Major
Benefit |
Best
for tubing and production casing, new generation
replacing VAM ACE and NEW VAM |
Designed
for the various high-compression applications
(Elevated temperature, compaction) |
Designed
for the various high-torque applications (Rotating
liner and casing while running or cementing ) |
Near
Flush OD. Best
compromise between clearance and strength. |
Flush
connection for max clearance. |
Specially
designed for heavy wall pipes (0.600 to 1.400
wall). |
Very
successful for CRA materials. Predecessor
to VAM TOP. |
Has
been the most popular premium joint in the world
for years. |
Cost
effective connection, faster, easier to run and
higher performance than Buttress |
Large OD connection for quick
running |
VAM
TOP connection with special fatigue enhancement

*Compression and bending ratings
are conservative and are calculated to retain
gas sealability in all domains of the performance
envelope. Structural compression and bending
ratings are higher. |
