Cementing Plug


Cementing Plug


Cementing plug also called wiper plug is a rubber plug used to separate the drilling mud from other fluids. There are two types of cementing plugs, bottom plug and top plug. Non-rotating type and common type are two options for customers. We provide non-rotating type plugs that have locking teeth on both the top and bottom plugs and float collars, allowing the plugs to lock together during drill-out.




Common type cementing plugs


Common type top and bottom cementing plugs are manufactured with graded rubber that is fused onto a composite or aluminum core. Top cementing plug can be used when a dual plug system is not required and bottom cementing plug can be used when a dual plug system is required.



Non-rotating cementing plugs

Non-rotating top and bottom cementing plugs are designed to decrease drill out time. Non-rotating cementing plugs have the reinforced locking teeth that are built into the plugs. The plugs are made of high quality rubber with a plastic core inside. No metal parts are used.
