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 manifold mainly includes a combined high-/low-pressure manifold, sand-adding manifold, and pump discharge manifold. It is important manifold equipment used for high-pressure fluid transfer and distribution in oil and gas well fracturing operations. During fracturing, high-pressure high-flow pumps inject viscous fracturing fluid through the fracturing manifold into the reservoir to create fractures, improve reservoir flow capacity, and increase well production.
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.
A component may be correct by itself and still create field problems if adjacent equipment uses a different pressure class, Fig system, flange rating, bore size or flow direction. System matching should be checked before installation.
Key points to confirm
For Fracturing 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
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.
