Materials Ss410 and Tungsten Carbide Positive Choke Bean for Choke Valve

Product Description

Stainless Steel bonded Tungsten Carbide Choke Stems and Seats for Oil and Gas Industry  
 

Choke bean is often used in the positive choke valve for controlling the flow. Zonco choke bean is same as Cameron type H2 big john choke bean, body Material: 410SS, lined with Tungsten Carbide (YG8), to protect them from corrosive and abrasive wear. 

On one side of the choke manifold, calibrated choke beans are used to control flow rate through the fixed choke box. Each bean is a specific diameter, usually in graduations of 1/64-1/32 inch, Depending on the type of equipment used, the size of the choke bean can be as large as 3 inches. The choke Bean in all standard API-6A available sizes. 

The features: 
1. Good wear and corrosion resistance 
2. Long lifetime
3. Good working performance
4. One stop customized service
5. Standard export package
    

 

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.
