This article is written for Cementing 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 cementing manifold is used for high-pressure cement-slurry transfer and process control in cementing operations. It steadily delivers slurry discharged from cementing pumps to the wellhead to complete cement injection, displacement, and related high-pressure fluid operations. Plug valves are used as the main control valves, providing reliable opening and closing, stable pressure-bearing performance, and convenient field operation.
Cementing manifold working pressure ranges from 5,000 psi (35 MPa) to 15,000 psi, and nominal bore is 2 in to 3 in. Connection type can be API 6A flange or union-end connection. The product is suitable for standard and low-temperature service and can be selected according to cementing pump units, wellhead connection type, and field line layout.
Inspection before installation should focus on identification marks, sealing faces, threads or flange faces, visible damage and document consistency. The goal is to confirm that the item received is the same item approved for the job.
Key points to confirm
For Cementing 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
Cementing 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 Cementing Manifold quickly.
