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).

8. A method of transferring the load on the threads of a pressure tap to a larger area than just the threads of the pressure tap, said method comprising:
-
(a) providing a tap having at one end, male NPT threads and at the other end a flange and immediate thereto a stabilizing flange;
(b) providing a threaded stabilizing tube;
(c) threading a stabilizing nut on said stabilizing tube;
(d) threading said NPT threads into a source of pressure; and
(e) unthreading said stabilizing nut on said stabilizing tube to expand the stabilizing tube and stabilizing nut into a state of compression thereby transferring at least some of the load from the NPT threads to the stabilizing flange. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
