Stainless steel flange is a kind of disc type part, which is widely used in pipe network engineering. Flanges are all applied in pairs. In the pipeline network project, the key to the production and processing of stainless steel flanges is to connect the pipelines. A variety of flanges are installed in the pipelines that must be connected. The bottom pressure pipeline can be connected to the flange. The welding flange should be used for working pressures above 4Kg. Add a sealing point between the two flanges, and then tighten it with anchor bolts. Flanges with different working pressures have different thicknesses and different applications of anchor bolts.
When the centrifugal water pump and gate valve are connected to the pipeline, the equipment and machinery parts are made into corresponding stainless steel flanges, also called loose flanges. Anything that uses screws to connect closed connection parts near two plan views is called a "flange," such as the connection of a ventilation duct, this type of part is called a "flange type part." This type of connection is only part of the machinery and equipment. The relationship between the flange and the centrifugal water pump makes it difficult to call the centrifugal water pump "flange parts." Smaller and medium-sized ones, such as gate valves, can be called "flange-type parts."
1. Connect the pipeline and maintain the sealing characteristics of the pipeline.
2. The stainless steel flange facilitates the disassembly and replacement of a section of the pipeline.
3. The stainless steel flange facilitates the disassembly and inspection of the pipeline condition.
4. The stainless steel flange is conducive to the closed section of a pipeline.
Common problems in the method of loose flange fittings. The connection of flanges is to fix two pipelines, pipes, or instruments on one flange piece, respectively, and then add flange pads between the two flange pieces. Tighten together with anchor bolts to complete the connection. Some pipes and instruments have built-in flanges, also attributed to loose flanges. Looper flange is the key interface method for pipeline engineering construction. The loose flange is easy to use and can bear great working pressure. In industrial pipelines, the application of loose flanges is widespread. In the home, the pipe diameter is small, and the bottom pressure is so that the loose flange is not visible. There are pipes and equipment with loose flanges everywhere, if it is in a boiler room or on the manufacturing site.
According to the interface mode, the type of loose flange fittings can be divided into flat welding flange, flat welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, butt joint with neck Welding ring loose flange, flat welding ring loose flange, ring groove face flange, and flange cover, large-diameter tablet computer flange, large diameter high neck flange, eight-shaped blind plate valve, butt welding ring Loose flanges, etc.
