This B16.5 A105 Class 300 carbon steel blind-flange enquiry needs confirmation of the offered closure. Actual variants say Flange, while both reviewed gallery images show central openings, one apparently threaded. Obtain the selected solid blind drawing and matching product evidence before treating the title as an actual closure specification.
Confirm the solid blind against the gallery and selection
Ask whether the offered item is a solid blind flange and how its product evidence maps to the selected variant. Do not silently relabel it as a bored or threaded flange from the photos. The broad flange family is supported despite the imported Elbow table name. Define closure thickness, outside diameter, bolt circle, hole count and hole diameter on the selected drawing. Explain each millimetre menu size rather than assuming a nominal size or hole measurement.
Qualify A105 and Class 300 for the selected flange
Choose Carbon Steel for this enquiry and request the complete A105 material specification, edition and traceable records. Stainless Steel and Alloy alternatives need separate materials. Agree the applicable B16.5 edition and selected dimensional, material and rating evidence. Class 300 is not a pressure value independent of material and temperature. Support Forged and the actual surface condition with production and inspection records.
Assess the mating face and complete closure joint
Specify the sealing face, finish, mating flange, gasket and bolting as a matched assembly. Clarify the Welding table entry through the actual installation drawing; it does not establish a weld connection for a blind closure. Generic Equal, Hexagon and mounting-hole fields cannot replace that drawing. Provide fluid, pressure, temperature, corrosion and end-closure loads for full joint assessment. Customized Size does not establish supplied dimensions; confirm solid closure before accepting the assembled boundary.
