ALCOA FLUSH JOINT ALUMINUM DRILL PIPE
Flush Joint Drill Pipe Designed for Mobile Drilling Rigs
Drill farther, faster.
Extend your rig’s drilling capacity - 30% to 50% or more -
using the same portable rigs typically used to drill 500 – 4,000
feet. Alcoa Flush Joint Aluminum Drill Pipe makes it possible
because of its inherent strength-to-weight ratio: Alcoa Aluminum
Drill Pipe delivers the load capacity of steel with approximately
half the weight. Alcoa Flush Joint Aluminum Drill Pipe is available
in Range 1 and Range 2 lengths or custom lengths to suit
customer specifications.
Increase rig capacity.
Save on transportation costs.
Designed for use with all standard mobile
rigs, whether top head or rotary table drive,
Alcoa Flush Joint Aluminum Drill Pipe can
increase your rig capacity by as much as
30% in air drilling, and significantly
more in mud drilling. In addition,
it reduces transportation costs,
because a truck can handle up
to 60% more aluminum pipe
than steel. In fact, a 2,500 ft.
string of 4-1/2” flush joint
aluminum drill pipe can
be delivered to the drill
site on one trailer.
Extend drilling capacity.
Drilling with Alcoa Flush Joint Aluminum Drill Pipe can reduce
rotating torque, providing for extended drilling capacity.
In addition, it exhibits less string drag during pull-out than steel
pipe, as well as greater buoyancy when drilling in fluids.
Alcoa Flush Joint Aluminum Drill Pipe’s lighter
weight also offers:
• Energy savings – a portable rig will
use from 15% to 20% less fuel to
hoist aluminum pipe vs. steel.
• Durable - extra thick wall allows drill
pipe to withstand nearly twice as
much wear before downgrading.
• Ease of connections – aluminum pipe
is easier to stab on connections,
adding to the efficiency of drilling
operations.
