Installing a snap-lok Plug
Step 1

Identify the damaged panel. snaP-lok
plugs can be fitted into any location
within the frame except those openings
adjacent to the shaker side walls.

Step 2

Turn the screen
over and lay
the screen on a
flat surface (a
bench or the
floor, for example)
in an area free
of obstructions.
Place the plug

above the damaged panel with the
hollow section facing up.

Step 3

Push the plug in
as far as it goes.

Step 4

Place a second
plug on top of the
first plug with the
hollow section
facing down.

Step 5

Push down on
both plugs with
your hand until the
first plug clicks
into place. If the
plug does not click

into place, use a hammer or a mallet
to tap the second plug. Hold the second
plug in place with a finger to prevent it
from jumping back. Make sure both ends
of the plug are struck firmly.

Step 6

When the plug is
fitted correctly,
the second plug
will sit flush with
the rest of the
frame. Remove the
second plug from
the frame. Once
the first plug is in
place, it cannot be
removed.

Solids Control, Pressure Control & Waste Management – Version 5

For NOV Brandt Cobra shakers
The Duraflo* Composite Replace ment
Screens from M-I SWACO, for the
National Oilwell Varco (NOV) Brandt
Cobra^, King Cobra^ and LCM-3D^
shakers, provide greatly improved
performance and reliability over
traditional metal-backed screens.

M-I SWACO Duraflo Composite
Screens use a polypropylene frame
with an internal reinforcing cage made
of high-strength steel. This new design
improves solids-control performance
by increasing screen life and fluids-
handling capacity while providing a
screen that is lighter in weight than
older, metal-backed designs. For
adaptability to a wide range of drilling
conditions, Duraflo Composite Screens
are available with XL Mesh, a triple-
layer square opening cloth, and with
patented XR MesH for increased screen
life and capacity.

Because the mesh is bonded directly
to the composite frame in the Duraflo
design, there is no need for a separate
support plate that could detach from
the frame during operation. An integral
gasket on the bottom of each frame
provides an excellent seal between the
screen and the shaker, and the virtually
unyielding bond between the frame

and soft gasket allows the screen
to be removed and reinstalled while
still supplying a reliable seal. These
improvements add up to improved
screen life and savings on per-well
screen costs.

The patented Duraflo design has been
developed over several years and has
proven effective in increasing fluids-
handling capacity on other equipment,
such as the M-I SWACO Mongoose
Pt and BEM-650 shakers and Brandt
VSM 300 shakers. This improved
capacity is a result of increasing
the non-blanked area of the screen. For
the Duraflo screen, non-blanked area
has been increased 20%, allowing finer
screens to be run and improving solids-
removal efficiency.

Lower weight is another advantage of
Duraflo screens vs. metal-backed.
By bonding the mesh directly to the
composite frame and eliminating the
steel support plate, screen weight has
been reduced by 29%. This reduction
makes installation easier and safer.
And, because the frame is specifically
designed to match the overall screen
frame with the overall shaker support
structure, the rigid frame efficiently
transfers vibration from the shakers to
the screen mesh.

On traditional metal-backed screens,
the mesh is bonded to a metal plate,
which is in turn bonded to a steel frame.
A gasket is then glued onto the bottom
of the frame. The result is a screen
made of multiple components that can
fail at any of the bond lines.

On the M-I SWACO new Duraflo
Composite Screen, the mesh is bonded
directly to the molded structure and has
little opportunity for catastrophic
failure. The absence of adhesives from
the screen also removes the chance of
chemical attack on glued components.
The gasket remains in place even
when drilling with hot, oil-base muds,
whereas the gaskets on metal-framed
screens have a history of separating in
this application.
