2. Two types of cementing plugs are used in the cementing process,bottom cementing plug and top cementing plug.
3. The top cementing 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 bottom cementing plug is launched ahead of the cement slurry to minimize contamination by fluids inside the casing prior to cementing.
4. Our cementing plugs including standard type and non rotating type, customers choose the right cementing plugs according to float equipment type.
5. Inner material of cementing are aluminum alloy or Nitrile Butadiene Rubber , the plugs are easy to drill and used in high temperature.The top plug and bottom general have different color in production for easy usage in operation.
