slip on flange production processing
When water pumps and valves are connected with pipelines, parts of these equipments are also made into corresponding flange shapes, which are also called flange connections. All connecting parts that are connected by bolts on the periphery of two planes at the same time are generally called "flanges", such as the connection of ventilation pipes. This type of parts can be called "flange parts".
However, this connection is only a part of the equipment, such as the connection between the flange and the water pump. It is not good to call the water pump "flange parts". Smaller ones, such as valves, can be called "flange parts".
