Product Description
Plate flange refers to a flange connected with a container or pipe by a fillet weld. It is an arbitrary flange. According to the integrity of the connection between the flange ring and the straight barrel section, the design is checked according to the integral or loose flange. There are two kinds of flange rings with neck and without neck. Compared with the neck butt welded flange, the flat welded flange has simple structure and less material, but the stiffness and sealing property are not as good as that of the neck butt welded flange. Flat welded flange is widely used in the connection of medium and low pressure vessels and pipelines.

Advantages and disadvantages
The advantages of flat welded flanges include simple production, low cost, easy installation, and suitable for a variety of different media and pressure requirements. However, its disadvantage is poor rigidity, not suitable for supply and demand, flammable, explosive and high vacuum requirements.
Structural characteristics
The structure of the flat welded flange is characterized by the flange and the pipeline through welding, and the welding position is generally at the port of the pipeline. The flat welded flange is divided into flat welded flange with neck and plate welded flange two types.
Application scenario
The flat welded flange is suitable for the pipeline system with low pressure grade, little pressure fluctuation, and no serious vibration and shock. Because of its cheap price, it is often used in the case of moderate medium conditions, such as low pressure unpurified compressed air, low pressure circulating water and so on.
