Choke Manifold Kill manifold A choke manifold is used to lower the pressured from the well head. It is necessary for controlling the well kick and implementing oil and gas well pressure. It consists of choke valves, gate valves, pipes, fittings, and pressure gauges. It is needed so that if one choke has to be taken out of service, the flow can be directed through another one. We manufacture 5 types of pressure grades: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa and specially customized accordance to the clients requested specifications. In case well head pressure releases, drilling fluid can be pumped through the down hole by the kill manifold to balance the bottomhole pressure so as to prevent well kick or blowout. In addition, the blowout pipelines connection can drain fluids from the well directly to release bottom-hole pressure. Cement can also be injected into the well through the kill manifold during the cementing operation as well as water or other agents can be injected when necessary. Check valves ensure that fluids flow in one direction through the down hole where no backflow occurs. The kill manifold consists of check valves, gate valves, pressure gauges and pipe lines. One end of it is connected to the drilling spool, and the other to the injection pump. Both choke manifold and kill manifold are made in conformity with API 16C standard. Xiongyue kill manifold has 5 classes of working pressure: 14MPa, 21MPa, 35MPa, 70MPa,105MPa. Rated pressure of all the pipe lines, gate valves and check valves must match that of the BOP. Kill manifold is not supposed to be used for regular drilling fluids injection.

Check valve Positive choke valve This product is designed and manufactured in full compliance with requirements of API Spec 6A Specification for Wellhead and Christmas Tree Equipment, which can match and be interchanged with any other equipment of API Spec6A. The sealing of the check valve is done by the metal-to-metal type between the valve trim and the valve body applied by medium pressure. The greater the pressure is, the tighter the sealing. Pipe line pressure can be borne in valve cavity at all times. Valve body is made of forged alloy steel with strong mechanical properties, which withstands high pressure and is safe and reliable. Valve bonnet and body are bolt-connected, reliably sealed by sealing rings in bonnet and body wall sealing. This leaves very small space between bonnet and body (actually no space as designed) to reduce the corrosion from corrosion medium on bolts and holes and lower the bolt load. Valve trim and valve body sealing surfaces are bead-welded with hard alloy, so that they have superior performance of wear and corrosion resistance. The valve trim is made of anti-sulfur steel, and other parts are with hardness restriction, so that the valve can be used in H2S environment impact.

Needle structure is mainly applied in Christmas tree, barrel, wedge and orifice structure in choke manifold.
Hydraulic safety valve Plug valve Hydraulic safety valve consists of safety standby valves and hydraulic actuators. It is the executive unit of the well safety system. Under normal condition, high pressure oil is pumped into the cavity in the upper part of the actuator, pressing the spring at the bottom to open the valve. ln case the well head is under dangerous pressure, control unit will response to the signal passed from the sensor, and unload pressure on the cylinder and the spring will bounce back and drive the valve stem to close the valve and the well assembly, ensuring equipment safety. Hydraulic actuator installed in reverse action gate valve Plug valve is an indispensable device for connecting high-pressure manifold during well cementation and fracturing in oil fields or mines, and also applied in similar high-pressure fluid control. With the characteristics of compact structure, easy maintenance, small torque demands, quick and easy operation, the valve is an ideal device for well cementation and fracturing.

Ground control assembly High-pressure movable elbow Resident fluid should be guided to the separator and burner after flowing to the ground through the drill pipe of the pipeline during testing which can control the pressure and flow rate of the fluid safely and effectively. Connected with the test string the control head is applied into rotating or nonrotating motion, into 35MPa, 70MPa and 105MPa working pressure from its loading capacity. It can let high-pressure fluid flow out of string, and pump fluid into the well. It is used to control fluid pressure and the flow manifold. Rated working pressure of floor manifold: 35MPa, 70MPa and 105MPa. It is used to connect high-pressure manifold of control head, floor pipe and relief pipeline, which consists special heavy seamless steel pipe union and movable elbow. Rated working pressure of movable manifold is 35MPa, 70MPa or 105MPa. The high-pressure movable elbow is a metal pipe joint with ball bearing that are 1 to 4 with working pressure of 14-140MPa ( 2000psi 20000psi). It is feasible to provide various models of movable elbows used under normal temperature, low temperature and sulfurous gas as well as the maintenance packages. The movable elbows have 2 types: major radius elbow and short radius elbow. The major radius movable elbow has a smooth drift diameter, which can minimize the resistance generated when liquid passes, the resistance to erosion and corrosion of fluid for the wall thickness at the turning position of major radius elbow is better than that of short radius elbow. However, short radius elbow is also used in consideration to limit the pressure for field installation. Movable manifold should be regularly inspected, lubricated, hydraulic sealing tested and its seal ring replaced for safety.

Line pipe threaded, pipeline threaded, butt welded or gland sealed connection are all suitable components to use. Hydraulic ram BOP is an important part of well control device, featuring flexible switch, labor-saving operation, safe usage, simple maintenance, etc. 1) Structure Descriptionmain value in order to close the well in the mouth automatically. For dual-face rant the upper and lower faces are symmetrical. For drilling tools in different sizes, only the semi-annular rubber sealing ring and the ram pressing block need to be replaced, and other parts are for common use. Single-face ram is not supposed to be used upside-down. Shearing ram will cut the drilling tool and seal up the wellhead. Variable bore ram is used to meet the demands of drilling tools in different sizes. Annular BOP 2) Ram Sealing Description Effective sealing of a wellhead depends on sealing in 4 different positions.i.e., sealing between upper side of ram and housing, sealing between front end of ram and the pipeline, sealing between side gate and housing, and sealing between piston rod and the side gate. 3) Ram Locking Operations By turning a hand wheel, the rams can be locked manually. But it can not be unlocked by the manual locking device. To unlock, be sure to reset the manual device, and then unlock the ram with hydraulic power. Operating principle A hydraulic control system is used to close or open the annular preventer. When used to close the BOP, high pressure oil is directed to the dosing chamber positioned at the lower side of the Piston, causing the piston to move upwards. The packing unit is compressed by the moving piston. Connected with the BOP top cover, the packing unit cannot move upwards and is forced to the center of the well to pack off a string or seal off the well. When opening the well the reverse valve of hydraulic control system is shifted, directing the high pressure oil into the opening chamber at the upper side of the piston to drive the piston downwards. The closing chamber will then recede, stopping the pressure on the packing unit allowing the well to open.
