Blowout Preventor
Our company produces blowout preventer and hydraulic control systems, which can meet the purposes of well drilling, under-balanced drilling, underground operation, non-killing well pressurized operations etc. With full range of specifications, bore size from 52-540(2 1/16in-21-1/4in), pressure rating from 7MPa to 105 MPa (1000psi-15000psi). The H2S resistance performance complies with NACE MR-0175:2003 requirements. It is applied to oil extraction, perforation, test, operation, pressurized operation and under-balanced drilling.Principle: When the oil gas pressure within the well is pretty high, the blowout preventer can close the well (tightly closing). When the heavy mud is entered from the inner pressure of the drilling rod, there are four channels under the blowout preventers of the shutter, which can replace the mud suffered from gas invasion and enhance the liquid control pressure within the well to pressurize the injection of the oil gas.Application: the blowout preventer is divided into the common blowout preventer, ring blowout preventer and rotary blowout preventer, sealing shutter ans semi-sealing shutter type. The sealing shutter can seal the whole well port while the semi-sealing shutter only seal the ring section of well port with drilling rod, Ring blowout preventer is started in emergency circumstances and it is able to deal with the drilling tool and well. Rotary blowout preventer can conduct the edge blowout operation.Function: the well port shall be closed during the process of drilling, oil trial, well repair and well operation, so as to be preventive from well injection, which, as a result, protects the equipment and protect the safety of the working personnel.Drift diameter codeSpecification187 1/16"239"2811"3513 5/8"Product code:SFZ: manual single ran BOP2SFZ: Manual double ram BOPFZ: Hydraulic single ran BOP2FZ: Hydraulic double ran BOPFH: Spherical rubber Annular BOPFX: Rotating annular BOPSingle Ram BOPBoth the design and manufacture of the u-type bop with the ram block meet the requirement of API Spec 16A and GB/T20174 drilling and oil-production equipment. And all u-type bops are provided with the ram block of various sizes.It consists of a high-grade front-positioned rubber core and another rubber core on the top, which, together with the in-between flange, enables the bop to work in extreme circumstances such as at extremely high or low temperature, or under acidic conditions.Nominal bore diameter(in)Operating pressure psi(Mpa)A(mm)B*(mm)C(mm)D(mm)E(mm)F(mm)G(mm)H(mm)Net weight（kg)7 1/// 5//Double Ram BOPBoth the design and manufacture of the u-type bop with the ram block meet the requirement of API Spec 16A and GB/T20174 drilling and oil-production equipment.

It can be equipped with various rams. With the best quality front ram rubber, top ram rubber and flange sealing stacks, ram blowout preventer (Cameron style) can work during the extreme working condition including extremely high or low temperature and extreme chemical environment.Structure Features●The pressure‐bearing components are forged, so it has better strength and impact toughness;●Floating sealing is applied to the cylinder cover and the open/close of the cover is realized by hydraulic power, so it is quick and convenient for changing rams;●The auxiliary oil cylinder affords a smaller volume with same function;●The standard configuration includes a manual locking device, which ensures the ram is closed tightly in case there is a hydraulic pressure loss;●Both the manual and hydraulic locking device and the auxiliary oil cylinder can be installed flexibly into different positions according to customers’ requirements, and the installation positions can be changed easily.Shaffer StyleRam Blowout Preventer (Shaffer Style) is designed and manufactured according to API Spec 16A standard. It can be equipped with various rams from 2‐3/8"~13‐3/8", also Blind and Shear Ram. Structure Features●Body and side door are made of alloy steel;●Use seal rings assembly to improve sealing of side door;●Use floating type ram. Front ram rubber is separated from top ram rubber, making it more reliable in sealing and easier to change;●Use buried oil way inside body. Loading hinge is separated from hydraulic hinge;●Compact hinge structure makes it easy to assemble and disassemble;●Use arc-shaped body chamber with four round corners as transition section to reduce stress peak value whenever bearing the pressure;●Ram cavity can be fitted with ram assembly of same type BOP made abroad;●Flange grooves are stainless steel lined.If you have any further requirements, please feel free to contact us
