where to buy Top and Bottom Rubber Cementing Plugs

Rubber cementing plugs are used for wiping drilling fluids of casing ID by five wiping surfaces,are used to separate the cement slurry from fluids.The top rubber plug and bottom rubber plug are available and are of the same basic design. These are designed to match the industry standard,to match the cementing heads and float equipment.

We are desinge, manufacture,supplier and exporter for full lines of standard cementing wiper plugs and non rotating casing cementing plugs, these two kinds of cement plugs include top plugs and bottom plugs. In order to meet the increasingly conditions of deeper and higher pressure drilling, different material rubber cementing plugs are designed.

Our Cementing Plugs features

Plug sizes from 4-1/2inch to 20inch.
Available with top rubber cement plugs and bottom rubber cement plugs.
Available with standard cementing plugs and non rotating cementing plugs.
Easy drill-out with PDC and insert bits.

There are 2 kinds of cementing plugs.top plugs and bottom plugs

The Top Rubber plughas a core of epoxy coated sand compressed into a solid mass, which allows the plug to withstand shock when pumped to touchdown, while also retaining its ability to be drilled out. The core is completely encased in rubber and has a solid base to prevent separation.
The Bottom Rubber Plug has a core of cast aluminum that is PDC drillable. After the plug has completed its wiping of the casing ahead of the cement slurry and seated at touchdown, additional pump pressure will rupture the rubber diaphragm at the top of the core, allowing slurry to continue to its destination.

The working of cementing plugs

  • Plugs plays a vital role during cementing operations. Plugs minimize the contamination of cement by removing dispersed mud and mud sheath from the casing inner diameter.
  • Before the cement slurry and behind the space, a bottom plug is pumped. As the plug moves down the string, it removes the left dispersed mud from the inner diameter of the casing.
  • A diaphragm on the plug gets ruptured due to the pressure exerts when the bottom plug seats are at the float collar. This helps cement to flow through it.
  • It twists the corner of the hole or toe end, located at the bottom of the horizontal well.The annular space between the casing and the formation is then filled.
  • By this way, after the full volume of cement has been pumped, a top plug is dropped and pumped behind the slurry.
  • The top plug then removes the leftover cement from the inner diameter of the casing and reach at the float collar.
  • It then rests on the bottom plug to cause a pressure. It also indicates that the cement has been displayed.
  • Both the top and bottom plugs are always different.
