Blowout Preventers

Control the release of well fluids and gases

With a blowout preventer (BOP), you can create a pressure-tight seal at the top of the wellbore to restrict flow from the well. Our inventory includes a variety of annular and ram-type BOPs, specialty BOPs for large casing strings, snubbing units for live-well applications, and control units for remote operation. As a single source for your BOP needs, we perform testing, service, and installation.
