The types of flanges vary in different engineering fields. For example, in the chemical industry, there are two types of standard flanges for chemical equipment: pipe flanges and pressure vessel flanges.Flange connections are widely used in industrial piping. In the home, the pipe diameter is small and low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
