- The threaded flange looks very similar to the sliding flange, but the main difference is that the threaded flange has been drilled to match the inner diameter of a particular pipe.
The rear side of the center opening is then tightened with the conical tube thread of the relevant size. Threaded flanges are used in special cases, the main advantage of which is that they can be connected to the pipe without welding.
Sometimes sealed welds are also used with threaded connections.
Although it is still available for most sizes and pressure levels, today’s threaded fittings are used almost only for smaller pipe sizes. Threaded flanges or fittings are not suitable for piping systems with thinner wall thickness, as it is not possible to cut threads on pipes. Therefore, a thicker wall thickness must be selected at least equal to ASME B36.10 schedule 80
