ASME/ANSI B16.5 1500 Class Threaded Flange/Standards, Dimensions & Weight

Threaded Flanges, also known as Screwed flanges, have a similar outline to slip-on flanges, but with a threaded bore that allows for assembly without welding. However, this limits their use to relatively low-pressure piping systems. While Threaded Flanges can be welded around the joint after assembly, this method is not recommended for increasing their pressure applications. Typically, Threaded Flanges are used in low-pressure conditions.
