Selection tool:
VAM® HTF (High Torque Flush) is a true flush OD and ID integral connection providing maximum clearance along with superior 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.
VAM® HTF innovative design combines two metal to metal seals with threads that are optimized to provide maximum torque. VAM® HTF is the unique extreme torque connection qualified to ISO 13679 CAL-IV for tension, compression, bending, thermal cycling and gas sealability.
Benefits
|
Applicable range
- VAM HTF is currently available from 4 1/2" to 9 5/8", other sizes available upon request
- API weights
- Standard, Alternative and Special Drifts
- Carbon steel and Corrosion Resistant Alloy material
- Yield strengths from 80 ksi to 140 ksi
Integral flush design for maximum clearance
- VAM® HTF is an integral connection threaded on plain-end pipe where the OD of the connection totally flush with the pipe body.
Maximum torque strength
- The high torque strength of VAM® HTF permits pipe rotation in deviated holes without fear of structural failure.
- VAM® HTF specific and patented thread profile has been designed with a progressive lead and a dove-tail profile. When making-up the connection, this “self-blocking” feature will provide the end-user with a huge torque resistance.
- VAM® HTF features 2 threaded sections located on the same axis allowing deep and easy stabbing for better running performances.
Multiple metal-to-metal seal system
- An external and internal metal-to-metal seal work independently to achieve 100% sealability against annular and well bore pressures.
- The gas-tight sealing integrity has been tested and proven under the most severe qualification procedure ISO13679 CAL-IV.
Streamlined internal and external profile
- The connection OD and ID are 100% flush to the pipe body.
- The ID is bored.
- The OD is turned to flush OD dimension for maximum clearance.
- Repairable by VAM® licensed workshops with minor pin-end swaging and box-end expansion prior to threading.
