Steel flat welded flange DN40 PN16 is a flat, ring-shaped part with holes for bolts and studs, designed for strong connections between pipeline elements. It has a diameter of 40 mm and a nominal pressure of PN16 bars. The flange is manufactured from structural quality steel grade 20 (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1.

These flanges are used to connect pipes of the same or different sizes, as well as various fittings and devices.
