Review of Standards. To keep abreast of progress in industry, Joint Australian/NewZealand Standards are subject to periodic review and are kept up to date by the issue ofamendments or new editions as necessary. It is important therefore that Standards usersensure that they are in possession of the latest edition, and any amendments thereto.
Full details of all Joint Standards and related publications will be found in the StandardsAustralia and Standards New Zealand Catalogue of Publications; this information issupplemented each month by the magazines ‘The Australian Standard’ and ‘Standards NewZealand’, which subscribing members receive, and which give details of new publications,new editions and amendments, and of withdrawn Standards.
Suggestions for improvements to Joint Standards, addressed to the head office of eitherStandards Australia or Standards New Zealand, are welcomed. Notification of anyinaccuracy or ambiguity found in a Joint Australian/New Zealand Standard should be madewithout delay in order that the matter may be investigated and appropriate action taken.

PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee ME/1 onPressure Equipment. It is identical with and has been reproduced from ISO 7005-1:1992, Metallic flanges,Part 1: Steel flanges.
The objective of this Standard is to provide designers, manufacturers and users with an international Standardfor flanges for use in pressure applications.
This Joint Standard is one of the following series that applies to metallic flanges.
AS/NZS4331 Metallic flanges4331.1 Part 1: Steel flanges4331.2 Part 2: Cast iron flanges4331.3 Part 3: Copper alloy and composite flanges
Under arrangements made between Standards Australia, Standards New Zealand and ISO, users of thisStandard are advised that in Australia copyright is vested in Standards Australia and in New Zealandcopyright is vested in Standards New Zealand.
It is not intended this Standard be a mandatory replacement for any flange Standards already in use inAustralia or New Zealand. Before flanges to this Standard are used with flanges of other Standards,compatibility for bolting, strength, gasket seating and the like should be checked.
Statements expressed in mandatory terms in notes to text, tables and figures are deemed to be requirementsof this Standard.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of theannex to which they apply. A ‘normative’ annex is an integral part of a Standard, whereas an ‘informative’annex is only for information and guidance.
As this Standard is reproduced from an international Standard, the following applies:
(a) Its number appears on the cover and title page while the International Standard number appears only onthe cover.
(b) In the source text, ‘this International Standard’ should read ‘this Australia/New Zealand Standard’.
(c) A full point substitutes for a comma when referring to a decimal marker.
References to international Standards should be replaced by equivalent Australian Standards, as follows:

2.4.4.2 The hub dimensions of threaded (type 13) andslip-on (type 12) flanges having a reduced bore shall beat least as large as those of the standard flange of thesize to which the reduction is being made. For weldingneck (type 11) flanges having a reduced bore, the hubdimensions shall be the same as those of the standardflange of the size to which the reduction is being made.
2.4.5 Hubs — Pipeline applications
2.4.5.1 The hub diameter and wall thickness at thewelding end shall be determined as specified in 2.4.5.1.1to 2.4.5.1.3 as appropriate.
2.4.5.1.1 When the minimum yield strength of the hubportion of any flange or its representative test specimen isthe same as that of the mating pipe, the minimumthickness at the welding end shall be the same as that ofthe mating pipe.
2.4.5.1.2 When the minimum yield strength of the hubportion of any flange or its representative test specimen isless than that specified for the pipe to be matched, theminimum thickness of the hub at the welding end shall besuch that the product of its thickness times its yieldstrength (at the welding end) shall at least equal theproduct of the specified wall thickness and the minimumspecified yield strength of the pipe to be matched.

