  • B-1 - Flange with tubing thread prep bottom x tubing thread top
  • B-2 - Flange with tubing thread prep bottom x studded top

  • BO-10 - Flange with coupling bore bottom (coupling retained with lock ring) x studded top

Control Line


Control lines play an important role in well completion design. As wells become deeper and well environments more hostile and aggressive, higher pressure rated, larger diameter control lines manufactured from higher strength, more corrosion resistant materials are becoming more prevalent in oilfield applications. This has lead to FMC Energy Systems developing innovative designs to allow control lines to be an integral part of the wellhead system.
