Slip-On Flange Design

Slip-On (SO) flanges feature an inner diameter slightly larger than the pipe's outer diameter, allowing them to slip over pipes easily. Connection is achieved through fillet welding at both the top and bottom of the flange, providing secure attachment while allowing for easier alignment during installation.

  • Shorter length compared to weld neck flanges
  • Ideal for areas with space limitations or short tie-ins
  • Lower initial cost makes them cost-effective for many applications
  • Commonly used in Class 150 and Class 300 utility engineering
  • Suitable for non-corrosive, non-critical, moderate pressure services
Raised Face (RF) Design

The Raised Face design elevates the gasket surface above the bolting circle, allowing for versatile gasket selection including flat ring sheet types and metallic composites like spiral wound and double jacketed types.
