This stainless blind-flange enquiry references the grades 304/316, carbon steel bolts and pressure-temperature ratings. Its actual variants identify generic Flange choices without a blind subtype, exact grade or supplied bolt package. Confirm the closure and hardware scope before treating these title references as an accepted joint specification.
Confirm the closure separately from bored gallery examples
The photographs include bored and hubbed flanges as well as an open-centre/closed-centre pair. They do not establish every variant as blind. Obtain the selected drawing with the actual closure thickness, outside diameter, bolt circle, hole details and facing. The table's Welding label does not justify assuming a pipe opening in a blind design. If the selected flange is bored instead, clarify its pipe attachment separately.
Specify the carbon steel bolting and supply scope
Ask whether bolts are included or only referenced as a companion requirement. Identify the exact bolt or stud and nut grades, dimensions, threads, coating and assembly requirements; no particular grades are assigned by the page. Assess them with the mating flange and gasket for the intended material, temperature and corrosion conditions. Generic carbon steel wording does not establish compatibility or a complete supplied bundle.
Build the rating assessment from the selected materials
Choose one exact stainless grade with complete specifications and traceability; 304 and 316 are not automatically equivalent or jointly qualified. Alloy and Carbon Steel flange alternatives require separate assessment. Explain the millimetre size convention and complete the face and dimensional drawing beyond the generic table fields. Verify Forged and the required finish beyond Smooth. Pipe Class 900 needs its standard, unit and material/temperature basis. Supply fluid, pressure, temperature, corrosion and mechanical loads for the closure and entire bolted joint.
