Product Introduction
About this item:
The EN 1092-1 flange Type 01 is also known as the plate welding flange, steel ring flange, or S/O plate flange. It is a loose type flange which is very similar to a slip-on flange but without a hub. The Type 01 plate flange can slip onto the pipe before welding. Two fillet welds, one internal and one external, shall be applied to join the pipe and the flange. They can be furnished with flat face (FF) or raised face (RF) depending on the client's requirement. According to EN 1092-1, Type 01 plate flanges are available in 8 pressure ratings: PN 2.5, PN 6, PN 10, PN 16, PN 25, PN40, PN 63, and PN 100. The dimensions and masses for corresponding flanges are listed in the tables below. All dimensions are in mm and the mass/weight is in kg.
EN 1092-1 Type 01 plate flanges may be made from forgings or flat products (plates). They may be machined from rolled or forged bars and forged section steel. For large sizes, they may be bent and electric welded from bars, section steel, or strips. The flange may be manufactured from a broad spectrum of material grades covering carbon steel, low alloy steel, stainless steel, and other high alloy steels.
