Screwed Flange

This is similar to the slip-on Flange in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. The Flange may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing its use in pressure applications.
