DOYLES offers remanufactured GK, GL and MSP annular BOPs that operate with only two moving components - the piston and packing element. GL annular preventers are utilized both offshore and on land-based rigs. The secondary chamber of a GL acts as a secondary closing chamber to increase reliability and safety. GK annular preventers are typically utilized for land-based rigs but may be used offshore as well. The GK has many of the same features of the GL with few parts.

Compact Annular Blowout Preventers (BOP)

DOYLES compact, annular-type BOPs seal reliably on almost any size drill pipe, tool joints, drill collars, kelly, casing or wireline. The sealing element lasts and retains its ability to return to the fully opened position. Available in bolted cover, they are lightweight and provide positive pressure control for stripping drill pipe.
