This painted WPB carbon steel flanged end cap enquiry follows the A234 and B16.9 title references. API 5L is also mentioned, but its relevance to the offered cap needs clarification. Establish the selected component and supply documents before relying on the combined standards wording.

Reconcile the title range with the recorded cap option

The title describes half-inch to 48-inch supplies, while the only variant is Cap / 10 mm / Carbon Steel. Request one consistent nominal size and clarify what the metric label represents. The single variant does not verify availability across the entire inch range.

Obtain actual outside dimensions, wall and tolerances plus the flange face, drilling, mating component and sealing details. Allocate the four-inch overall length, quarter-inch mounting hole, round shape and hexagon head from the table. Its inch measurement entry does not independently resolve the size discrepancy.

Separate the governing cap documents and API reference

Identify exact A234 and B16.9 documents, editions, selected cap scope and WPB material condition. Ask whether API 5L refers to the cap, material supply or associated pipe requirement, and obtain supporting records. Do not treat the references as equivalent or as verified certification for this component.

Request certificates, traceability and manufacturing records addressing the machining entry. Painting needs a defined system, preparation, thickness and acceptance. No seamless, forged or butt-weld route is provided. Corrosion, chemical, UV, flexible and underground descriptions require evidence for the intended exposure.

Agree project conditions and acceptance documentation

Provide medium composition, operating pressure, temperature, cycling, external environment and mechanical loads. Require selected material, coating, joint and rating evidence. Low Pressure and Class 150 do not supply numerical operating limits here; agree dimensional examination, testing and documentary acceptance rather than assuming the broad industry list qualifies every use.
