This DN200/eight-inch PN10 backing-ring flange enquiry requires a defined support arrangement. Clarify how the stainless-steel and S235JR title references apply to individual supplied components. Neither the name nor the reference colors establish a certified material, coating or independent sealing capability.
Match the title size to the supplied assembly
The fifteen actual Flange alternatives pair 10 mm, 12 mm, 14 mm, 50 mm and 30 mm labels with Stainless Steel, Alloy or Carbon Steel. Their nominal or measured roles must be confirmed. Do not assume equivalence to DN200/eight-inch naming or availability of that title size from these labels.
Prepare a component schedule identifying the backing ring, supporting pipe-end component and any additional supplied parts. Assign exact material designation, grade, condition and traceability separately. The S235JR reference requires its applicable document and component assignment rather than automatic certification of every material alternative.
Specify the support contact and attachment scope
Define inside/outside diameter, thickness, support/contact geometry, bolt circle, hole quantity and diameters, associated component interfaces and tolerances. The separate 0.25-inch mounting-hole value does not establish complete drilling. Customized Size and Equal/Hexagon wording require drawing-based acceptance.
The images show a yellow-toned drilled ring and a dark open-bore component with annular face lines. They cannot establish supplied subtype or finish. Identify where any Welding requirement applies; do not assume a direct weld on the backing ring. Agree the actual mating, sealing/gasket and bolting arrangement.
Accept documented production and operating limits
Obtain relevant forged-production records and painting scope with functional-surface exclusions. Establish the governing material-temperature basis for PN10 and Class 1000. State medium, pressure, temperature, cycling and loads; agree assembly, installation, inspection, OEM/ODM/OBM deliverables and stated one-year warranty terms.
