VAM® HTTTM (High Torque Tubing) is a premium connection threaded on pipe with internal and external upset ends offering excellent performance combining gas tightness/compression and exceptional high torque resistance.​


  • Available in sizes from 2 7/8" to 5 1/2".​


  • Multiple purpose utility tool (tubing, work string, drilling string, test string)
  • Best in class on torque + gas tightness
  • ​Easy to implement on the field (stabbing / running)
  • ​​User friendly.​​


  • Tubing used as drilling string in a technique known as Drilling with Tubing (DWT). High compression and torsion loads are required.
  • Drill Steam Test (DST) on exploration wells requiring multiple trips downhole acting as temporary tubing while testing potential production zones.
  • Tubing acting as casing and being cemented with rotation (eventually) in a technique known as tubing less.
  • Tubing acting as work string on work-over operations.​


  • Multiple makes & breaks without galling. In all applications make-up in stands (2 or 3 pipe) if required.
  • Metal-to-metal seal 100% internal pressure / external pressure, 100% tension; 60% compression +EP
  • High torsion resistance. Torsional performance with sealability
  • Tested under ISO 13679 CAL-III
  • Excellent fatigue performance
  • Excellent gas tightness​.
