Choke Manifold - Well Testing Choke Manifold

Choke manifold is a system of valves and chokes for controlling the flow from the well usually has two flow paths, one adjustable choke used primarily for cleaning the well up and facilities to install and change choke of fixed sizes for a more accurate flow control during main well flow periods.

 Each flow path has two closing gate valves which are used to direct the flow through either of the chokes or the chokes or the bypass and to provide isolation from pressure when changing the fixed choke. A dual isolation, double block and bleed valve arrangement is recommended for high pressure, sour gas and sand frac clean ups.

Choke manifold is used during well testing,. The positive choke has a fixed diameter and the size of the orifice on the adjustable choke can be varied. In addition the adjustable choke allows fixed chokes to be switched out as needed without stopping the well, increasing the flexibility of the overall system.

Choke Manifold has these principle functions:
　• It allows wellhead pressure to be controlled, improving safety. 
　• It maintains a certain flow rate, as required for testing. A test can require different flow rates over several time periods, requiring the use of different choke sizes. 
　• It prevents formation sand from entering the well by limiting the flow rate. Limiting the flow rate reduces the speed of the fluid, which in turn, minimizes the amount of sand entering the well. 
　• It also prevents water and gas coning by limiting the flow rate. 
　• It is also used to ensure that the flow is critical, meaning that the pressure fluctuations downstream of the choke manifold do not affect downhole pressure and flow rate of the well. 
Our Choke manifolds are available in 5,000; 10,000; and 15,000 psi, all bore sizes.

Choke Bean - Ceramic Choke Bean - Tungsten Carbide Choke Bean

Choke bean is often used in the positive choke valve for controlling the flow, our positive choke beans are similar as Cameron type H2 big john, Body Material: 410SS, lined with Tungsten Carbide or ceramic. 

Feature:

• 1. Choke bean size: 4/64" ~ 192/64" increment with 1/64".
• 2. Both ceramic liner and tungsten carbide liner are all available.
• 3. Medium: oil and gas water, sand.
• 4. Customizable size.

• 5. Tungsten carbide and ceramic choke bean are all available.

Adjustable Chokes - adjustable choke valve

Adjustable choke valves are often used in the oilfield when drilling，testing，production, our adjustable choke valve is designed and manufactured in accordance with API 6A and API 16C standard and improved from Cameron H2 series adjustable choke valves. They are easy for operation and simple to maintain.

Our adjustable choke valves have many sizes and pressure ratings used for oil field application

 Feature:

• 1. Manufactured and tested in accordance with API 6A.
• 2. Carbide alloy is embedded into stem needle of valve, seat.
• 3. Flow adjustment is indicated on a measuring scale.
• 4. composite rubber-plastic stem lip packing reduces operating torque.

• 5. Max orifice:1"-3".

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.
