As pipe flanges for different industrial applications, threaded flanges are widely demanded. They are special types of pipe flanges that can be attached to the pipe without welding. Threaded flanges are threaded in the bore to match the external threads on the pipe.

The threaded flange is tapered to create a seal between the threaded flange and the pipe as the taper approaches the same diameter. Seal welds are sometimes used in conjunction with threaded connections. They are available in a variety of sizes and materials.
