| VAM TOP® is a T&C connection ideal for tubing
and production casing strings applications. VAM TOP® provides
gas-tight sealing under the most severe conditions
including great depths, highly deviated holes, and
hostile environments. It outperforms the majority of
today's premium connections designed according to casing
and tubing requirements. BENEFITS
- Excellent gas-tight sealing
under combined loads
- Excellent resistance to
bending, compression and
torque
- Excellent resistance to external
pressure and compression
- Easy to use and repair
New Metal-to-Metal Seal
- A patented
metal-to-metal seal system offers from 2 3/8" to 14" excellent
gas tight sealing even under the most severe
combined loads,
as encountered
in deviated or long horizontal wells applications.
- Sealing integrity remains constant despite repeated
make-up and break-out.
- Seal geometry protects against galling.
Reverse Angle Torque Shoulder
- A reverse angle torque
shoulder provides a positive torque stop which
allows for accurate power tight
make-up and minimizes hoop stresses in the connection.
- The wedge effect caused by the reverse angle
gives the connection superior structural strength.
- The shoulder design is optimized in order to
resist adverse conditions such as combined
compression and
external pressure or combined bending, compression
and torque (See the corresponding gas tight
VME Performance Envelopes for tubing and casing
sizes).
Improved Hook Thread Design
- A modified hook thread
profile, with 3° reverse
angle on the load flank, not only provides the
connection with superior tension strength but also
increases
its resistance to compression.
- The excellent structural strength including
increased bending and compression resistance, makes
this
connection especially suited for highly deviated
and long horizontal
wells.
- Optimized thread geometry minimizes the risk
of galling even when thread lubricants are
poorly applied.
Coupling Design
- Coverage of the vanishing threads, long internal
shoulder, and coupling critical cross sections
greater than those of the pipe body, contribute
to a high
performance, 100% efficient connection.
Streamlined Internal profile
- A pin ID chamfer, tight tolerances on the coupling
center and a long shoulder combine to minimize
turbulence and energy loss inside the connection
for high velocity
gas flows.
Options
- VAM TOP SC90 / VAM TOP SC80 (Special clearance):
these extra-clearance couplings offer 90% and 80%
tensile efficiency respectively.
