BS EN 1092-1 Slip On Bossed Flanges

We offer an extensive range of type 12 raised face slip-on bossed welding forged flanges to BS EN 1092-1:2018 from stock, these were previously known as metric or BS 4504 flanges and are available here on our website in sizes between 1/2" (15mm) and 12" (300mm) nominal bore. All of our EN 1092-1 slip-on flanges are made of S235JR mild steel and come with a raised face which increases pressure on the gasket for a strong seal, this type of pipe flange is often fillet welded directly to the ends of steel pipe and tube.

We can supply these welding flanges with PN6, PN16 & PN40 pressure ratings, temperature ratings vary but are linked to the pressure rating of the flange.
