Inside Blowout Preventer

Wellhead Inside Blowout Preventer, Ball Check Valve, 105~165 mm, 35~70 MPa Ball check valve is a wellhead inside blowout tool, in order to realize safety control in drilling operation. It can effectively solve the overflow, kick occur in trip process. Put it into the well with drill stem and control the mud back flow pressure automatically. Please contact us for your ball check valve inquiries. Specification OD inch (mm) ID inch (mm) Connection Working Pressure (Mpa) 6 1/2

Inside Blowout Preventer Plate Check Valve, 35~70 MPa, 6 1/4'~7' Plate check valve is an important blowout control tool. Compared with other structure back pressure valve, it has high strength, large flow area, high temperature resistant, resistant to high pressure, drilling fluid erosion resistance and easy maintenance, etc. Please contact us for your plate check valve inquiries. Specification OD mm (inch) ID mm (inch) Connection Working Pressure (Mpa) 159(6-1/4) 65(2-9/16)

Inside BOP Tool Large Pressure Drop Check Valve, 35~105 MPa Inside BOP Valve is a large pressure drop check valve. The tapered plug of valve reduces the cutting action of the mud on the seat to ensure the closed position. Inside BOP Valve connected with drill string can protect swivel, hose and stand pipe. It can also be used before high pressure pump to prevent high pressure blowout. It is also a releasing tool to make the valve opening usually, and allows the backflow

Inside Blowout Preventer, FPJ Inside BOP Valve, Pressure Drop Check 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 prevent a blowout purpose within drill tools. It can be reserved on the platform, or release its top open device, then

Drop in Check Valve Drill String Inside BOP Valve, 35~105 MPa 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 blocking off borehole and the annular space outside the drill string, it can complete the task to prevent blowout accident. As long as high pressure flow in the bore of drilling string is blocked, the well blowout, which occurred between the borehole

Retrievable Drop-in Check Valve, Inside Blowout Preventer Valve, 35~70 MPa 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 backflow when well kick. It allows fluid down to return well. This valve can control pressure in the drilling

Inside BOP Tool Tubing Valve, Tubing Cock, 35~70 MPa, 4 1/8'~5 1/8'​ Tubing valve also named tubing cock, and drilling fluid can flow through the valve without pressure drop. This kind of valve is used as the tubing valves and install above tubing to control blowout, or to prevent drilling fluid loss when unload the tubing. Please contact us for your tubing cock inquiries. Specification OD inch(mm) ID inch(mm) Top Connection Bottom Connection Working Pressure (Mpa) 4 1/8 (105

Hand Control Full Opening Safety Valve, Inside Blowout Preventer, 35~105MPa 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

Inside Blow Out Preventer Arrow Type Check Valve 35~105 MPa, 3 1/16'~9' 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

Upper and Lower Kelly Valve, Kelly Cock, Drill Pipe Safety Valve, 35-105MPa Kelly 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

High Pressure Oil Drilling Float Valve, Inside Blow Out Preventer​ drill pipe float valve is one of necessary tools for oil drilling. It consists of float valve sub and float valve. The main function is to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt. When the well blowout or kick, the valve cover of float valve turn off the bore automatically, it will prevent well blowout accident. The working pressure of
