This article is written for Well Test Choke Manifold used in oilfield high-pressure manifold and pressure-pumping service. The product should be confirmed by its real oilfield service position, not only by a short catalogue name. For API oilfield equipment, the useful specification combines pressure rating, nominal size, end connection, service condition, material or seal requirements, and inspection documents.
The well test choke manifold is essential equipment for testing oil and gas production wells. It is usually connected to wellhead equipment through wellhead lines and uses fixed-size choke beans for throttling control. It measures pipeline fluid pressure, temperature, and other parameters to support production and deliverability calculations while meeting fluid-control and data-acquisition requirements in well testing.
This manifold uses flanged connections and is equipped with slab gate valves. It is suitable for long-term continuous operation in various fluid environments and features reliable structure, long service life, and high safety. Nominal bore ranges from 2 1/16″ to 4 1/16″. Temperature class is -29 ℃ to 121 ℃ (P+U). Service conditions include H₂S service environments and meet NACE MR0175 requirements.
Reliable field service depends on correct make-up, clean sealing surfaces, proper support and regular inspection. High-pressure pumping creates vibration and pressure pulsation, so small installation errors can become serious over time.
Key points to confirm
For Well Test Choke Manifold, we normally recommend confirming the following items before quotation, production or replacement.
- Applicable standard or project requirement: API 6A / API 16C.
- Working pressure, test pressure, nominal size and bore requirement.
- End connection type, mating equipment, flow direction and installation space.
- Service condition such as standard service, NACE sour service or low-temperature service.
- Required documents such as MTC, pressure test report, NDT report and third-party inspection.
Field use and inspection
Well Test Choke Manifold should be checked as part of the complete high-pressure system. Sealing surfaces must be protected, connections should be clean before make-up, and the product should not be forced into alignment by side load, hammering or pulling. If leakage, abnormal operation or pressure-test instability occurs, the model, pressure, medium, photos and test conditions should be recorded for technical review.
Information for quotation
For new projects, please provide the line layout, operating pressure, medium, temperature, connection standard and document requirements. For replacement work, old-part photos, nameplate or body markings, end-connection close-ups and installation position help us confirm the correct Well Test Choke Manifold quickly.
