This carbon steel end cap is listed for construction and gas enquiries with a B16.9 title reference. The record needs clarification of both size and connection wording. Confirm the actual component drawing before accepting the title as a complete dimensional or joining specification.

Resolve the DN100 description and metric variant

The title says DN100, while the only variant is Cap / 10 mm / Carbon Steel. Request one consistent nominal size and the meaning of the metric label. These entries do not establish the selected cap dimensions or justify choosing one size without supplier confirmation.

Flange and Butter Weld occur together in the title, with Flange connectivity in the table. Ask for an explicit end-interface designation; the ambiguous wording should not be silently converted into a verified butt-weld connection. Obtain applicable mating, face, drilling, sealing or end-preparation details for the agreed design.

Allocate geometry and verify the material supply

Request outside dimensions, wall and tolerances, and locate the four-inch length, quarter-inch mounting hole, round shape and hexagon head on the drawing. The inch measurement system does not reconcile the size discrepancy. Identify the exact carbon steel grade and condition plus governing B16.9 documents, editions and selected component scope.

Obtain material certificates, traceability and manufacturing records supporting the machining entry. Painting needs a coating system, preparation, thickness and inspection criteria. Corrosion, chemical, UV, flexible and underground labels require relevant evidence rather than automatic performance acceptance.

Specify the construction and gas-service conditions

Provide gas composition, pressure, temperature, cycling, external exposure and construction loads. Require the selected material, coating, joint and rating basis and agree examination/testing and documentary acceptance. Neither Low Pressure nor Class 150 supplies numerical operating limits here; the wider industry list does not certify the cap for every application.
