Threaded Flanges (Screwed flanges) are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges’ pressure applications. Threaded flange use in low pressure condition generally.
Through forging process, using mold forming, and then through machining to complete the product processing.
