Our cementing plug and dart technologies remove previous fluids with efficient fins that cleanly wipe the inside diameter (ID) of the casing or drillpipe.

Our darts provide a reliable surface indication of downhole cementing events, including the pressure increase that occurs when the top plug bumps on the float equipment to signal that displacement is complete. We manufacture a comprehensive line of standard and customized cementing plugs and darts for any application:

• Casing wiper plugs separate fluids during cement curing in surface casing strings.
• Wiper darts separate fluids in the drillpipe or tubing string for inner string cementing.
• Stage-cementing wiper-plug sets separate fluids in the casing or liner ID and open or close the stage tool.
• Multiple latch-in high-pressure rupture plugs are run when cementing production or completion strings and in wet shoe applications.
• Subsurface release (SSR) plug system separates fluids in the drillpipe and liner or in the casing string in subsea casing- or liner-hanger systems.
