Background:
The butt welding flange is not easy to deform, has good sealing and is widely used. It has corresponding rigid and elastic requirements and reasonable butt welding thinning transition. The distance between the weld junction and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a relatively complex horn shape structure, which is suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, It is generally used for the connection of pipes and valves with PN greater than 2.5MPa; It is also used for pipelines conveying expensive, flammable and explosive media.
Marking and Use
In pipeline engineering, flange is mainly used for pipeline connection A flange shall be installed for all kinds of pipes to be connected. Threaded flanges can be used for low-pressure pipes, and welded flanges can be used for pressure above 4kg Add a gasket between the two flanges and fasten them with bolts Flanges with different pressures have different thicknesses and use different bolts When pumps and valves are connected with pipes, parts of these equipment are also made into corresponding flange shapes, also known as flange connection The connecting parts that are bolted on two planes and closed at the same time are generally called "flange", such as the connection of ventilation pipe. This kind of parts can be called "flange parts" However, this connection is only a part of the equipment, such as the connection between flange and water pump, so it is not good to call the water pump "flange parts" Relatively small, such as valves, can be called "flange parts"
