Clarify the material-class notation before specifying this 3-inch A350 LF2 Cl3 B16.5 carbon steel blind-flange enquiry. The title’s grade reference needs documentary allocation, and actual variants list Polypropylene or PP. Confirm the supplied identity rather than accepting either conflicting material record as certified.

Separate material class from flange Class 150

Request the governing material document and edition, full grade/class notation, condition, traceability and accepted certificates. Do not silently revise A350 LF2 Cl3 wording or infer low-temperature capability from the title. Material class and flange Class 150 need their own documented acceptance.

Identify the B16.5 edition and applicable selected material/size/class provisions. Low Pressure is qualitative, and Class 150 does not directly establish numerical operating duty. Obtain the accepted material/document/temperature basis for the actual closure and complete bolted joint.

Confirm the individual three-inch drawing and supply

Both variants use size None. Establish what the title’s three-inch reference identifies and confirm individual availability. The table’s repeated one-eighth-to6-inch entries do not establish actual overall or bolt-hole dimensions. Require outside diameter, thickness, closure configuration, facing dimensions/finish, bolt circle, hole count/diameter and tolerances.

Specify the actual facing instead of assuming an unlisted RF configuration. Clarify Equal and NPT OR BSPT fields against the drawing. Obtain production evidence for Mould, and agree the surfaces and inspection criteria covered by Polishing without inferred corrosion or hygiene performance.

Accept the closure for defined operating conditions

Provide medium, pressure, temperature, cycling, external loads and compatibility requirements. Listed water, fire-protection, gas and petroleum uses need project approval. Agree gasket, fasteners, installation/inspection, material/manufacturing/dimensional/class documents, marking, supply confirmation, quotation scope and three-year warranty/customization terms.
