Stainless Steel Backing Flanges

Stainless Steel Backing Flanges are premium, corrosion-resistant mechanical supports used in glassware coupling systems. These flanges provide structural stability, precise alignment, and leak-proof sealing between glass ends, PTFE bellows, or metal modules.

Crafted from high-quality stainless steel, these flanges are ideal for chemical, pharmaceutical, food & beverage, and pilot plant applications, where corrosion resistance, hygiene, and durability are essential.

• Corrosion-resistant stainless steel construction
  
• Maintains precise alignment of glass components
  
• Ensures mechanical stability under thermal expansion and vibration
  
• Supports vacuum and mild pressure environments

Backing Flanges Overview

• Backing flanges act as core mechanical support elements in glassware systems:
• Join a glass end to another glass component or PTFE bellow
• Provide rigidity and alignment while avoiding stress on fragile glass
• Ensure stable operation under thermal, mechanical, or vibrational stresses
• Essential in modular glass pipelines, pilot plants, and chemical installations

Their robust stainless steel construction makes them suitable for aggressive chemical environments and applications requiring long-term durability.

Key Technical Parameters – Stainless Steel Backing Flanges

• Material: Premium stainless steel for corrosion resistance and strength
• Compatibility: Designed to mate with split-ring inserts and standard flange geometries
• Flange Pattern: Pre-drilled or customizable to match Table E, Table F, ASA 150, or customer specifications
• Mechanical Strength: Withstands axial, bending, and vibrational loads
• Dimensional Options: Available in multiple DN sizes, bolt circle diameters (PCD), bolt holes, and thicknesses
• Insert Use: Paired with split-ring inserts or compatible gaskets for reliable sealing
• Customization: Can supply undrilled or pre-drilled flanges to match mating components

Applications of Stainless Steel Backing Flanges

• Chemical and pharmaceutical glass piping networks
  
• Glass reactors or vessels requiring secure connections
  
• PTFE bellow installations between glass sections
  
• Modular and reconfigurable glass systems
  
• Pilot plants, laboratories, and R&D setups
  
• Repair and retrofitting of existing glass installations

These flanges are used wherever mechanical stability, alignment, and corrosion resistance are critical, particularly under vacuum or mild pressure conditions.
