Choke valve, a valve that raises or lowers a solid cylinder which is placed around or inside another cylinder which has holes or slots. Used for high pressure drops found in oil and gas wellheads
The choke valve, a main component of Christmas tree, is design to control production rate of the oil well, with working pressure up to 15000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel to move the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is design to accomplish control of production rate by changing flow beans. Features: The coupling nut used for connecting the bonnet and body allows fast make-up and break-out. Stem tip and bean adaptor are fabricated from special carbide alloys for corrosion and abrasion resistance. Ã?Â·Indicator lens with scale marks allows the operator to know stemÃ¢??s position and actual orifice area. Ã?Â·Turn hand wheel counter-clockwise and the valve will open; turn hand wheel clockwise and the valve will close. Main technical datum Working Pressure: 2,000-20,000psi Nominal Dimension: 2-1/16Ã¢?? ~ 7-1/16Ã¢?? Working Temperature: P U Product Specification Levels: PSL1 ~ 4 Performance Requirement: PR1 ~ 2 material Class: AA ~ FF Working Medium: crude oil; natural gas Adjustable choke valve Ã?Â·Valve needle and spool are made of tungsten carbide, with sufficient corrosion resistant, antieroding and wearable capability. Ã?Â·The two kinds of adjustable choke, pintle type and the sleeve type could apply to wellheads& X-mas tree and choke manifold. Positive choke valve Ã?Â·Material of choke bean is fabricated from ceramic and tungsten carbide, with sufficient corrosion resistant, anti-eroding and wearable capability. Ã?Â·It adopts union bonnet so as to change choke quickly Ã?Â·It has application in wellhead& X-mas tree and choke line.
1.Application Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas well in the course of drilling,as it is,the device is adopted to execute new drilling-well's technique of balance pressure,which can avoid pollution of oil-layer,improve the speed of drilling and control blowout effectively. One end of the device connects with the side flange of BOP spool.When BOP closes,it can control the finite pressure from casing by adjusting the choke valve's opening,so balanced drilling can work under minimum pressure-difference. 2.Configuration The choke manifold consists of choke valves,gate valves,line pipes,fittings,pressure gauges and other components. 3.Working Principles When the pressure inside the well rises,opening/closing the choke valves(including manual chokes,hydraulic chokes and positive chokes)on the choke manifold can allow the release of the fluid inside the well so as to control casing pressure,which can be directly blown out through the gate valve if the casing pressure is quite high. 4.Pressure Ratings The kill manifold is available in pressure ratings of 2000psi,3000psi,5000psi,10000psi and 15000psi,and also can be available upon customer request.
