Product Description

Kelly Valve/Cock
Ke lly valve also named Kelly cock or drill pipe safety valve. It is a hand control valve in drill string circulating system and it is one of the effective tools to prevent blowout. Kelly valve is divided into Upper Kelly Valve and Lower Kelly Valve. Upper Kelly Valve is connected between swivel sub and Kelly. Lower Kelly valve is connected between lower end of Kelly and top of drill pipe or lower end of Kelly save sub. Rotating the wrench of full opening safety valve 90° to realize on and off. In the drilling operation, in order to avoid malignant accidents, Kelly valves should be connected to both end of Kelly to prevent the loss of drilling fluid and blowout.

Arrow Type Check Valve
Arrow type check valve (drill check valve) is a kind of important inside blowout tool, usually used in the oil and gas drilling and workover. It works with the drilling tool into the well, in the process of drilling and workover in case of overflow, kick, or positive cycle to stop, the arrow type check valve will shut down rapidly under the action of reverse circulation pressure inside drill tools and spring force, cutting the channel within drilling tools, thus play a blowout purpose within drill tools.

Full Opening Safety Valve
Full opening safety valve is a hand control valve in drill string circulating system, and it is one of the effective tools to prevent blowout. In the drilling operation, in order to avoid malignant accidents, full opening safety valve shall be connected between drill pipes in drilling process. The special wrench of full opening safety valve may rotate 90 °according instruction to switch on and off. In well repair operation, whether need to lift the drill pipe or not, it is best to install opening safety valve as prevention.

Retrievable Drop-in Check Valve
Retrievable drop-in check valve is a drill string inside BOP valve. It has a landing sub and connected to the right position of drill string, then put into the well, to help the check valve assembly into place. Retrievable drop-in check valve is one kind of one way check valve to prevent back flow when well kick. It allows fluid down to return well.This valve can control pressure in the drilling process and improve the well control obviously. As long as drop in, it can be into place in the land sub automatically, easy operate, so that achieve the purpose of the blowout control. In addition, compared with other previous drop- in check valve, the disassembly of this check valve can save a lot of manpower and material resources.

Drop-in Check Valve
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 oncetimedrop 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.

FPJ Inside BOP Valve
FPJ Inside BOP Valve is a large pressure drop check valve. Valve seal is the arrow type valve seal, the arrow type check valve will shut down rapidly under the action of reverse circulation pressure inside of drill tools and spring force, cut off the channel within drilling tools, thus arrieved prevent a blowout purpose within drill tools. It can be reserved on the platform, or release its top open device, then install it between drill pipe and drill bit, to prevent the high pressure oil and gas spewing from the drilling tools. A special release tool makes the valve in a normally open state, could allow backflow throudh.This release tool is per-installer in the float valve and the whole assembly kept ready on the platform for quick installation ai the first sings of backflow when drill pipe is pulled out of the well.
