Product Description

Drop-in Check Valves

 

Drop-in check valve is a drill string inside BOP valve. It also can be used for block off drill pipe on all kinds of offshore drilling floating equipment. Only after block off borehole and the annular space outside the drill string, that can be complete tasks to prevent blowout accident, as long as block off high pressure flow in the bore of drilling string, the well blowout is easy to control which occurred between borehole and the annular space outside the drill string.

It has a landing sub, which connect to the need position of drill string then put into the well, help check valve into place, drop-in check valve is a kind of single flow check valve, stored on the platform, when found blowout omen, drop it into drill pipe bore, just once time drop in can be into place on the land sub automatically, When high pressure flow of downhole, the check valve could cut off high pressure flow of upward jet in the drill string.
