Flanges are generally designed in accordance with the Japanese Pipe Flange Specification - JIS B 2220-2012. The commonly used flanges of JIS are the plate flat welding flange SOP, the neck flat welding flange SOH, the neck butt welding flange WN and the flange cover BL. Its pressure level is divided into 5K, 10K, 16K, 20K, 30K, 40K, 63K. 16K means about 1.6MPa. Butt welding flange with neck refers to a flange with a neck and a round pipe transition and connected to the pipe butt welding. Butt welding flange is suitable for pipelines with large fluctuations in pressure or temperature or high temperature, high pressure and low temperature pipelines. It is also used in pipelines for conveying expensive, flammable and explosive media.
