According to the degree of integrity of the connection between the flange ring and the straight section, the design is checked according to the integral or loose flange. Compared with the neck welding flange,the plate flange structure is simple, material saving, but the joint performance is not as good as the neck welding flange. Plate flange is a relatively high quality flange products, it reduces the quality and space of the flange, plays an important role in industrial applications.
Plate flanges are widely used to connect medium and low pressure vessels and pipes, and they are suitable for steel tube connections with nominal pressure not exceeding 2.5MPa. The sealing surface of plate flange can be made into smooth, concave and convex and grooved. The application of smooth plate flange is the most. It's mainly used in medium medium conditions, such as low pressure non-purified compressed air or low pressure circulating water.
The types of plate flange contain plate flange, so on flange and plate ring loose flange. As a professional flange supplier, we supply many types flange in different specifications, standards,materials.
