Mud motor is one of the most widely used downhole tools in oil #Directional Drilling,in which PDC Bearing is the most important parts.
ZONCO adopt advanced vacuum sintering process and HIP sintering process to perfectly combine sintered cemented carbide layer and steel body of Tc bearing ,significantly enhance its resistance to abrasion,erosion and corrosion from mud fluid,thus ensure that downhole motor could stably work in directional drilling.
PDC bearing is a more innovative design in drilling motor compare to PDC bearing which ZONCO could also supply and welcome to consult!
Our PDC and TC (Tungsten carbide) Radial Bearing advatages are as the following:
1) Highly resistant to abrasion, erosion, corrosion, and mechanical failure
2) Extremely resistant to chipping, cracking, and flaking which are inherent problems in cladding or welded overlay processes
3) High heat conductivity eliminates thermal cracking
4) Proprietary design eliminates catastrophic downhole radial bearing failure
5) Carbide tile and matrix design ensures extended life compared to cladding or welded overlay designs
6) Inner and outer components can be reconditioned.
7) The hardness of body surface can reach 30-37 HRC.
Company Introduction:
Zonco has been specialized in customizing various kinds of non-standard tungsten carbide wear resistant components for more than 10 years.Our products and technologies have been widely applied in the fields of oil & gas (such as downhole tools(dill bits, chrismas tree, RSS, PDM), wellhead equipment, subsurface valves, MWD/LWD Tools) and chemical engineering, subsea, valve, pump, mechanical equipment. Mainly used in harsh operating conditions include severe abrasion, erosion, corrosion, high temperature, high pressure and strong impact. we are able to manufacturing all kinds of wear resistance valve parts based on customer's drawing and material requirement, support hardfacing process based on customer's technique requirement. since most of our products are customized and not suitable to show for other customer, welcome to contact us for OEM service.
Our main products Types:
1. Carbide nozzles for Oil Drill Bits, nozzle sleeve, bushing.
2. Carbide parts for MWD/LWD tools, such as rotor,stator,liner,sleeve, plate,retainer,shroud etc.
3. Carbide Parts for downhole tools,such as torque impactor, centralizer, fracturing nozzle, stationary valve Assy and OSC valve Assy in Hydraulic oscillator etc.
4. Carbide Radial Bearing, such as TC bearing, PDC bearing.
5. Valve Trim, such as valve plug, stems, seats, cage, choke bean,choke stem.
6. Steel bonded tungsten carbide Assy and Surface Technology on Steels (PTA,HVOF, Boriding).
7. Other customized carbide parts based on client's drawings etc.
