Stainless Steel Bellows Flanges

Stainless Steel Bellows Flanges are high-performance flanges designed for PTFE bellow connections in glass, metal, and modular piping systems. They provide a rigid interface while allowing flexible movement, ensuring mechanically stable, leak-proof connections.

Made from premium stainless steel 304/316, these flanges are corrosion-resistant, durable, and suitable for aggressive chemical environments. They are commonly used in chemical, pharmaceutical, and high-purity applications, as well as pilot plants and R&D setups.

• Rigid support for PTFE bellow ends
  
• Superior corrosion resistance for aggressive chemicals
  
• Flexible system compatibility
  
• Precision-machined for leak-proof sealing
  
• Durable under thermal, vibrational, and pressure stresses

Stainless Steel Bellows Flanges Overview

• These flanges serve as critical interface components:
• Connect PTFE bellows to glass, metal, or modular assemblies
• Provide mechanical support without restricting bellow movement
• Include split ring inserts for secure sealing
• Feature distance locking bolt holes to control bellow travel
• Support dynamic piping systems with thermal expansion or vibration

Stainless steel construction ensures resistance to corrosion, chemical attack, and high-temperature processes, making them ideal for demanding industrial environments.
