Confirm the supplied material before ordering this 48-inch RF Q235A carbon steel polished blind-flange enquiry. The title describes steel, but both actual variants list Polypropylene or PP with size None. These records conflict; neither the title nor the option labels alone establishes the delivered material.

Identify the actual closed flange and requested size

The reference image shows bright closed-center flange forms with bolt holes. It cannot certify alloy, grade, scale or facing geometry. Ask for the individual component identity and clarify what 48-inch describes. Size None and the table’s smaller one-eighth-to6-inch entries do not confirm that individual supply.

Obtain an approved drawing with outside diameter, thickness, closed-center construction, facing dimensions/finish, bolt circle, hole count/diameter and tolerances. Allocate the RF reference to the actual mating face. Clarify generic Equal and NPT OR BSPT fields without assuming threaded closure features.

Resolve grade, manufacturing and class documentation

The ASTM title reference is incomplete. Specify the governing material and dimensional/class documents, editions, full grade, condition and traceability. Q235A wording requires accepted material records, and the table’s Mould entry does not establish how the pictured component was manufactured.

Pipe Class150 is an unallocated table entry, while Low Pressure is qualitative. Obtain the selected material/document/temperature basis and accepted numerical duty. Agree polished surfaces and inspection criteria without inferring corrosion performance from the bright photograph or Polishing wording.

Accept the complete bolted closure for its project

State medium, pressure, temperature, cycling and loads; confirm material, gasket and bolting compatibility. Listed water, fire-protection, gas and petroleum contexts require actual project approval. Agree installation/inspection, marking, material/manufacturing/dimensional documents, individual-size availability, quotation scope and three-year warranty/customization terms.
