Nitrile rubber Top Cementing Plug
Top Plugs:
The Top cementing plug is designed to exert continuous pressure on the casing wall. The core is made of aluminum or phenolic depending on the application and well conditions. The tapered base fits the cavity of the bottom plug initiaing a positive seal. A solid rubber top plug is available.
Bottom Plugs:
Like the Top Cementing Plug, the fins and tail section provide positive wiping action. Fins also serves as a seal while cementing. The core of bottom plug is also made of special material such as aluminium or phenolic resins depending on the application and well conditions. A rubber diaphragm at the top of bottom plugs ruptures after the plug is seated allowing cement to flow through.
Features:
Bore diameter meets professional standard and has no influence on pump pressure
Drillable aluminum alloy is adapted in internal firmware which mechanical capacity is much better than plastic or glass fiber reinforced plastic
Reduces drilling time and provides cement plug enough braced force while cement plug is descending in casing.

Description :
The Cementing Plugs manufactured in our company include top plugs and bottom plugs. These plugs offer the following advantages:
Features:
♦ Spceial non-rotational device design allowing the plugs to drill out quickly;
♦ Special materials designed for easy drill out with PDV bits;
♦ High temperature and high pressure resistance.
API Downhole Cementing Accessories Top and Bottom Cement Plug with factory price
1) Types Available: Conventional standard plugs and non-rotating plugs are available;
2) Standard: API
3) API and ISO certified
4) Specifications: 4 1/2''---20''. More special sizes or combination are available as requested.
5) Material: Rubbers and Phenolic Resins.
Usage
The cementing plug is used to separate the cement slurry from the mud. It can prevent the mud from blending into the cement slurry to influence the cementing quality.
Structure characteristics
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.
