A full range of PN40 raised face weld neck flanges is available here on our website, these type 11 flanges all conform to the BS EN 1092-1:2018 and have been previously known as BS 4504 as well as metric flanges. We offer forged PN40 weld neck flanges from stock in sizes 1/2" (15mm) to 6 5/8” (168mm) nominal bore.

All of our PN40 weld neck flanges come with a raised face which increases pressure on the gasket for a stronger seal, they also come with 3.1 mill test certification on request. All of our BS EN 1092-1 flanges are forged from S235JR mild steel.
