A brief discussion of these classifications of flanges
Speaking of flanges, I don’t know if you are unfamiliar with it, but for friends who know the pipe fittings industry, flanges are very familiar with pipe fittings. Flanges are parts that connect pipes to each other and are used between pipe ends. Connections are sometimes used to connect equipment. There are many ways to classify flanges. I believe it may be difficult for some friends to know all the connection methods even if they understand the pipe fitting industry. Today we will learn about flanges. How many ways of classification are there.
