Type, class & facing
State weld neck, slip-on, blind or other required type; NPS / DN; dimensional standard and edition; class / PN; RF, FF, RTJ or matched special facing. Confirm the permitted type/material combination against the governing code.

Inconel / Alloy 601 Flanges
Heat-resistant nickel-alloy enquiry; oxidation performance alone does not define allowable flange pressure.
Exact material / forging specification and condition to confirm
Build this grade enquiry ↓What makes this enquiry different?
Confirm exact forging specification, product availability and design-temperature basis.
This is a grade-specific enquiry reference. It does not establish current stock, manufacturer approval, every size/class combination or suitability for a particular process.
Bore & manufacturing route
Define bore or pipe schedule / actual wall, hub and weld-end requirements, facing finish, tolerances and drawing revision. Identify whether a forging is mandatory; plate or bar material identification alone does not establish flange compliance.
Testing & certification
Agree material condition, MTC type, heat traceability, chemical/mechanical records, PMI / NDT and supplementary tests. Define TPI witnessing and acceptance criteria before ordering.
Service & delivery
Provide fluid chemistry, design pressure and temperature, project piping class and approved manufacturer restrictions. Add quantity, units, destination, required date, packing, origin records and commercial delivery scope.
Dimension references

Does the grade establish a working-pressure rating?
No. The governing dimensional/rating standard, permitted material group, temperature, component geometry, mating joint and engineering specification must be checked. Class numbers are not universal pressure values.
Can the offered material be substituted?
Any change in alloy, product specification, material condition or construction requires project review and written approval before supply.
