Flanges are also called flanges or flanges. Parts that connect pipes to each other are connected to the ends of pipes. There are holes in the flanges, and bolts make the two flanges closely connected. The flange is sealed with a gasket. Flange is a disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs.
Flanges are divided into threaded flanges, welded flanges and clamping flanges. Flanges are used in pairs. Threaded connecting flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above four kilograms. Add a gasket between the two flanges and fasten it with bolts.
Extended data
Application of flange:
Because of its good comprehensive performance, flanges are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire fighting, electric power, aerospace, shipbuilding and other basic projects.
Application of blind plate:
In the initial start-up preparation stage, when the strength test or tightness test of the pipeline cannot be carried out simultaneously with the connected equipment (such as steam turbine, compressor, gasifier, reactor, etc.). ), equipment and pipeline joint should be set up blind plate.
For all kinds of process material pipelines connected to the battery limit outside the battery limit, when the device stops, if the pipeline is still running, a blind plate is set at the cut-off valve.
