Metal flange series
METAL FLANGE SERIES
Metal flanges cover several material families and connection forms. Start with the service requirements, then confirm a complete standard, grade, size and facing specification for the intended mating connection.
- Material families — separate options
- Carbon steel; stainless steel; alloy steel. Exact grade and product form TBC.
- Standard families — separate options
- ANSI/ASME; DIN; BS; JIS; UNI; EN 1092-1. Select one exact standard and edition.
- PN designations listed
- PN6 / PN10 / PN16 / PN25 / PN40
- Class designations listed
- Class 150 / 300 / 400 / 600 / 900 — alternatives, not working pressure in psi.
- Structure options listed
- Slip-on, weld neck, blind, lap joint, socket weld, threaded, plate, loose, SOP and SOH (A/B/C); applicable type standard TBC.
- Facing designations confirmed in the text
- RF / FF; the additional source token RT is unconfirmed.
- Ordered size and drilling
- TBC — no size-by-size dimensional table is published on this product page.
- Pressure–temperature rating
- TBC for the selected material, standard, size and operating temperature.
Confirm configuration, price, quantity and lead time for each enquiry.
Selection questions
What should I include in a flange enquiry?
Provide standard and edition, size, material specification and grade, type, pressure designation, facing, quantity, and design pressure/temperature. Include a mating drawing when drilling or bore dimensions are critical.
Does the pressure designation equal the working pressure?
No single operating-pressure value follows from PN or Class alone. Confirm the applicable pressure–temperature rating for the selected standard, material and temperature.
Can flanges of the same nominal size be connected directly?
Check the exact standard, bolt-hole count and diameter, bolt circle, bore, facing and gasket arrangement. A matching size label alone does not establish interchangeability.
