3 1/2 Inch Asme B16.9 Threaded Flange are made by machining the inner bore of the flange into a pipe thread and connecting it with a threaded pipe. It is a non-welded flange.
Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed on the site. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, you can also choose a threaded flange.
