1. A flange adapter assembly, comprising:
an inlet flange member having bolt recesses forming a bolting pattern and a centralized conduit for directing pressurized fluid therethrough;
an outlet flange member having bolt recesses and a centralized conduit for relieving pressurized fluid therethrough, the bolt recesses and centralized conduit of the outlet flange member corresponding with those of the inlet flange member;
a pressure containing member configured to be sealingly engaged between the inlet flange member and the outlet flange member, the pressure containing member further configured to fit entirely within a circle formed by the bolting pattern, the pressure containing member having a cylindrical bore defining a central axis;
an insert device; and
a flange adapter configured to be selectively connected to the pressure containing member, the flange adapter having a central opening defining an internal perimeter boundary and an exterior perimeter shaped to exhibit a plurality of recesses therealong, the plurality of recesses being spaced to receive a plurality of different flange bolting patterns for the same size conduit, wherein the flange adapter is configured to align the central axis of the cylindrical bore of the pressure containing member coaxially with a central axis of the fluid flowpath of one or more of the inlet flange member and the outlet flange member; and wherein the flange adapter is configured to align the insert device relative to the central axis of the fluid flowpath of one or more of the inlet flange member and the outlet flange member.
