Description

China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of choke manifold in China, featured by competitive price and fast delivery. Welcome to buy high quality choke manifold in stock here from our factory.

Choke Manifold is a necessary device to control the well kick successfully and execute the pressure technology on an oil/gas well in a drilling operation, the device is adopted to execute the new drilling well's technology of balance pressure, which can avoid pollution of oil layer, improve the speed of drilling and control blowout effectively, maintaining wellhead protection through pressure relief and fluid discharge. It is used to pump kill fluid into the wellbore for well control operations, preventing accidents and ensuring production safety.

1. The manifold consists of choke valves, gate valves, line pipes, fitting, pressure gauges, and other components.

2. Structural Form: Single wing, double wing, multi-wing or integral design;

3. Control Method: Manual, hydraulic, with control cabinet for remote control capability;

4. Base Type: Two-tier multi-level lifting or cantilever type.

5. Sizes: Available in a Nominal Bore size: 2 1/16" to 4 1/16";

6. Other data are as follows:

The API 16C specification provides strict technical requirements and quality control standards for its design, materials, construction, testing, and certification when used in oil and gas surface production operations.

Adhering to the Spec.16C guidelines offers several key benefits:

1. Safety - Compliance ensures a manifold is fit for purpose in hazardous well control applications.

2. Reliability - Stringent metallurgy, quality control, and manufacturing process requirements improve equipment reliability in continuous service. This minimizes unplanned downtime and mitigates operational risks.

3. Interoperability - Standardized connection points, valve interfaces, and dimensional requirements ensure integration with other wellhead equipment and instrumentation is seamless.

4. Performance - Spec.16C meets pressure, temperature, and service life metrics necessary to handle production from demanding wells.

Choke manifold function

(1) To carry out well-killing operations through the throttling effect of the choke valve, replacing the contaminated drilling fluid in the wellbore, while controlling the casing head pressure and tubing pressure, restoring the bottomhole pressure control of the drilling fluid column, and preventing a blowout.

(2) To reduce wellhead pressure through the pressure bleeding effect of the choke valve, achieving a "soft shut-in" of the well.

(3) To lower the casing head pressure significantly through the large flow bleeding effect of the bleed-off valve, protecting the wellhead blowout preventer stack."

FAQ

Q: Can you provide full material traceability and certification?

A: Yes, our quality management system provides full material traceability from melt to final delivery. All required material certifications are provided per order requirements including mill certificates.

Q: How do you package and ship pipe?

A: To prevent damage in transit, we package pipes in wooden crates or metal boxes. For marine transport, a pipe is sealed in vapor corrosion inhibitor bags or coatings. Shockwatch indicators track handling. We coordinate all required logistics.

Q: What inspection and testing capabilities do you offer?

A: Chemical analysis, mechanical testing, microstructure validation, hydrostatic testing, ultrasonic examination, magnetic particle examination, visual inspection, and more.

Our products are fully customized for specific well conditions and tested to meet all design standards. With fast delivery and expert service, we are the ideal manifold partner for your oilfield operations. Contact our team to discuss your requirements and get a quotation.
