Methods of manufacturing a pre machined forging and finish of a hydrocarbon well submarine, submarine and pre machined forging system

摘要

This is a manufacturing method of a forge pre machined configurable for use with a tubing hanger of multiple holes or a tubing hanger hole includes providing a single blockValve with a common master configurable main hole (46) along a geometric axis central main (AX).After providing the block valves master common configurable.A set of sub target is identified that has a End Sub bore only one with a production borehole along a geometric axis center of a tubing hanger.Or a End Sub multiple holes with the production borehole displaced axis geometric central tubing hanger.If the set of submarine target has the end sub hole only,The machining of a lower interface (62) of the block valves common master is centralized around the central main geometric axis (AX).If the set of submarine target has the end sub multiple holes.The machining has a geometric axis interface eccentric (64) which is parallel to the geometric axis central main (AX) and moved in the same.
