This article is written for Fracturing 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.
A fracturing spread may include low-pressure supply headers, high-pressure pump-discharge manifolds and an additive-feeding subsystem whose exact medium must be defined by the process design. The high-pressure manifold combines pump discharge and routes fracturing fluid—and proppant-laden slurry where applicable—to the selected well.
Cold working pressure ranges from 5,000 psi (35 MPa) to 20,000 psi. Nominal sizes include 2" and 3", meeting requirements for different pressure ratings, flow conditions, and field flowline layouts in fracturing operations.
In field layouts, the first question is where the component sits in the pressure path and what equipment it must connect to. The answer affects connection direction, pressure class, access for operation and future maintenance.
Key points to confirm
For Fracturing Manifold, we normally recommend confirming the following items before quotation, production or replacement.
- Applicable fracturing-service project/manufacturer specification and connection-profile drawings; identify API Spec 6A requirements only for specified valves or flanged interfaces. API Spec 16C is not the default specification for a fracturing manifold.
- Working pressure, test pressure, nominal size and bore requirement.
- End connection type, mating equipment, flow direction and installation space.
- Service condition: standard, low-temperature or sour service; for sour service, provide the environmental limits needed for NACE MR0175/ISO 15156 material selection.
- Required documents such as MTC, pressure test report, NDT report and third-party inspection.
Field use and inspection
Fracturing 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 Fracturing Manifold quickly.
