The part number decodes as follows: WE = Windlass brand, SHU = hammer union, 100 = Figure 100 pressure class (1,000 PSI CWP), 3 inch pipe size (DN 25), BW = buttweld end connection. FIG 100 hammer unions conform to industry-standard Figure 100 geometry, featuring a three-lug wing nut body (visible in photos, cast iron\/ductile iron construction with yellow-painted seating surfaces) and a threaded wing nut that draws two pipe sections together via the hammer lugs — designed to be made up and broken out quickly using a hammer. The buttweld end connection means both the sub and nipple ends are prepared for butt welding directly to Schedule 40 pipe. Typical applications include oilfield flowlines, production manifolds, frac water transfer, and general industrial piping systems where quick-disconnect service at moderate pressure is required. The Windlass brand marking and \"1000 CWP\" rating are clearly cast into the wing nut face as confirmed in the product photos.
