VAM® HTF-NR™

VAM® HTF-NRTM (High Torque Flush) is a flush OD integral connection providing maximum clearance along with extreme torque strength for challenging applications such as drilling with casing, liner rotation to achieve better cementation in highly deviated and critical High Pressure/High Temperature wells. 

The VAM® HTF-NRTM is an optimized design of VAM® HTFTM and became the new standard version of VAM® extreme high torque flush connection. The VAM® HTF-NRTM has extensive tests as per API RP 5C5:2017 CAL II which include the gas sealability having load points with bending, internal pressure and high temperature at 135° C.

 Applicable range

  • ​Available in sizes from 4 1/2" to 9 7/8". Others sizes are available upon request
  • Standard and alternative drifts as per API 5CT and special drifts upon request
  • ​Validated on Carbon, Martensitic stainless steel, for Yield Strengths from 80 ksi to 140 ksi​.

 

 Applications

  • Production liners
  • Drilling liners and liners to be rotated into place during cementing
  • Horizontal / deviated wells
  • Extended Reach​ and slim hole wells​. 
  • Drilling with liner / casing

     

 

 Performances

  • An external and internal metal-to-metal seal work independently of each other to achieve 100% sealability against annular and well bore pressures
  • Extensive tests as per API RP 5C5:2017 CAL-II

 

 Benefits

  • Proven gas sealability
  • Maximum clearance
  • Superior rotational capability
  • User friendly
  • Reliable internal and external pressure integrity, and under combined loads.
