Expansion Joint


The Expansion Joint is used below the running tool when running slotted or screen liners. Run toward the top of the inner string, this tool allows ease of spacing out. The inner string is first run to the liner circulating shoe. A space out calculation is then performed to determine length needed for simultaneous make up of inner string and liner. The expansion joint accommodates length deviation from this calculated value, eliminating the need for additional pup joints.


  • 5 ft sliding adjustment to allow for deviations in the inner string space-out
  • Positive seals in all space-out positions
  • Differential pressure rating of 5,000 psi
  • Available with various tubing thread connections to match inner string connections
