Non Rotating Type Cementing Plug
Application
Our cementing plugs are specially designed with a positive wiping action to ensure that the casing is clean.
The top cementing plugs is designed to exert continous pressure on the casing wall.
The fins and tail section of bottom plugs provide positive wiping action. Fins also serve as a seal while cementing.
Structure:
The core is made of aluminum or phenolic resins, depending on the application and well conditions.
The plug is made of high performance materials such as rubbers or phenolic resins.
Using Method:
Place bottom plug before injecting cement, and pump the scrape to clean the well-wall. After all is set, build the pressure of 2-4MPa till the rubber diaphragm is broken, and thus circulation is formed. Then inject the cement, place the top plug, pump, set the pressure, and well cementation comes to an end.

Cementing plug have been designed to decrease drill out time.
These series of cementing plug have reinforced locking teeth built into the plugs, which lock together between the plugs and the float equipment to eliminate rotation of the plug during drill out.
These plugs are made of Graded Rubber with Aluminum or Phenolic core inside, No other metal parts are used .
These plugs are completely PDC drillable.
Operating rage of temperature with Aluminum core is up to 200 degree Fahrenheit.
Plug can be ordered for higher operating temperature and operation in either synthetic or mud fluids.
Available sizes from 4-1/2" to 20".
