Abstract

The present invention relates to hydrocarbon well fluid manifold module ( 1 ) with a manifold module housing ( 9 ) having a transversal bore terminating in a longitudinal bore ( 3 ) in fluid connection with the transversal bore ( 6 ). One or more cut off valves are located ( 7 ) in the transversal bore ( 6 ). The longitudinal bore ( 3 ) extend through the module housing ( 9 ) and form a first flow port ( 11 ) and a second flow port ( 12 ) aligned with the first flow port ( 11 ). Plane, connecting surfaces surround the two flow ports ( 11,12 ). The two flow ports and connecting surfaces are identical. The first connecting surface ( 13 ) and the second connecting surface ( 14 ) are adapted to be connected to at least one further similar manifold module ( 20 ). The invention also concerns a manifold for a hydrocarbon well assembled of such modules.

First claim

1 . A hydrocarbon well fluid manifold module ( 1 ) comprising a manifold module housing ( 9 ) having a transversal bore terminating in a longitudinal bore ( 3 ) in fluid connection with the transversal bore ( 6 );

2 . The hydrocarbon well fluid manifold module ( 1 ) of claim 1 , wherein the housing ( 9 ) is formed as one unitary metal block, whereby the longitudinal bore ( 3 ) and the transversal bore ( 6 ) terminating in the longitudinal bore form a T-shaped bore inside the unitary metal block.

3 . The hydrocarbon well fluid manifold module ( 1 ) of claim 1 further including connection bolt bores ( 4 ) surrounding the longitudinal bore ( 3 ).

4 . The hydrocarbon well fluid manifold module of claim 1 including two cut off valves ( 7 ) in the transversal bore ( 6 ) providing a redundant cut off valve.

5 . The hydrocarbon well fluid manifold module ( 1 ) of claim 1 wherein the longitudinal bore is uniform and has an internal diameter in the range from 8-16″ (203 mm-406 mm) and the transversal bore has an internal diameter in the range from 5-8″ (127 mm-203 mm).

6 . A hydrocarbon well fluid manifold assembled of a plurality of hydrocarbon well fluid manifold modules ( 1 ), including at least a first and a second well manifold module, each comprising a manifold module housing ( 9 ) having a transversal bore ( 6 ) terminating in a longitudinal bore ( 3 ) perpendicular to and in fluid connection with the transversal bore ( 6 );
