DIN FLANGE

DIN (Deutsches Institut für Normung) flanges are standardized flanges used internationally, particularly in Europe. They are defined by various DIN standards that cover the dimensions, pressure ratings, and materials for different types of flanges. Here’s a comprehensive overview of DIN flanges:DIN Flange Standards1. DIN 25732. DIN 25763. DIN 26334. DIN 26345. DIN 26356. DIN 25277. DIN 25438. DIN 25449.
