Steel Flange BS4504 EN1092-1 DIN

Flange BS4504 PN16 Welding neck A105

British metric standard BS4504 is now obsolete and replaced by EN1092- edition 09-2008 for steel flanges which also incorportes DIN standard. Flange drilling in EN1092-1 are generally teh same as BS4504 and DIN2501 but EN1092--1 covers a wider range. Although BS 4504 is obsolescent, it remains in use for the dimensions of light duty, economy stainless steel flanges in applications where corrosion resistance and hygiene, rather than high pressures and temperatures, are the primary considerations. BS 4504 tables below detail the applicable standard dimensions from PN6, PN10, PN25 and PN40.
