Offset flange and angled shim flowline fittings

A directional flowline fitting, said fitting being adapted for assembly into a flowline segment providing a single conduit in a fluid transportation system to provide a change of direction in said single-conduit segment;

• said fitting comprising:
• (a) a prismatic body having a single conduit therein consisting of first and second intersecting straight line bores, said first bore providing an inlet and said second bore providing an outlet;
• (b) said bores extending from, respectively, a first union face and a second union face on said body, said union faces being adapted for connection to a flowline component by a flange union;
• (c) wherein the extended planes of said first and second union faces intersect at an interior angle θ less than approximately 90°.

A flowline segment providing a single conduit in a high-pressure fluid transportation system, said single-conduit segment having a change in direction and comprising:

• (a) an offset component assembled into said segment by flange unions, said offset component comprising:
• i) a body defining a substantially cylindrical central conduit, said conduit extending between first and second union faces and adapted to conduct fluids through said body;
• ii) said union faces having a plurality of holes accommodating threaded connectors for said flange unions;
• and
• iii) said holes being arranged in a defined array extending angularly around said conduit;
• iv) wherein said array of holes on said first union face and said array of holes on said second union face are offset angularly relative to each other by an angle Δ;
• and
• (b) a directional fitting assembled into said segment by flange unions, said directional fitting comprising:
• i) a prismatic body having a single conduit therein consisting of first and second intersecting straight line bores;
• and
• ii) said bores extending perpendicularly from a first union face and a second union face on said body;
• iii) wherein the extended planes of said first and second union faces intersect at an interior angle θ less than approximately 90°.
