IRI's Top Rubber Plug |
Industrial Rubber
offers three types of Rubber Plugs, the Top Rubber Plug, Bottom Rubber Plug and the Omega
(Ball-Type) Plug.
Industrial Rubber Cementing Plugs are engineered for reliability. The
Top Rubber plug and Bottom Rubber Plug are of the same basic design with firm wiping
action provided by five wiping surfaces.
The Cup design on top and bottom of both plugs provides a sure seal
against the casing wall to prevent mixing of cement slurry and displacement fluid. The Top
Plug seats and seals into the Bottom Plug to lessen the possibility of additional cement
slurry displacement and assure good bonding at the bottom of the casing.
The Top Rubber plug has a core of epoxy coated sand
compressed into a solid mass allowing the plug to withstand shock when pumped to touchdown
and allows unbelievable drill ability. The core is completely encased in rubber and has a
solid base to prevent separation.
Bottom Rubber Plug has a core of cast aluminum
(PDC DRILLABLE). After the plug has completed its cleaning of the casing ahead of
the cement slurry and seated at touch down, additional pressure ruptures the rubber
diaphragm at the top of the core allowing slurry to continue to its’ destination. Additional Strength
is engineered into Industrial Rubber's Top Rubber Plug. Note solid base eliminating the
possibility of plug collapse caused by a core being pumped out.

Omega
Rubber Plug
OMEGA CEMENTING PLUGS are designed using solid rubber with
the top portion larger than an ordinary top plug. As the plug travels down the casing it
elongates and applies more pressure against the casing wall assuring a better wiping
effect and greater separation of cement slurry and displacement fluid. Available only in
tubing sizes. |

Top
Rubber Plugs have a special non-metallic core destined for easy drill-out. It is
completely encased in rubber to prevent separation during pump-out. |
Bottom
Rubber Plugs are designed with a special aluminum alloy cylinder and is PDC Drillable. The
use of plastic or other polymers for this purpose can result in plug failure. Another
reason for using Aluminum, some bottom hole temperatures exceed the limits of Plastic
polymers. |
