Grade identity
UNS S32750 / 2507 or UNS S32760 stated exactly as approved by the project
Alloy flanges and fittings
Super Duplex Pipe Fittings Manufacturer & Exporter
Raymond Tube Industries manufactures and supplies Super Duplex pipe fittings for seawater, offshore, desalination, marine, and chloride-critical piping requirements. Elbows, tees, reducers, caps, stub ends, and forged fitting enquiries should identify UNS S32750 / 2507, UNS S32760, or the exact approved grade, then define full geometry, NPS or DN, schedule or bore, end preparation, standards, heat treatment, testing, traceability, quantity, packing, and destination.
Technical snapshot
Key details for your specification.
Engineering discussion
Context before component selection.
Grade identity must survive every process step
State S32750 or S32760 on the line item and require heat or lot identity to remain connected through forming, heat treatment, tests, marking, packing, and final documentation.
Geometry and size sequence drive dimensional review
Elbow angle and radius, tee run and branch, reducer ends and orientation, stub-end pattern, schedule, bevel, and tangent details determine whether a fitting can be compared to the piping class and drawing.
Metallurgical testing is purchase-specific
The project may require heat-treatment evidence, phase balance, ferrite, hardness, corrosion testing, NDE, or NACE review. State the method, acceptance criteria, frequency, and witness point rather than assuming inclusion.
Forged fittings need their own line items
Socket-weld and threaded forms do not share the same dimensional or material route as wrought butt-weld fittings. Separate them by class, connection, size, grade, tests, and documentation.
Final release is a reconciliation exercise
MTC, test reports, dimensions, PMI, NDE, TPI release, marking, quantity, packing list, and destination labels should reconcile before dispatch authorization.
Standards and release
Define the basis, then document it.
ASTM A815 / ASME SA815
Common wrought super duplex fitting route; specify grade, class, construction, heat treatment, mechanical and corrosion requirements, and supplementary tests.
ASME B16.9
Applicable butt-weld fitting dimensions require complete geometry, size sequence, schedule or wall, radius, ends, and tolerances.
ASME B16.11
Forged socket-weld and threaded fittings require separate class, end, dimensional, material, and inspection definition.
Project test specification
Corrosion method, ferrite or phase balance, hardness, NDE, PMI, NACE review, sampling, and acceptance criteria must be stated where required.
