Features:

Flat welded flange is a type of flange that is directly welded to equipment or pipes through fillet welds. The structure is simple and the processing is convenient. The force characteristics are between the overall flange and the loose flange. The flat welded flange is divided into plate flat welded flange and slip-on flat welded type. The flat welded flange is low in cost and short in production cycle. It is the most commonly used The flange type is widely used in various fluid pipes.
