Notes

  • All dimensions are in millimetres.
  • Outside diameter, bolt circle and drilling are common to all EN 1092-1 flange types of the same DN and PN.
  • Values are nominal, compiled from published copies of the standard; blank cells (—) are values not confirmed from the sources available. Verify against the current edition before design, purchase or fabrication.

Reference information compiled from the published standard for convenience. It does not replace the current edition of the governing standard, which takes precedence. Verify critical dimensions and properties before design, purchase or fabrication. Teshi Engineers & Sales Promoters (P) Ltd accepts no liability for errors or omissions.

FAQ

EN 1092-1 PN6 Flange dimensions: common questions

What are the dimensions of a DN100 PN6 flange?

A DN100 PN6 flange to EN 1092-1 has an outside diameter of 210 mm, a bolt circle of 170 mm and 4 holes of 18 mm for M16 bolts.

Is EN 1092-1 PN6 interchangeable with ASME B16.5?

No. EN 1092-1 flanges use metric bolt circles and bolts; they will not bolt to ASME B16.5 flanges without special drilling.

Does Teshi Group manufacture EN 1092-1 flanges?

Teshi Group manufactures steel flanges in India to EN 1092-1 drilling — weld neck, slip-on, plate and blind — in carbon, alloy, stainless, duplex and nickel-alloy grades, with EN 10204 3.1 certificates.