NOTE — Other welding end preparations agreed between manu-facturer and purchaser do not invalidate compliance with this partof ISO 7005.
2.5 Facings
2.5.1 Range of facings
The range of flange facings and flange face designationsshall be as given in figure 5. Dimensions of facings accor-ding to the PN designation shall be in accordance withfigures 6 and 7 and tables 4, 5, 6 and 7, as appropriate.
NOTES
1 For types B (as shown in figure 6 only), D, F, G and J thetransition from the raised face diameter to the flange face is atthe option of the manufacturer.
2 For PN 20 and PN 50 to PN 420 there are large and small ver-sions of C, D, E and F types of facing. In such cases two sets ofdimensions have been given in the related tables. For small maleand female joints care should be taken to ensure that the insidediameter of the pipe is small enough to permit sufficient bearingsurface.
3 The type B raised face on steel flanges may be removed whenbolted to cast iron or copper alloy flanges for designations up toand including PN 50 in order to provide full-face gasketing if suchbe required. On a flanged component or fitting this will reduce thethickness and the overall length accordingly.
2.5.2 Facing height/depth
For PN 2,5, PN 6, PN 10, PN 16, PN 25 and PN 40flanges all facing heights shall be included in the minimumflange thickness and are measured from the face of theflange. The same requirement applies for PN 20 andPN 50 flanges when they have the (type B1) raised face.For PN 20, PN 50, PN 110, PN 150, PN 260 and PN 420flanges with other facings, e.g. type B2, spigot and recess,tongue and groove, the height or depth shall be added tothe minimum flange thickness. For PN 110 to PN 420flanges all facings shall be added to the minimum flangethickness. Special requirements apply to ring-joint facings(see 2.5.3).
2.5.3 Ring-joint facings
The bottom of the ring-joint groove shall not encroachbelow the plane of the flange edge of the appropriateminimum thickness flange. Where the depth of the ring-type joint groove would violate this requirement, sufficientmetal shall be added to the flange thickness or raised faceheight so that the bottom of the groove shall be in thesame plane as the flange edge of a minimum thicknessflange.
2.5.4 Lapped joints
For type 33 ancillary components for flanges, the finishedheight of the facing shall be not less than the pipethickness used. If a tongue, groove or ring-joint face isrequired, the thickness of the lap remaining aftermachining the facing shall not be less than the specifiedthickness of the pipe used.
2.5.5 Surface finish of flanges
2.5.5.1 All flange jointing faces shall be finished inaccordance with table 1 or table 2, as appropriate. Thesurface finishes of the faces shall be compared by visualor tactile means with reference specimens which conformto the Ra and Rz values given in tables 1 and 2.

1) Large spigot and recess faces and large tongue and groove are not applicable to PN 20 because of potential dimensionalconflicts.
2) f1 applies to PN 20 and PN 50, and is included in the minimum flange thickness.
3) f2 applies to PN 110, PN 150, PN 260 and PN 420, and is addit ional to the minimum flange thickness.
NOTE — For small spigot and recess joints care should be taken in the use of these dimensions to ensure that the insidediameter of the fit ting or pipe is small enough to ensure suff icient bearing surfaces.

1 For tolerances, see 2.7 and section 4.
2 For facings, see 2.5, figure 6 and table 4.
3 For spot-facing, see 2.6.
4 For reducing threaded, slip-on and weld neck flanges,see 2.4.4.2.
5 For threads in threaded flanges, see 2.4.3.
6 The neck thickness dimension S is applicable to themajori ty of flanges, but for sizes above DN 600 or for flangesto be used with other pipe wall thicknesses, the neckthickness is subject to agreement between the manufacturerand purchaser.
7 The neck diameter N 3 is the theoretical maximum whichwill permit the use of ISO ring spanners or the fi tt ing, ifrequired, of the normal series of ISO washers (ISO 887)without some form of additional machining such as spot-facing(see 2.6). The washer, if used, may theoretically overlapslightly the corner radius but in practice it is deemed thatthere is suff icient space to fi t the washer satisfactorily.
8 The bore diameter B in sizes generally above DN 600should be specif ied by the purchaser.
The bore for a welding neck (type 11) or a socket weld(type 14) flange should be specified by the purchaser ifrequired to dif fer from the dimensions given in tables 8 to 11,13 and 14.
9 In respect of threaded flanges, the outside diameters ofDN 65, DN 125 and DN 150 pipes should be as shown in thefollowing table.

10 Up to and including nominal size DN 600, the flangeshave been recalculated recently according to the relevantGerman (DIN) calculation method. For this reason it wasnecessary to increase certain flange thicknesses. Abovenominal size DN 600, flange thicknesses remain as they were,but the previous pressure/temperature ratings are no longerapplicable (see E.1).
Notes to tables 12, 15, 16, 17, 18 and 19
1 For tolerances, see 2.7 and section 4.
2 For facings, see 2.5, figure 7 and tables 5, 6 and 7.
3 For spot-facing, see 2.6.
4 For reducing threaded, slip-on and weld neck flanges,see 2.4.4.2.
5 For threads in threaded flanges, see 2.4.3.
6 Blank flanges may be with or without hubs at themanufacturer’s option.
7 For welding of unequal wall thicknesses, see theacceptable bevel designs in annex B.
8 Dimensions for B3 correspond to the inside diameter ofthe pipe as given in ANSI/ASME B36.10 for Standard Wallpipe. The thickness of Standard Wall is the same as Schedule40 in sizes DN 250 and smaller. Tolerances in table 20 apply.
9 When PN 20 and PN 50 flanges are required with flatface, either the full thickness or the thickness with the raisedface removed may be furnished. Users are reminded thatremoving the raised face wil l make the length through the hubnon-standard. See 2.5.2.
10 The bore for a welding neck (type 11) or a socket weld(type 14) flange should be specif ied by the purchaser ifrequired to differ from the dimensions given in tables 12 and15 to 19.
11 In respect of threaded flanges, the outside diameters ofDN 65, DN 125 and DN 150 pipes should be as shown in thefollowing table.

