1. A tap assembly that attaches at least one of a manifold and pressure transmitter to an orifice, the tap assembly consisting essentially of:
- (a) a tap having an exterior surface, a male NPT threaded end, and a flanged end;
(b) a separate stabilizing tube having an internal bore contiguous the exterior surface of the tap and an outer surface with external threads; and
(c) a stabilizing nut threaded on the external threads of the separate stabilizing tube.

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).

5. A method of attaching a tap to an orifice, the tap including a male NPT threaded end, a flanged end, the tap having a bore extending between the male NPT threaded end and the flanged end, the method comprising:
-
disposing the threaded end of the tap in the orifice; surrounding a portion of the tap with at least one member; engaging a first end surface of the at least one member with an area proximate the orifice; and abutting a second end surface of the at least one member with the tap. - View Dependent Claims (6, 7)
