CEMENTING PLUGS
NON-ROTATIONAL CEMENTING PLUG, CEMENTING TOOLS, CASING BUOYANCY
SYSTEM PART, TOP OR BOTTOM , ANTI ROTATION
Cementing plugs are used to remove the mud during cementing
operations.
Top cementing plugs and bottom cementing plugs are used in the
cementing process. The top and bottom
cementing plus general have different colors (bottom plugs are red
and top plugs are black) in
production for easy usage in operation.
The top cementing plug has a solid body that provides positive
indication of contact with
cementing floating collar and bottom plug through an increase in
pump pressure.
The bottom cementing plug with a hollow body is installed ahead of
the cement slurry to
minimize contamination by fluids inside the casing prior to
cementing.
ADVANTAGES AND MAIN FEATURES
Non-rotating cementing plugs are designed to decrease the drill out
times. Reinforced locking teeth are
built into the plugs, which lock together between the plug and the
float equipment to eliminate rotation
of the plug during drill out. The top cementing plug are latched to
the anti-rotational float collar.
