Cemented Carbide Nose Cap 650/1200 For MWD & LWD
Description
The tungsten carbide lift valve is one of used parts in MWD and LWD to help sending slurry pressure and other information back with pulse signal. The tungsten carbide lift valve stretch out and draw back to change the pressure of the mud column and transmits wireless signals.
Tungsten carbide material LWD and MWD precision parts consist many product series:upper pan calve complete,lower pan valve,piston,bushing,nozzle of the liquid flow control and automatic push device of vertical drilling tools,flow deflector,vane wheel,vane wheel axle,vane wheel box,nozzle of the self-activated oscillating-rotating impact drilling tools,lift valve core,flow limitation ring,flow limitation chamfer,nose cap,flow divider,flow,spacer sleeve,pulse hole valve,oscillator of self-activated,upper and lower bearing sleeve and wear sleeve of the pulse generator of MWD and LWD,and nozzle,TC bearing and sleeve of the under well well tools.
Cemented carbide wear parts are mainly used to the vertical well drilling tools,self-activated oscillating-rotating impact drilling tools and MWD and LWD with the functions of flow diversion,flush and seal of slurry and feed back of the slurry pressure and pulse signal in the adverse working conditions of high pressure,high speed flushing of sand and slurry,high temperature,fatigue wear,gas and liquid corrosion in oil and natural gas prospecting.
