FLAT FLANGE UNI 2278 DN 15-300 PN10/16

Slip-On Welding Flat Flanges UNI 2278 / UNI 2277 - PN10/16

Slip-on welding flat flanges in carbon steel compliant with UNI 2278 (PN10/16) and UNI 2277 (PN10). The flat flange is the most common and versatile type: it slides over the pipe and is welded with two weld beads (inside and outside). Full range of nominal diameters from DN 15 to DN 300 to cover every system requirement.
