FCE Swivel Joints

Swivel Joints

Swivel joints have been used in the oilfield services for almost a century. Swivel joints have built a worldwide reputation with generation to generation of field operators.
The applied technologies of  swivel joints have proven their high level of efficiency in extremely severe flow conditions such as very high pressure & flowrates, high & low temperatures, multiphase flow, erosive and corrosive agents, vibration in pumping piping systems, etc…

FCE is one of the most reputed manufacturers of Wing unions & swivel joints approved by the major worldwide service companies. FCE products for oilfield services focus on Sour Gas service and most severe applications.

How to select your swivel joint

In order to provide the fitting for a given application, it is essential to specify the following information :

1 – Flow conditions:

  • Max operating pressure.
  • Min and Max operating temperature (fluid).
  • Max flow rate.

2 – Fluid characteristics:

  • abrasive & corrosive content

3 – Mechanical constraints :

  • Radial & axial loads.
  • Rotating speed.

4 – Service and environmental conditions:

  • Ambient temperature & environment (indoor, outdoor).
  • Service frequency (time per day).
  • Piping system configuration & line size.
  • Swivel style





Swivels are sold loose (buttweld or threaded) or fully assembled with end connections to be specified (flange,wing union, etc.). FCE also manufactures cementing and circulating hoses up to 6000 PSI.
