Note:

-Flanges > DN 2000, are not covered in this summary.

-Dimensions: Nominal sizes, DN followed by a numerical designation of size (a convenient round number for reference purposes), are used as defined in ISO 6708.

-Pressure Ratings: Nominal pressures, i.e. PN followed by a numerical designation of size (a convenient round number for reference purposes), are used as defined in ISO 7268.

1 Dimensions for these flanges are not covered in this summary.

2 The DN range for weld neck flanges extends to DN 4000 for PN 2.5, to DN 3600 for PN 6, and to DN 3000 for PN 10.

Designations/Marking

Marking. All flanges are marked with BS number, code number,PN,DN,material designation,manufacturers name or trade mark,cast number or melt identification,thread identification,An example follows:

BS 4504/111/B – PN 16 -DN 400 -B4 – XXX – 12345.

BS-4504-FLANGE-MARKING-REQUIREMENT

Cast Number or melt identification Manufacturer’s name or trade mark Material designation Nominal size, DN

Nominal Pressure, PN Flange face type (A – H) Flange code number British standard number

 

Our products like flanges are packaged to make sure that there’s no damage throughout transit. Just in case of exports, customary export packaging is completed in wooden boxes or cases. All flanges are marked with Trademark (Company’s LOGO), Grade, Size and Lot No. On requests we can do custom marking on our products.
