| VAM SLIJ-II
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.
BENEFITS
- Generous running clearances
- High tension & compression
strength
- 100% Pipe Body burst and collapse
- User friendly
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.
