Product Description

API Sub Surface Release Top and Bottom Cementing Plugs

Product introduction:
A rubber cementing plug used to separate the cement slurry from other fluids, reducing contamination and maintaining predictable slurry performance. Two types of cementing plugs are typically used on a cementing operation. The bottom plug is launched ahead of the cement slurry to minimize contamination by fluids inside the casing prior to cementing. A diaphragm in the plug body ruptures to allow the cement slurry to pass through after the plug reaches the landing collar. The top plug has a solid body that provides positive indication of contact with the landing collar and bottom plug through an increase in pump pressure.
 
product Features:
Cementing plugs are manufactured of graded rubber that is fused upon a composite or  Aluminum core. 
These plugs are completely PDC drillable. 
Operating range 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 in 4 1/2" to 20 "sizes + any special sizes.
