Flanges DIN

Across the pond, you will find the Deutsches Institut für Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a DIN flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME steel flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.

The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck flanges, and blind flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.

It is the official German national organization responsible for developing and publishing standards for a vast range of products, services, and processes. While DIN standards originated in Germany, they are highly respected and widely used internationally, particularly throughout Europe.

When a product is "DIN compliant," it means manufactured to exact specifications of a particular DIN code (e.g., DIN 2576 or DIN 2633). Standards define:

• Dimensions and Tolerances: Bolt hole size and placement, flange diameter, thickness
• Material Specifications: Types of steel or alloys
• Pressure-Temperature Ratings: Maximum pressures at specific temperatures
