ABSTRACT:
A method and apparatus are directed to reduce the load from the threads on taps on an orifice plate or orifice fitting. The apparatus includes a tap (3) having an NPT threaded end (1) and a flanged end (12) and an intermediate flange (13) which engages with a stabilizing tube (2) placed around the tap (3). In use, a stabilizing nut (1), previously threaded on the stabilizing tube (2), is unthreaded thereby forcing the stabilizing tube (2) against the intermediate flange (13) and transferring at least some of the weight off the threads (1) of the tap (3).