Guidance on flange materials
D.1 General
When work started on this part of ISO 7005 it wasdecided to refer to the German and American steelswhich were used for the manufacture of the Europeanand American steel flanges on which this part ofISO 7005 is based. Since then a number ofISO standards have been published, or are in pre-paration, which specify steels suitable for themanufacture of flanges. However, the complete suite ofISO standards has yet to be published, and thereforethe materials specified in this annex are given forguidance only and users are entitled to select othersteels from national standards in preference, asdeemed necessary. Moreover, if specifying steels notgiven in this part of ISO 7005, users of this part ofISO 7005 have the responsibility to ensure that thesteels are suitable for the PN designations given. In afuture edition of this part of ISO 7005, steels fromISO standards only will be specified.
Guidance on pressure/temperature ratings for certainflanges made from the materials given in this annex isgiven in annex E.
D.2 Range of materials
Except for pipeline flanges, flanges specified in thispart of ISO 7005 may be manufactured from materialsselected from tables D.1 and D.2.
NOTE — See also 1.1.
When PN 20, PN 50, PN 110 and PN 150 flanges arespecified for pipeline applications, materials may beselected from table D.3.
D.3 Material groupings
Materials in this part of ISO 7005 are identified by abasic material reference.
NOTES
1 Several materials have been placed in any one group withthe provision that they give a compatible rating for the flangedjoint i.e. materials likely to be used together are capable ofmaintaining the same rating). In this respect the charac-teristics of any material in a given group are compatible withthe rating for that group. Consequently, ratings for somematerials are conservative (see also annex E).
2 The specif ications may not be equivalent in all details andtherefore may not be equally suitable for all applications.
D.4 Materials for PN 20, PN 50, PN 110 andPN 150 flanges types 05 and 11 for nominalsizes DN 300 and larger for pipelineapplicationsThe steel used in the manufacture of PN 20, PN 50,PN 110 and PN 150 flanges types 05 and 11 fornominal sizes DN 300 and larger for pipelineapplications given in table D.3 should be selected bythe manufacturer to meet the following recommen-dations.
D.4.1 The 4.A.330 and higher grades of steel forPN 110 and PN 150 flanges should be killed steel.
D.4.2 The steel used should be suitable for fieldwelding to other flanges, fittings or pipe manufacturedto the appropriate International Standards.
D.4.3 The steel used should have a maximum carboncontent of 0,35 % (m/m) and a carbon equivalent (C.E.)computed using the following equation:
which should not exceed 0,50, based on checkanalysis. If the carbon equivalent exceeds 0,50, theacceptance of the flanges should be based on agree-ment between the purchaser and the manufacturer.
The choice and use of alloying elements, combinedwith the elements within the limits given above to givethe required tensile properties prescribed in D.4.4,should be made by the flange manufacturer andincluded and reported in the ladle or check analyses toidentify the type of steel.
D.4.4 The steel used should have tensile propertiesconforming to the requirements given in table D.3 andbe capable of meeting the flange manufacturer’s designconditions as given in annex F.
The test specimens should be taken from the forgingsor, at the manufacturer’s option, from the billets orforging bars used to manufacture the finished product,provided that such a test specimen has undergonesubstantially the same forming and the equivalent heattreatment as the finished flange. The dimensions of thetest specimen should be such as to reflect adequately

the heat treatment properties of the hub of the flange.Specimens should be obtained from the midwall of thethinnest section of the hub of the flange or 19 mm fromthe surface of the test specimen. The orientation ofspecimens taken from a flange should be longitudinal.If a separate test bar is used, it should be heat treatedin a heat treat batch with the flanges it represents.
D.4.5 The 4.A.290 and higher grades of steel forPN 20, PN 50, PN 110 and PN 150 flanges and the4.A.250 grade of steel for PN 110 and PN 150 flangesshould be normalized or quenched and tempered.
NOTE — It is recognized that the cooling rate in a quenchingoperation may be slower in the thicker ring section of theflange than in the thinner hub section. Hence, the increase inyield strength due to the quenching operations may be less inthe ring section than in the hub section. This factor isaccounted for in D.4.6.
D.4.6 The flange ring should have sufficient pressurecapacity for the service based on its strength in thenormalized condition. This capacity should be substan-tiated by design calculations using the allowable designstresses as given in annex F of this part of ISO 7005.

