What are the uses of butt welding flange?
Butt welding flange is a kind of pipe fittings, which refers to the flange with neck and transition with round pipe and butt welded with the pipe. The butt welding flange is not easy to deform, well sealed and widely used. It has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition. The distance between the weld junction and the joint surface is large, and the joint surface is protected from welding temperature deformation.

The distance between the weld junction and the joint surface is large, and the joint surface is protected from welding temperature deformation. The butt welding flange adopts a relatively complex bell shaped 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 pipelines and valves with PN greater than 2.5MPa; The butt welding flange is also used in the pipeline conveying expensive, flammable and explosive media. In pipeline engineering, butt welding flange is mainly used for pipeline connection. Install a flange on the pipes that need to be connected. The low-pressure pipes can use threaded flanges, and the pressure above 4kg can use welded flanges Add a gasket between the two flange plates and fasten them with bolts. Butt welding 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 All connecting parts that are bolted and closed around two planes are generally called "flanges", such as the connection of ventilation pipes, which can be called "flange parts" However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, so it is not good to call the water pump a "flange part". Smaller ones, such as valves, can be called "flange parts".
