Principal grades
UNS S32750 / 2507 and UNS S32760 as distinct project-approved material routes
Alloy flanges and fittings
Super Duplex Flanges Manufacturer & Exporter
Raymond Tube Industries manufactures and supplies Super Duplex Stainless Steel flanges for seawater, offshore, subsea, desalination, marine, chemical, and other chloride-critical project requirements. State UNS S32750 / 2507, UNS S32760, or the exact approved grade together with flange form, size, class, facing, bore, material and dimensional standards, metallurgical testing, inspection, documentation, packing, and destination.
Technical snapshot
Key details for your specification.
Engineering discussion
Context before component selection.
S32750 and S32760 need separate grade control
Super duplex is not a sufficient order description. State the exact UNS and project grade, then reconcile it with the material standard, heat treatment, tests, and piping class. Grade substitution requires documented engineering approval.
Pressure-joint geometry must be explicit
For WNRF, WNRTJ, blind, slip-on, long weld neck, or drawing-based flanges, state class, facing, bore, gasket system, surface finish, hub or neck details, and any RTJ inspection requirement.
Metallurgical evidence is part of the specification
Define any required ferrite or phase-balance evidence, hardness, corrosion testing, heat-treatment record, NDE, and sampling plan before manufacture. Acceptance comes from the agreed records, not from generic marketing language.
TPI needs an inspection sequence
Identify document review, material verification, hold or witness points, dimensions, PMI, NDE, corrosion tests, marking, packing, and final release so the inspection agency can follow an approved plan.
Service inputs protect material-selection decisions
Provide chloride level, temperature, pressure, fluid, sour conditions, crevice exposure, fabrication restrictions, and cleaning chemistry where relevant to engineering review and test scope.
Standards and release
Define the basis, then document it.
ASTM A182 / ASME SA182
Confirm the exact super duplex grade, heat treatment, mechanical requirements, tests, and project supplementary requirements for forged flanges.
ASME B16.5
Common dimensional basis for applicable flange sizes and pressure classes, used with the piping class and material specification.
ASME B16.47 / B16.36
Apply only where large-diameter or orifice-flange scope is relevant and the project has identified the correct series or configuration.
NACE and corrosion tests
Sour-service and corrosion-test acceptance are project-specific; state the governing requirement, method, acceptance criteria, and report scope.
Applications and next steps
