Abstract: A pulsation and acoustic energy reduction dampener (200) for installation within well piping between a standpipe (110) and a swivel (116) includes a body (201, 202) formed from a union connection sub (202) providing a threaded male connection at one end of the body and welded to a union connection nut (201) providing a threaded female connection at the other end, each for connection to the well piping (203, 204). A flow restriction orifice assembly (205, 206) is secured by welding or gluing within the union connection sub and includes a replaceable wear component (206) such as an annular ceramic insert with a tapered or cylindrical interior through-hole.