Annex E(informative)
Guidance on pressure/temperature ratingsE.1 General
The pressure/temperature ratings given in this annexapply only to certain flanges made using the materialslisted in annex D.
Where given, the pressure/temperature ratings of thematerials specified are maximum allowable non-shockworking pressures (expressed as gauge pressure inbar) at the temperatures given in the respective tablesfor the applicable material. Linear interpolation ispermitted for intermediate temperatures.
The ratings of the flange materials are given in thefollowing tables.
Tables E.1 to E.4 — Pressure/temperature ratings forPN 2,5, PN 6, PN 10, PN 16, PN 25 and PN 40 for thematerial groups given in table D.1 and valid only forflanges of types 05, 11, 12, 13 and 21 in nominal sizesup to and including DN 600.
For all flanges of types 01, 02, 03 and 04 and for types05, 11, 12, 13 and 21 having nominal sizes greaterthan DN 600, pressure/temperature ratings applied arethe responsibility of the user.
For austenitic stainless steels, pressure/temperatureratings are based on a reference stress of 205 N/mm2
for the 0,2 % proof stress and a reference stress of225 N/mm2 for the 1% proof stress, the rating beinggiven in tables E.3 and E.4 respectively. Two tables ofpressure/temperature ratings for austenitic stainlesssteels are given because some codes of practice forthe design of flanged equipment use the 0,2% proofstress value and others use the 1% proof stress value.
Tables E.5 to E.21 — Pressure/temperature ratings forPN 20, PN 50, PN 110, PN 150, PN 260 and PN 420for the material groups given in table D.2. The ratingsare in accordance with the standard ratings forflanged and butt weld end fittings specified inANSI/ASME B16.5.
Table E.22 — Pressure/temperature ratings for PN 20,PN 50, PN 110 and PN 150 for the material groupsgiven in table D.3 for use in pipeline applications in thesize range DN 300 and larger for types 05 and 11 only.
NOTE — There is not yet in existence a common interna-tionally accepted procedure to evaluate pressure/temperatureratings for flanges. Before introducing tables E.1 to E.22 intonational standards, it should be checked whether they complywith the relevant national codes and regulations.
E.2 Rating of flanged joints
If two flanges in a flanged joint do not have the samepressure/temperature rating, the rating of the joint atany temperature should not exceed the lower of the twoflange ratings at that temperature.
NOTES
1 The temperatureshown for a corresponding pressure ratingis considered to be that of the contained fluid. The use of apressure rating corresponding to a temperatureother than thatof the contained fluid is the responsibili ty of the user and issubject to the requirements of any applicable code orregulation.
2 Application of the ratings in this part of ISO 7005 to flangedjoints should take into consideration the risk of leakage dueto forces and moments developed in the connecting pipework.
3 At temperatures in the creep range, gradual relaxation offlanged joints may progressively reduce bolt loads and thetightness of the joint.
4 At low temperatures some of the materials listed in therating tables undergo a suff icient decrease in impactresistance that they cannot safely sustain sudden changes instress or temperature.
5 Owing to the nature of any thread sealant used, addit ionallimitations may be placed on a threaded flange.
6 These notes on service conditions are not intended to beexhaustive.

Design criteria (pipeline applications)
F.1 For PN 50, PN 110 and PN 150 flanges, the slopeand the outside diameter of the hub at the base aredesigned for welding ends having the same yieldstrength and thickness as those of the mating pipe. Thewall thickness of the intended mating pipe was basedon API 5LX-52 with a 0,68 design factor for the DN 650to DN 900 sizes, and API 5LX-65 with a 0,72 designfactor for the DN 950 to DN 1 500 sizes. When themanufacturer of the DN 650 to DN 900 sizes elects toutilize the alternative permitted in 2.4.5.1.2 or when themating pipe has a minimum specified yield strengthexceeding 448 N/mm2, it will be necessary torecalculate the design in accordance with therequirements of 2.4.5.1.2.
F.2 The design of the DN 950 and larger sizes of thePN 50 and higher class of welding neck flanges is
based on the flange material having a minimumspecified yield strength of at least 290 N/mm2 in a ringsection of the flange and a minimum yield strength atthe welding end at least equal to that specified for themating pipe. When the yield strength of the welding endof the flange is less than specified, compensation inaccordance with 2.4.5.1.2 may be made, but the hubslope and diameter at the larger end have to bepreserved.
F.3 The design of all sizes is based on the use ofheat-treated carbon steel bolt studs for PN 20 flangesand alloy steel bolt studs for PN 50, PN 110 andPN 150 flanges.
