What Are the Dimensions and Standards of Stainless Steel Flanges?
Flanges are important connecting elements widely used in industrial applications for joining pipelines. Offering high corrosion resistance, durability, and long service life, flanges are especially preferred in the chemical, food, energy, and petrochemical sectors. So, what are the dimensions and standards of stainless steel flanges?

Stainless Steel Flange Standards

They are manufactured according to international standards. The most commonly used standards are:

• ANSI/ASME B16.5: Flanges produced according to American standards are available in diameters ranging from ½” to 24″.
• DIN: Flanges manufactured according to German standards are especially common in Europe.
• EN 1092-1: Covers flange dimensions in compliance with European Union standards.
• JIS: Flanges manufactured according to Japanese Industrial Standards.
• ISO: Flange types that comply with international standards.

Dimensions

Flange dimensions vary depending on their intended use and applicable standards. The basic measurements are as follows:

• Nominal Diameter (DN): Refers to the inner diameter of the pipe to which the flange will be connected (e.g., DN50, DN100).
• Pressure Rating (PN): Indicates the maximum pressure the flange can withstand (e.g., PN6, PN10, PN16, PN25, PN40).
• Number and Diameter of Bolt Holes: The number of bolt holes on the flange for connections and the diameter of these holes.
• Flange Thickness: The body thickness of the flange, which varies depending on the material and pressure rating.

Types of Flanges

• Flat Face Flange (FF)
• Raised Face Flange (RF)
• Threaded Flange
  
  
• Weld Neck Flange
• Loose Flange
