This article is written for Data Header used in oilfield high-pressure flowline and manifold connection 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.
Data headers are available as union-end data headers and API flanged data headers. Working pressure is 6,000 psi (42 MPa) to 15,000 psi. Service condition: standard and H2S service, meeting NACE MR0175.
The data header is used for pressure, temperature, and other data-acquisition interface connections in pup joints and manifold systems. Union-end and API flanged connection types are available.
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 Data Header, 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
Data Header 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 Data Header quickly.
