Wholesale API High-Quality Cementing Top/Bottom Plugs for Oilfield Applications
Cementing Plug
We excel in offering API oilfield drilling cementing tools, particularly cement plugs designed for both top and bottom applications. These plugs play a crucial role in the cementing process by effectively separating cement slurry from other fluids. This ensures reliable slurry performance and prevents any contamination. We provide two commonly used types of cement plugs that are widely utilized in cementing operations.
Cementing Plugs:
Cementing plugs are manufactured of graded rubber that is fused upon a composite or Aluminum core.
>>This top plug can be used when dual plug system is not required and Bottom cementing plug can be used when dual plug system is required.
>>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.
Top Plugs:
The Bottom 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 bottom plug initiating a positive seal. A solid rubber top plug is also available.
Bottom Plugs:
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 such as Plastic, Aluminium or Phenolic depending on the application and well conditions. A rubber diaphragm at the top of the plug ruptures after the plug is seated allowing cement to flow through.
