EN 1092-1 Type 01 Plate Flanges

Technical Drawing & General Introduction

The EN 1092-1 Type 01 flange is also known as “plate flange for welding”. Usually, it is also called “steel ring flange” or “S/O plate flange”. It is a loose type flange which is very similar to slip on flange but without hub. The Type 01 plate flange can slip onto the pipe prior to 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 buyer’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 tables below. All dimensions are in mm unit and the mass/weight is in kg unit.

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 strip. 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.
