  • Inquiry

Product feature: 

1. Heat resistant; very good wear resistant

2. HIP sintering, High hardness. 

3. Good impact toughness, chemical stability.  

4. Excellent performance and good wear/corrosion resistance                                                                                    
5. High machining accuracy/precision             

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.
