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