DIN flange series
DIN FLANGE SERIES
This series groups the DIN flange forms listed in the catalogue. Specify the exact DIN reference, nominal diameter, PN designation and material; historical standard numbers require an agreed edition and applicable drawing.
- Standards named in the product introduction
- DIN 2631, 2632, 2633, 2634, 2635, 2576, 2502, 2566, 86029, 86030, 2527; editions/applicability TBC.
- Material families — separate options
- Carbon steel; stainless steel; alloy steel. Exact grade and product form TBC.
- PN designations listed
- PN2.5 / PN6 / PN10 / PN16 / PN25 / PN40 — exact standard/type pairing TBC.
- 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.
