What is the function of the flange stub?!

Answer:

In pipe engineering, flanges are used mainly for pipe connections. In the need to connect the pipe, all kinds of installation of a flange, low pressure pipe can use wire connection flange, more than 4 kilograms pressure use welding flange. Seal points between the two flanges, then fasten with bolts.
Different pressure flanges have different thicknesses and use different bolts. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. In the two plane in the vicinity of the use of bolted connections, and closed parts are generally referred to as "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts."". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
Flange is a kind of discoid parts, which is the most common in pipeline engineering. The edge has bolted mechanical structures, such as pipe joints, which can be bolted if flanges are attached to the flange. The flange cap is the flange of the cap and is bolted to the flange. Flanges are used in pairs.
