Flanschnorm

Flanschnorm is a term used in German-speaking countries to describe the standard sizes and specifications for various mechanical components, particularly those related to flanges. The term is a portmanteau derived from "Flansch," meaning flange, and "Norm," meaning standard. It encompasses a set of technical requirements that ensure interchangeability and compatibility between different parts.

These standards typically cover dimensions such as the diameter of the flange, the bolt circle diameter, the number and size of bolt holes, and the thickness of the flange face. They also often specify sealing surfaces, pressure ratings, and material requirements. Adherence to Flanschnorm facilitates efficient manufacturing, assembly, and maintenance of equipment, especially in industrial settings like piping systems, chemical processing, and machine building.

Different Flanschnorm exist for various applications and regions, such as DIN (Deutsches Institut für Normung) standards in Germany, which are widely adopted internationally. The purpose of these norms is to guarantee that flanges from different manufacturers can be connected without issues, ensuring the integrity and safety of the assembled system. Without such standards, the complexity and cost of engineering and manufacturing would significantly increase.
