European standard integral plate flange welded directly to pipe. EN 1092-1 Type 01. DN15-DN1000, PN2.5-PN40. Simple construction for general process piping.
The EN 1092-1 Type 01 Plate Flange is a flat, integral flange with no hub (or a very short hub) that is fillet-welded directly to the pipe. It is the simplest and most economical flange type in the EN 1092-1 series. The weld is placed on both the inner and outer surfaces of the flange, providing a reliable seal for low-to-medium pressure applications.
JIAJI FORGING manufactures Type 01 Plate flanges in austenitic stainless steel, duplex & super duplex (EN 1.4462, 1.4410), and nickel alloys for the global market.
