Pattern Adaptation: One side matches the bellow flange, the other side can be custom drilled to match non-matching flange standards
• Split Ring Inserts: Supplied with split ring for seal interface
• Undrilled / Optional Drilling: Default undrilled, optional drilling to 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 reduce 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 Cast Iron Adaptor Bellows Flanges

• Connecting PTFE bellows to existing metal flanges with different bolt patterns
  
• Integrating bellows into pre-existing plant piping without re-machining
  
• Supporting modular flexible coupling in glass-to-metal transitions
  
• Retrofitting installations with non-matching flange geometries
  
• Use in vacuum, mild pressure, and chemical systems
  
• Ensuring mechanical alignment, seal integrity, and bellow flexibility

These flanges allow designers to retain bellow benefits while bridging flange mismatches in complex, modular, or retrofit installations.
