| DINO VAM joint is a cost effective
T&C connection
for surface and intermediate casing applications. DINO
VAM connection was specifically designed to reduce
rig operating costs by providing running reliability
through deep stabbing, no cross-threading and quick
make-up. This connection provides sealing with coarse
3 TPI tapered hooked threads. It is immune to jump-in
/ jump-out. BENEFITS
- Reduced running time by 30% compared
with API Buttress
- Field efficiency with deep stabbing
and no cross-threading
- Internally flush
- No jump-in or jump-out
- Better sealing than API
Buttress with metal free dopes due to thread
sealing
Unique Torque Control
- A make-up arrestor positions
the coupling accurately on the mill end.
- Pin to pin torque shoulder for
positive torque stop on the field end allows overtorque
and compression
resistance.
Improved
Thread Design
- Modified hook thread profile,
with -9° reverse
angle on the load flank and +20° on the stabbing
flank which provides superior load carrying performances.
- Increased thread taper, combined with a wider
thread profile allows deep and efficient stabbing
with
no
cross threading.
- Increased thread pitch to reduce make-up time.
- Jump-out free.
- Special thread design to offer superior thread
sealing performances.
Coupling Design
- Vanishing threads,
fully covered.
- 100 % tensile efficiency for all
sizes standard
API Buttress OD.
Streamlined Internal Profile
- Pins shoulder, thereby
providing a smooth bore ID to minimize turbulence
and energy losses.
- Pins shoulder, thereby providing high compression
resistance and immunity to jump-in.
Advanced Operational Capabilities
- Reduced Operational Costs
- High stabbing efficiency
tolerant to misalignment and suppressing cross-threading.
- Make-up torque tolerance ± 15
%.
- No galling after repeated make-ups
and break-outs.
- Half the turns of API Buttress required
for make-up
The advanced design of the DINO VAM joint was thoroughly
tested on a rig and the benefits verified.
