Hydrocarbon resource recovery system and component with pressure housing and related methods

A hydrocarbon resource recovery component in a hydrocarbon resource recovery system for a subterranean formation comprising a radio frequency (RF) antenna within the subterranean formation for hydrocarbon resource recovery, an RF source aboveground, and a dielectric fluid pressure source, the hydrocarbon resource recovery component comprising:

• a coaxial RF transmission line coupled between the RF antenna and the RF source and having an aboveground portion;
• and
• a plurality of pressure members joined together in end-to-end relation to define a pressure housing coupled to said dielectric fluid pressure source and surrounding the aboveground portion of said coaxial RF transmission line;
• said plurality of pressure members comprising at least one straight tubular pressure member, and at least one elbow pressure member coupled thereto and comprising upper and lower longitudinal halves having respective opposing flanges joined together.

A method for assembling a hydrocarbon resource recovery system for a subterranean formation comprising:

• positioning a radio frequency (RF) antenna within the subterranean formation for hydrocarbon resource recovery;
• positioning an RF source aboveground;
• coupling a coaxial RF transmission line between the RF antenna and the RF source and having an aboveground portion;
• and
• coupling a plurality of pressure members joined together in end-to-end relation to define a pressure housing coupled to a dielectric fluid pressure source and surrounding the aboveground portion of the coaxial RF transmission line;
• the plurality of pressure members comprising at least one straight tubular pressure member, and at least one elbow pressure member coupled thereto and comprising upper and lower longitudinal halves having respective opposing flanges joined together.
