PRP-R1 Cement displacement plug

Cement displacement plugs are used during cementing (grouting) operations in the well and are designed to clean the inner surface of the casing string, separation, and prevent mixing of cement (grouting) mortar and buffer fluid pumped in front of it.

Operating temperature, °С: from -40 to +130
