Pressure vessel flanges are divided into flange flanges: integral flanges, looper flanges and arbitrary flanges. The most commonly used pressure vessel flanges in China are divided into flange flanges: integral flanges, loose flanges and free-form flanges. There are three types of JB / T4701-4703 standard pressure vessel flanges most commonly used in China: Type A flat welding flange, Type B flat welding flange and long neck butt welding flange, of which Type A and Type B flat welding flange All belong to arbitrary flanges. Flange and its gaskets and fasteners are collectively referred to as flange joints. Flange joints are a kind of parts that are widely used in engineering design and involve a wide range of areas. They are also key parts that are prone to problems during engineering design and use. . Flange joint design is one of the important contents in the design of pressure vessels. In the selection of standard A-type flanges and calculation of non-standard A-type flanges, designers choose materials that are unreasonable. The use of B-type flat welded flanges or even long-neck butt-welded flanges instead of There are also many situations, causing unnecessary waste. Therefore, it is necessary to discuss the selection and calculation of common A-type flat welding flanges.

In the selection of standard A-type flanges and calculation of non-standard A-type flanges, designers choose materials that are unreasonable. It is more serious to use B-type flat welding flanges or even long-neck butt-welding flanges instead of A-type flat welding flanges. There are also many situations, causing unnecessary waste. Therefore, it is necessary to discuss the selection and calculation of common A-type flat welding flanges.
