This stainless steel flange enquiry includes PN16, PN20 and Class 150 title references. The actual variant names Socket Weld Flange, but the gallery does not establish its internal socket detail. Confirm the selected flange through a sectional drawing before using the subtype, pressure labels or photographs to specify a joint.

Verify the socket configuration and one selected size

Request a section showing socket recess, bore, pipe engagement and welding detail. Match it to one nominal size and the actual adjoining pipe. The half-inch to twenty-four-inch option describes a range-like label, not selected dimensions or proven supply capacity. Record flange diameter, thickness, hub dimensions, bolt circle and hole count/diameter. The necked or hubbed shapes in the photos cannot establish these measurements.

Assign one standard and pressure designation

Specify the numbered document and edition behind the DIN ANSI JIS entry. Clarify whether the requirement is PN16, PN20 or Class 150, and obtain its basis for the chosen size, material and standard. Do not treat these labels as equivalent or as verified multiple ratings. Ask for clarification of the malformed pressure string in the table without silently interpreting its merged numbers. Agree the actual stainless grade and traceable material evidence separately.

Check the sealing face and completed flange joint

Confirm whether FF describes the selected sealing face despite appearing under Surface Treatment. Define its mating face, finish, gasket and bolting, together with socket welding and inspection requirements. Clarify actual coating and sealing-surface condition beyond Silver and Blank Paint. Casting Test wording requires production records and test scope/results before it can support acceptance. Supply fluid, pressure, temperature, corrosion and mechanical loads for complete joint assessment; the industry list does not qualify a particular service.
