Weight Lists of ASME B16.9 Long Pattern & Short Pattern Stub Ends

Stub ends manufactured to ASME B16.9 can be classified as long pattern or short pattern. A stub end works together with a backing flange (usually lap-joint type) to form an economical assembly, in which the backing flange is made of cheap carbon steel while the wetted stub end may be provided in expensive corrosion-resistant alloys such as stainless steels, nickel alloys, and titanium, etc. Upon requests of many customers, we hereby present the weight values in below lists for ASME B16.9 long-pattern and short-pattern stub ends for NPS 1/2 through NPS 24.
