Dimensions of Weld Neck Flanges PN320 EN1092-1 2021/01/03 23:18:11

EN 1092-1 weld neck flange dimension PN320, also known as BS EN1092-1 weld neck flange PN320 standard. EN 1092-1 is the European standard for flanges. Compared with American standard ANSI B16.5 flanges, it is lighter in wall thickness and outer diameter and saves costs. It is widely used in European, African and Middle Eastern markets. The South African standard and the Australian standard draw lessons from the EN1092-1 flange standard on the wall thickness of the flange. EN1092-1 is mainly used in water transmission, oil and mining.
