Product Description
Zhongshi Brand wiper plugs are featured in high performacnces and dsigned with a positive wiping action to ensure a clean casing.

Size Range: 4"-20" ( Special sizes can be customized. )

Two Parts: Top Plugs & Bottom Plugs

Top Plugs:

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.

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.
