Drill Pipe/Casing Protectors

The Regal Drill Pipe/Casing Protectors (DPPs) are steel reinforced rubber pads which, when installed around the drill pipe, offer an expandable downhole wear surface. They are designed to protect the casing I.D. from drill string wear. They are recommended for deep holes, deviated holes, high speed drilling, high torque and offshore applications.
