Some pipe fittings and equipment have their own flange, but also belong to flange connection. Flange connection is an important connection way for pipeline construction. Flange connection, easy to use, able to withstand greater pressure. Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.
Q:Where is the flange used in the pump?
