EN 1092-1 flange series
EN 1092-1
Use the EN 1092-1 reference to start selection, then confirm flange type, PN, material and mating dimensions. Threaded options need the specified thread form as well as the nominal connection size.

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.
Specifications compiled from available product documents。Dimensions, performance and suitability are subject to confirmed drawings and ordering documents.
