This custom industrial piping listing describes a polished weld neck flange with a stainless steel 304 title designation. A Stainless Steel and Weld Neck Flange combination is available in the catalog. Confirm its actual grade and selected drawing before treating the listing as a complete welding connection specification.
Select the applicable standard and mating geometry
Identify the required numbered standard and edition within the ANSI, JIS or DIN references. Choose the pressure class, nominal size and facing for the intended mating joint. These broad labels do not define one configuration or demonstrate interchangeable drilling and face dimensions.
Specify neck and hub geometry, bore, pipe wall match and welding end preparation. Confirm the bolt circle, hole count and hole diameter from the approved drawing. The table lists four half-inch holes, which should not be extended to every type or size within the shared 1/2–120 inch range.
Verify the stainless grade and polished finish
Request material records supporting grade 304, including the governing material specification, condition, chemistry and traceability. The actual option identifies generic Stainless Steel rather than a separately certified grade. Other available material categories and flange types do not establish equivalent performance for this selected weld neck design.
Agree the required finish and inspection criteria beyond Polished. That wording does not establish passivation, a numerical roughness or compatibility with every process fluid. Confirm the manufacturing and dimensional acceptance documents applicable to the custom configuration.
Define pipeline duty and custom supply acceptance
Provide the conveyed fluid, contaminants, pressure, temperature, cycles and loads. High-pressure wording gives no allowable numerical envelope. Review the flange, welding joint, gasket and bolting requirements for the actual service. Confirm availability of the selected combination, marking, inspection package, preservation, quantity and delivery timing against the final purchase specification.
