Specifies international requirements for circular grey, malleable and ductile cast iron flanges in nominal pressure designations, PN 2.5 to PN 50. Types of flanges, their facings, dimensions, tolerances, bolt sizes, surface finish of faces, marking, testing, inspection and materials together with associated pressure/temperature ratings are specifed. This Standard is identical with and has been reproduced from ISO 7005-2:1988.

Scope

This part of ISO 7005 for a single system of flanges specifies requirements for circular grey, malleable and ductile cast iron flanges in the following nominal pressure ratings:
Series 1* Series 2*
ISO PN10 ISO PN2,5
ISO PN16 ISO PN6
ISO PN20 ISO PN25
ISO PN50 ISO PN40
This part of ISO 7005 specifies the types of flanges and their facings, dimensions, bolt sizes, surface finish of faces, marking, testing, inspection and materials together with associated pressure/temperature ratings.
NOTES
1 Attention is drawn to the need to refer to the pressure/ temperature rating tables for the permissible working pressures, particularly for flanges of ISO PN20 and ISO PN50.
2 Dimensions of gaskets will be the subject of a future International Standard.
