Butt Welded Connections(BW) : A butt-weld connection is made by welding the beveled ends of the pipe and straight end of the valve together. Weld along a seam that is butted edge to edge. Beveled ends(BE) indicate that the ends of the pipe lengths of the valve are not cut square, but rather are cut or ground to have a tapered edge.

BW Ends are as specifications of ANSI B16.25 or related international standard.
