Cementing Plugs

Overview

Top-Co’s cementing plugs are used during cementing operations for wiping the casing ID clean of drilling fluids and providing separation between mud, spacers, and cement. They also prevent over displacement of the cement slurry and indicate when the cementing job is complete. All plugs are designed to fit in conventional cementing heads.
