What is a flange?

Flanges are disc-shaped parts that are most common in plumbing and flanges are used in pairs. In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed, and the low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. A sealing point is added between the two flanges and then fastened with bolts. Different pressure flanges have different thicknesses and use different bolts. Pumps and valves, when connected to the pipe, are also made of corresponding flange shapes, also known as flange connections. Connection parts that are closed at the same time by bolting on both planes are generally referred to as "flanges". For example, the connection of ventilation ducts may be referred to as "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 pump "flange parts". Smaller such as valves, etc., can be called "flange parts".

 

What is the connection method of the flange?
 

Flange connection is an important connection method for pipeline construction.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange, and between the two flanges, with flange pads, bolted together to complete the connection. Some fittings and equipment have their own flanges and are also flanged.

Flange threaded connection (wire connection) flange and welded flange. Low-pressure small-diameter wire-bonded flanges, high-pressure and low-pressure large diameters are all welded flanges. The thickness of the flanges of different pressures and the diameter and number of connecting bolts are different.

Depending on the level of pressure, the flange pads are also available in different materials, from low pressure asbestos pads, high pressure asbestos pads to metal pads.

The flange connection is easy to use and can withstand large pressures.

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. Flange connection is to fix two pipes, pipe fittings or equipment on a flange, and between the two flanges, with flange pads, bolted together to complete the connection. Some fittings and equipment have their own flanges and are also flanged.

Pay attention to the fact that all bolts are tight when connecting, especially when the bolts are tightened.
