This article is written for Drill Floor 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 drill floor manifold is suitable for high-pressure fluid-operation systems on oil and gas drilling platforms and can be used according to drill-floor line layout and operating requirements. Working pressure ranges from 5,000 psi (35 MPa) to 15,000 psi, nominal bore is 2″ to 3″, and temperature class is -29 ℃ to 121 ℃ (PU class).
Service conditions include standard service and H₂S service environments. Sour-service products meet NACE MR0175 requirements and can meet the needs of drill-floor high-pressure manifold systems under different pressure ratings and operating environments.
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 Drill Floor Manifold, we normally recommend confirming the following items before quotation, production or replacement.
- Applicable standard or project requirement: 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
Drill Floor 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 Drill Floor Manifold quickly.
