This UNI 2276 PN6 one-inch bolted plate flange enquiry carries Puhui Industry and ASTM A350 LF2 naming. Establish a single accepted dimensional, material and rating specification before selecting the component. The quotation should identify the actual flange construction and the parts included in the assembly.

Agree the UNI and PN6 specification

Confirm the intended UNI 2276 edition and its applicable type, material, size and rating scope. PN6 and Class 150 must not be treated as equivalent selections or combined into a certified rating. Define the pressure-temperature acceptance basis for the material being supplied; low-pressure terminology provides no numerical operating envelope.

Request the selected one-inch drawing with flange thickness, outside diameter, bore, facing, bolt circle, hole count, hole diameters and tolerances. A size choice of None does not select that interface. Repeated inch ranges for other dimensions cannot complete the drawing or certify plate-flange geometry.

Confirm the plate body and pipe attachment

Identify the delivered material specification and any separate backing or support components. Polypropylene and PP choices need a confirmed material designation and supply scope. A350 LF2 naming does not independently certify the delivered material. Request the appropriate product condition, manufacturing route and inspection traceability.

Specify the actual pipe-side attachment separately from the bolted mating joint. Any NPT or BSPT requirement needs its own end dimensions and acceptance checks. Agree the polished finish as a surface requirement without inferring corrosion resistance or sealing capability from appearance.

Document provenance and project acceptance

Use Puhui Industry as an enquiry reference and request provenance documents when manufacturer identity matters. Provide the fluid, pressure, temperature, cycling and imposed loads for the intended service. Review mating parts, gasket, fasteners, support and assembly as a complete joint. Confirm PPF-PH applicability, requested customization and the stated three-year warranty terms in the quotation.
