Selection and design of threaded flange

　　Threaded flange is a kind of flange which uses thread to connect with pipeline. In design, it can be treated as loose flange. The advantage is that there is no need for welding, and the additional torque to the cylinder or pipe is very small when the flange is deformed. The disadvantage is that the flange thickness is large and the cost is high. Suitable for connection of high pressure pipeline.

　　A105 Carbon Steel Threaded Flange is a kind of non welding flange, which processes the inner hole of flange into pipe thread and realizes the connection with the pipe with thread. Compared with the flat welding flange or butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines that are not allowed to be welded on site. The alloy steel flange has enough strength, but it is not easy to weld, or the welding performance is not good, the threaded flange can also be selected.
