allowable pressure rating for a 2" x 3/4" reducer?
allowable pressure rating for a 2" x 3/4" reducer?
(OP)
Let me first explain the scenario...
Currently, we do Cavern Integrity Tests on underground oil storage caverns periodically. When doing so, nitrogen is purged from the wellhead into a frac tank. Connected to the wellhead is a 2" x 3/4" reducing fitting with internal threads which is immediately connected to a 2" hammer-type coupling and then that is connected to 2" hose into the frac tank.
My question is...I know that the hammer-type coupling is rated at 2000psi, however, since there is a weak part in the system (the location at which the reducing fitting is threaded to the wellhead), will that location as well be rated at 2000psi? The overall system must be rated for at least 2000psi. Help please
Also, the only information stamped onto the reducer is...
2" x 3/4" S/80 A/SA234 WPBN W8297 GT
Does the number of threads come into account?

The reducer is 2" x 3/4" S/80 A234 WPBN with EXTERNAL threads.
How do I determine the MAWP for this fitting?

We have flexible hose rated at 2000psi connected to a hammer-type coupling, which is then connected to the 2" x 3/4" reducer. The individuals heading this want to make sure that the couplings/fittings on either end of the flexible hose are also rated for 2000psi.
So for the 2" x 3/4" Sch. 80 A/SA234 WPB reducer, it is rated for at least 2000psi, including the externally threaded portion?
