ОМК VEGA
Premium gas-tight full-strength thread and coupled connection
The connection is designed with a special thread hooked profile witha negative angle, a metal-to-metal seal, and full strength that assures that the connection remains gas-tight under a compressive load equal to 100% of pipe body strength.

Potential Applications
- Oil, gas, and offshore fields
- Vertical, extended reach drilling and horizontal wells
- Construction of long offshore and onshore ERD wells with type -S and -L profiles
- Wells with aggressive H2S and CO2 environments
- Production of heavy crude oil using SAGD
- Casing running and cementing technologies with rotation in a long horizontal wellbore
- Multistage frac operations in long horizontal casing strings
Factors of Improved Reliability
- Special thread hooked profile with a negative angle protects the connection from dissemble when running the strings
- An increased TPI allows for better thread assembly on a rig under field conditions
- The thread connection is of equal strength with a pipe body. Efficiency connection in compresion equals to 100% of the pipe body
- The gas-tight metal-to-metal seal assembly guarantees leak-proofness at high bending and compression loads
- Additional internal shoulder providing resistance to high torques
- An increased connection ID allows for more flexibility in selection of downhole equipment
- Inspection of thread connection assembly based on specified make-up torques and an assembly diagram
- CLEAN SPACE dope-free technology option
- OMK VEGA design has been verified by successful bench testing per API 5C5:2017 CAL IV level
