Apply Pressure And Lockdown Simultaneously

Instead of requiring separate trips, the locking technology on Dril-Quip’s SS-15® RLDe induces preload at the time of installation. This increases resistance to bending and fatigue life – no additional tooling is necessary. With two million lbs. of lockdown capability, the SS-15® RLDe can incorporate a pressure-balanced annulus shut-off valve that closes off the flow-by between the casing after being cemented into place.

Our DXe® Wellhead Connector locking profile can also be added to the wellhead. Popular in shallow-water applications and on heavy floating rigs, it delivers industry-leading structural capacity and fatigue resistance while occupying less real estate on the top wellhead face. A standardized quality plan eliminates the need for independent purview, expediting delivery.

System Features

  • Lowers carbon emissions by eliminating manufactured hardware and reducing the time it takes to drill a well
  • Enables casing hanger/seal assemblies to be run in one trip
  • Eliminates the need for extra lockdown devices
  • Eliminates up to five trips, saving time and money
  • Extended service life; field-proven in extreme HPHT conditions
  • Unmatched bending, tension, and load-carrying capacities
  • Accommodates 30- to 36-inch conductors
