Major changes against edition 2001: i. flanges PN 160, PN 250, PN 320 and PN 400 have been introduced; ii. further methods of manufacture have been introduced; iii. welding conditions, inspection and testing have been introduced; iv. flange facing height f1 changed back to former DN related dimensions; v. further collar types have been introduced; vi. materials have been updated; vii. new p/t-ratings are related to the flange material; viii. rings for tongue and groove flanges have been introduced; ix. the following flange types have been re-calculated according to the calculation method in EN 1591-1 with the basic rules as described in Annex E of this standard:  flanges type 11 for PN 2,5 to PN 400. Types 12 and 13 have been adjusted to the results for Type 11. As a result the thickness of some flanges above DN 500 had to be increased and the !wall thickness" had to be adjusted;  flanges type 05;  flanges type 01;  flanges type 02 with 32 resp. 33 up to DN 600 for PN 2,5 to PN 40;  flanges types 35, 36 and 37 for PN 10 to PN 40;  types 21 and 04 with 34 have not been re-calculated according to EN 1591-1.

Scope 

This European Standard for a single series of flanges specifies requirements for circular steel flanges in PN designations PN 2,5 to PN 400 and nominal sizes from DN 10 to DN 4000. This European Standard specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange jointing face surface finish, marking, materials, pressure/ temperature ratings and approximate flange masses. For the purpose of this European Standard, "flanges" include also lapped ends and collars. This European Standard applies to flanges manufactured in accordance with the methods described in Table 1. Non-gasketed pipe joints are outside the scope of this European Standard.

Table 6 specifies the flange types and collar types. Figures 1 and 2 show flange types and collar types with the relevant flange type numbers. Flanges shall be denoted with "flange type" and the "flange description". Collar components shall be denoted with collar type and the collar description. Figure 3 shows flange facing types, which may be used with the flanges or components shown in Figures 1 and 2. Flange facings shall be denoted with "type" and the relevant symbol. The range of DN, applicable to each flange type and collar and to each PN, shall be as given in Table 7, however not all dimensions are existing for each type.
