Flange Face Types Explained for Forged Applications

Flanges are essential components used to create reliable connections in piping systems across a wide range of industries. One of the critical factors to consider when selecting a flange is the flange face type, which determines the sealing method and affects the overall performance of the connection. Let’s explore four primary flange face types, raised, flat, male & female, and tongue & groove.

Raised Face Flanges

Raised face flanges are the most common flange face type, featuring a raised surface surrounding the bore. This raised surface provides additional sealing pressure, ensuring a tight connection when used with a gasket.

Key Features:

  • Increased sealing pressure
  • Suitable for high-pressure and high-temperature applications
  • Compatible with various gasket materials


  • Oil & Gas industry
  • Power generation
  • Chemical processing

Flat Face Flanges

Flat face flanges have a smooth, flat surface without any raised area, making them ideal for low-pressure applications and non-critical connections.

Key Features:

  • Lower sealing pressure
  • Ideal for low-pressure applications
  • Suitable for use with fragile or brittle materials


  • Water treatment facilities
  • HVAC systems
  • Plumbing installations

Male & Female Flanges

Male & female flanges consist of a pair of flanges, with one featuring a raised (male) surface and the other featuring a recessed (female) surface. When connected, the two flanges form a self-aligning, leak-proof seal.

Key Features:

  • Self-aligning design
  • Enhanced sealing capability
  • Reduced gasket requirements


  • High-pressure and high-temperature systems
  • Subsea pipelines

Tongue & Groove Flanges

Tongue & groove flanges also consist of a pair of flanges, with one featuring a raised tongue and the other featuring a matching groove. When connected, they form a precise, leak-proof seal without the need for a separate gasket.

Key Features:

  • Accurate alignment and sealing
  • Eliminates the need for a separate gasket
  • Ideal for high-pressure applications


  • Chemical processing plants
  • High-pressure steam lines
  • Hydraulic systems
