Welded flange is bored to match the inside diameter of the mating pipe or fitting to ensure uninterrupted flow. This prevents turbulence at the joint and reduces erosion. It also provides excellent stress distribution through the tapered hub and is easily radiographed for flaw detection. It is welded to a pipe or fitting with a single full penetration.

Flanges are mainly used to connect valves, pumps and pipes to make a complete piping system. Flanges are classified into three types based on faces, Raised Face (RF), Flat Face (FF) and Ring-Type Joint Face (RTJ). The most commonly used type is Raised Face flange. Flanges can be connected to the piping system either welded or screwed. Flanged joints are fixed by bolting together, with a gasket in between where as required.
