The WELLCARE Flow Coupling/Blast Joint is a thick-walled section of tubing that minimizes the resultant effect of internal erosion that occurs in a tubing string from changes in the internal cross-section of a flowing well.
These are used to protect the tubing string from the abrasive action of flowing gas or oil when positioned opposite the perforations. It may also be used directly below the well head to protect from the abrasion of doing a hydraulic fracturing operation down the annulus.
Full tubing ID is maintained through the Blast Joint with the OD the same as tubing couplings. As standard it is available in API tubing connections.
Ceramic or Carbide Blast Joints are available on request.
