Audited Supplier
2. Carbide wear parts for oil and gas industry, wellhead assembly (eg. Christmas tree, multistage choke manifold)
3. Customized tungsten carbide choke valve stem and seat according to drawings.
Hardened alloy Steel Stems and Seats are widely used in Adjustable Needle & Positive Choke assemblies. Stainless Steel or stainless steel with Tungsten Carbide tips for Abrasive and or Sours Gas Service are available on request. Positive Choke assemblies are furnished less flow bean and may be converted to Adjustable Choke assemblies by replacing the blanking cap assembly and flow bean with the appropriate adjustable bonnet assembly and seat.
Customized various kinds Valve Plugs and Seats
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.

What is surface treatment and its advantages?
Surface treatment is an additional process apply cemented carbide to the surface of a material for the purpose of adding functions such as erosion resistance,corrosion resistance and wear resistance or improving the hardness,by which lower the cost compared to the cost of using entire cemented alloy,and remain the alloy good performance upon the material.
Surface treatments can be broadly classified into removal processes, such as scraping or melting the surface, and additive processes, such as painting,coating which add cemented carbide to the surface.there are four technical surface treatments we have in image below as additive processes to highly improve property of wear resistance and erosion resistance.
