This black painted WPB carbon steel pipe cap is listed with A234, B16.9 and seamless title references. Its connection wording combines Flange Connection and Butt Fitting. Confirm the actual design before selecting an interface, while using the supported carbon steel cap identity for the enquiry.

Clarify the cap interface and dimensional drawing

The only variant is Cap / 10 mm / Carbon Steel. Ask what the size label represents and obtain one consistent connection designation. The table states Flange, but the mixed title wording does not define a verified dual arrangement or complete joining detail.

Request nominal size, actual outside dimensions, wall and tolerances. The drawing should allocate four-inch overall length, quarter-inch mounting hole, round shape, hexagon head and inch measurement entries. Obtain applicable mating, sealing, face, drilling or end-preparation requirements after the selected interface has been clarified.

Verify WPB material and black painted supply

Identify governing A234 and B16.9 documents, editions, selected scope and WPB material condition. Request certificates, traceability and manufacturing records supporting seamless supply and the machining entry, including examination criteria. A title reference does not establish conformity of the offered cap.

Black Painted describes colour and treatment without defining paint chemistry or performance. Specify coating system, preparation, thickness, curing and finish acceptance. Require evidence related to actual corrosion, chemical or UV exposure; flexible and underground labels also need project-specific verification.

Complete the operating and inspection acceptance basis

Provide medium composition, pressure, temperature, cycling, external conditions and mechanical loads. Obtain the selected material, coating, joint and rating evidence before acceptance. Low Pressure and Class 150 do not provide numerical service limits here; agree dimensional checks, examination/testing and supply documents rather than assuming the broad application list qualifies every use.
