Connection List
The connection list gives you access to the VAM® and NSMAXᵀᴹ product lines. Because not all products can be listed, such as fit-for-purpose or so-called isolated products, please contact Nippon Steel engineer in case the VAM® or NSMAXᵀᴹ connection you are looking for is not listed.
VAM® SLIJ-II is an improved, second generation version of the former VAM® SLIJ connection. It is an integral casing joint machined on plain-end non-upset pipe. The design combines a near-flush OD with high tensile efficiencies and stronger structural integrity. The connection is ideal for production and intermediate casing, liner and tie-back applications in all types of wells.

Applicable range
- VAM SLIJ-II is available from 4 1/2"" to 16"
- API weights and heavy weights up to 0.900" wall thickness
- Standard, Alternative and Special Drifts
- Carbon steel and Corrosion Resistant Alloy material
- Yield strengths from 80 ksi to 125 ksi
Generous running clearances
- Box is expanded and turned down to ODs that are typically 2% to 3% over the diameter of the pipe.
High tension and compression strength
- Thread design incorporates broad critical sections that develop tension efficiencies of 70% to 80% of the pipe body yield strength.
- Thread form and 90° Middle torque shoulder contribute to high compression strength, equal to 70% of the joint strength in tension.
Great structural integrity
- The new compound tapered cylindrical thread form design utilizes four planes to optimize stresses throughout the connection.
- The negative 10° hooked thread profile securely locks connection and prevents jump-out under high tension, even in the most severe conditions of over-doping.
100% Pipe Body burst and collapse
- A unique combination of internal and external metal-to-metal seals prevent pressures from entering the connection, ensuring connection pressure ratings greater than or equal to the pipe body ratings.
DEA-27 tested
- VAM® SLIJ passed the severe DEA 27 6 samples test procedure for flush and semi flush connectors.
User friendly
- VAM® SLIJ-II was specially developed to withstand severe excess of thread compound (over-doping).
- The connection stabs deep, with no risk of cross threading. Make-up is easy and controlled by the 90° Stop shoulder.
