Cementing Plug, Conventional / Non-rotating / Self-locking // Material Fin Matl: NBR/HNBR; Core Matl: Aluminium/Plastic Pressure Bump: 5000 psi Temperature 204°C Type Conventional Top Burst Pressure Range 200-400 psi

CRIMSON Conventional Top & Bottom Cementing plugs are manufactured of graded rubber that is fused upon a composite or Aluminum core.

These plugs are completely PDC drillable.

CRIMSON has designed its plastic core and aluminium core cementing plug to compliment its line of plugs to decrease drill out times.

The cementing plug is used for separating the cement slurry from the mud.

It can prevent the mud from blending into the cement slurry to influence the cementing quality.

Structure features:

• The top plug is solid; the bottom plug is hollow. They can all be drilled out with PDC bits.

• The material of the plug body is acrylonitrile-butadiene rubber. It is heat-resisting and tough.

• The core is made of a glass-filled high strength phenolic resin core.

• The tapered base fits the cavity of the bottom plug for a positive seal. The fins and tail section provide positive wiping action. Fins also serve as a seal while cementing.

• A rubber diaphragm at the top of the plug ruptures after the plug is seated allowing cement to flow through.

• The Cementing rubber plugs are available in sizes 4 1/2″ to 20″.

CRIMSON Non-Rotating Top & Bottom Cementing Plugs are designed to decrease drill out time.

When the drilling fluid make the bottom plug move into the end, raised tread type petal of the bottom plug’s lower end engaging with the hollow thread type petal of float collar’s upper end. At the same time, the pressure rise, when reach the definite pressure, the burst disk in the bottom plug crush, the passageway open, and the pump pressure descent, at this time can cementing.

After cementing, pumping into the top plug to clean cement slurry on the inner wall, the raised thread type petal of the top plug engaging with the hollow thread type petal of the bottom plug. B

affle plates can also be ordered for threaded casing collars is available in casing sizes 4 1⁄2″ through 13 3⁄8″ and tubing sizes 2 3⁄8″ through 4 1⁄2″.
