Product Description:

Anti-rotation rubber plug is designed with anti-rotation mechanism, which can greatly improve the drilling speed.

Innovative design includes plugs that have locking teeth on both the top and bottom plug and super seal float collars that allow plugs and casing equipment to lock together during drill-out.
 

Non rotating cementing plugs also are equipped with high strength drillable plug inserts designed to withstand casing test pressures after the job is completed.
 

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.

 

The top cementing plug is designed to exert continuous pressure on the casing wall. The core is made of special materials such as Plastic, Aluminium or Phenolic depending on the application and well conditions. The tapered base fits the cavity of the top plug initiating a positive seal. A solid rubber top plug is also available.

The bottom plug is like the top cementing plug. The fins and tail section provide positive wiping action. Fins also serve as a seal while cementing. The core of the bottom plug also made of special materials.A rubber diaphragm at the top of the plug ruptures after the plug is seated allowing cement to flow through.

The top plug and bottom plug are designed with double-stage sealing and scraping wings.
 

Scraping wings processed by wear resistant materials.
 

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 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.

 

There are two kinds of cementing plug: Conventional cementing plug and special cementing plug. Conventional cementing plug is divided into Top plug and Bottom plug.

Special plug has Top/Middle/Bottom plug used in two-stage cementing, drill pipe plug and hollow plug used in drilling liner cementing and composite plug used in composite casing.
