Choke bean is often used in the positive choke valve for controlling the flow, DEENPU choke bean is same as Cameron type H2 big john choke bean, body Material: 410SS, lined with Tungsten Carbide (C10 or C25) or ceramic, 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-inch, and is screwed into the choke box. These are the most common sizes (in inches) of choke beans used: 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 3/4, 7/8, 1, 1-1/4, and 1-1/2. Depending on the type of equipment used, the size of the choke bean can be as large as 3 inches.
We can do the QPQ treatment on the body of choke bean, to enhance the surface hardness, it shows black color as below:
Feature:
- 1. 100% Interchangeable with Cameron H2 Chokes.
- 2. Choke bean size: 4/64" ~ 192/64" increment with 1/64".
- 3. Both ceramic liner and tungsten carbide liner are all available.
- 4. Medium: oil and gas water, sand.
- 5. Customizable size.
