Flange is a disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs and with matching flanges on valves. In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, various flanges are installed. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. Add a gasket between the two flanges and fasten them with bolts. Different pressure flanges have different thicknesses and use different bolts.

main effect

1. Connect the pipeline and maintain the sealing performance of the pipeline;

2. It is convenient to replace a certain section of pipeline;

3. It is easy to disassemble and check the pipeline condition;

4. It is convenient for the sealing of a certain section of pipeline.

Flange Features

Flange (flange is also called flange or flange. It is the part that connects the pipe to the pipe. It is connected to the end of the pipe. There are holes on the flange, which can be bolted to make the two flanges tightly connected. A gasket is used between the flanges. Seal. Flanged pipe fittings (flanged pipe fittings) refer to pipe fittings with flanges (flanges or discs). It can be cast, threaded or welded. Flange (flange, joint) is composed of a pair of methods It is composed of a flange, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nuts are tightened, the specific pressure on the gasket surface will deform after reaching a certain value, and fill the unevenness on the sealing surface. The connection is tight and leak-proof. Some pipe fittings and equipment already have their own flanges, which are also flange connections. Flange connections are an important connection method in pipeline construction.

Flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small, and it is 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.
