FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by theChemical Engineering Plants and Related Equipments Sectional Committee had been approved by theHeavy Mechanical Engineering Division Council.This standard is being prepared in two parts. Part 2 of this standard shall cover the materials ofconstruction dimensions of gaskets and other design considerations.In this standard, flanges of all ratings, flanged fittings of all ratings and flanged fittings ( base type ) ofall ratings are grouped together for basic convenience to user.The pipe size designations and dimensions are given in Annex A.In the formulation of this standard, assistance has been derived from:
a) ANSI B 16.5-1981 ‘Pipe flanges and flanged fittings’, issued by the American NationalStandards Institute;
b) IS0 2229 ‘Equipment for the petroleum and natural gas industries - Steel pipe flangesnominal size I /2 to 24 in - Metric dimensions’ issued by the International Organization forStandardization ( IS0 );
c) MSS SP-25 3tandard marking systems for valve fittings, flanges and unios’ issued by theManufacturer’s Standardization Society of the Valve and Fittings Industry Inc. USA; and
d) MSS SP-9 ‘Spot facings for bronze, iron and steel flanges’, issued by the Manufacturer’sStandardization Society of the Valve and Fittings Industry Inc. USA.
Till such time the Part 2 of the standard is available the material designations in Table B 2 to B 8 aregiven as per ANSI system for guidance and easy implementation of the standard.
For the purpose of deciding whether a particular requirement of this standard is complied with, thefinal value, observed or calculated, expressing the result of a test or analysis, shall be rounded off inaccordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised )‘. The number ofsignificant places retained in the rounded off value should be the same as that of the specified value iathis standard.

FITTINGS-SPECIFICATION
PART 1 DIMENSIONS
1 SCOPE
This standard covers dimensions, tolerances, mark-ing, testing and methods of designating openingsfor pipe flanges and tlanged fittings in sizes DN15to DN600. Flanges and flanged fittings may be castor forged. Blind flanges and reducing flanges with-out hubs may also be made from plate. Pressure-temperature ratings tables are given in Annex B forvarious materials. The ratings are applicable fortype and form of fittings as mentioned above.
A flange or flanged fitting used under the IndianBoiler Regulation will be subjected to any/all lim-itations of that regulation. This includes any maxi-mum temperature limitation, rule governing theuse of a material at low temperature or provisionsfor operation at a pressure exceeding pressure tem-perature ratings given in this standard.

For tolerances, see 9 to 9.10.
For facings, src? 6.8.
For flange bolt holes, see 7.4 and corresponding flange tables.
For spot facing, see 7.5.
These dimensions are for large end of hub, which may be straight or tapered. Taper shall not exceed 7”on threaded, slip-onthreaded, slip-on, socket welding and lapped flanges.
For reducing threaded and slip-on flanges, see Table 8. .
For threads in threaded flanges, see 7.8 to 7.8.4.
Blind flanges may be made with or without hubs at the manufacturer’s option.
For welding end bevel, see 7.6.
For reducing welding neck flanges, see 7.7.
Dimensions in col 12 of Table 1 to 6 and col 11 of Table 7 tortes nd lo inside diameters of standard wall pipe. Thickness ofstandard wall is the same as SCH 40 (see Annex A) in sizes DN 2 0 and smaller.Tolerancc in 9.5 shall apply.!?
The minimum thickness of these loose flan8.
es, in various flange tables, in sizes DN 90 (NPS 3’12) and smaller is slightly greaterthan the thickness of flanges on fittings, w tch are reinforced by being cast integral with the body of the fitting.
When these flanges are required with flat face, either the full thickness or thickness with raised face removed may be furnished.Users are reminded that removing the raised face will make the length through the hub non-standard.
5.5 Size 6.3 Face to Face/End Dimensions
The nominal diameter shall be given, but may beomitted from reducing flanges and reducingflanged fittings.5.6 Ring Joint Flange
A principle of design in this standard is to maintaina fixed position for the flange edge with referenceto the body of the fitting.The addition of any facingis beyond the outside edge of the flange except forthe 1.6 mm raised face in Class PN 20 and PN 50.
The edge (periphery) of each ring joint flange shallbe marked with the letter “R” and the corespondingring-groove number.
6.4 Reducing Fittings
Centre-to-contact surface or centre-to-flange edgedimensions for all openings shall be the same asthose of straight size fittings of the largest opening.The contact surface-to-contact surface or flangededge-to-flange edge dimensions for all combina-tions of reducers and eccentric reducers shall be aslisted for the larger opening.6.5 Side Outlet Fittings
6 FITTING6.1 Wall Thickness
For inspection purposes the minimum wall thick-ness Im of flanged fittings atthe time of manufactureshall be as shown in corresponding flanged fittingrating Tables 9 to 15 read with Fig. 3 for flangedfittings without base and Tables 16 to 21 read withFig. 4 for base type fittings. Additional metal thick-ness needed to withstand assembly stresses, shapesother than circular and stress concentrations mustbe determined by the manufacturer, since thesefactors vary widely. In particular, 45’ laterals, trueY’s and crosses may require additional reinforce-ment to compensate for inherent weaknesses inthese shapes.
6.2 Local DeformitiesLocal areas having less than minimum wall thick-ness will be acceptable provided that all of thefollowing are true:

b)4
The area of subminimum thickness may beenclosed by circle whose diameter is nogreater than 0.35 @“I where tm is the mini-mum wall thickness as given in respectivetable.Measured thickness is not less than 0.75 tm.Enclosure circles are separated from each
an edge distance of more than
Side outlet elbows, side outlet tees and side outletcrosses shall have all opening on intersecting centrelines, and the ceutre-to-contact surface dimensionsof the side outlet shall be the same as for the largestopening. Long radius elbows with side outlet shallhave the side outlet on the radial centre line of theelbow, and the centre-to-contact surface dimensionof the side outlet shall be the same as for the regular90’ elbow of the largest opening.6.6 Special Degree Elbows
Special degree elbows ranging from lo to 45’ inclu-sive shall have the same centre-to-contact surfacedimensions as 45’ elbows and those over 45’ andup to 90’ inclusive shall have the same centre-to-contact surface dimensions as 90’ elbows. Theangle designation of an elbow is its detlection fromstraight line flow and is also the angle between theflange faces.6.7 Auxiliary Connections
No auxiliary connections, or openings will be pro-vided except as specified by the purchaser. If as-sembly is required, the purchaser shall also specifythe applicable code or regulation. Welded auxiliaryconnections shall be made by a qualified welderusing a qualified weld procedure in accordancewith IS 2825 : 1969.

SIDE OUTLET TEE DOUBLE BRANCH SIDE OUT ELBOWELBOW
NOTE - The largest opening establishes the basicsize of a reducing fitting. The largest opening is named first, exceptthat for bull head tees which are reducing on both runs and for double branch elbows where both branches are reducing,the outlet is the largest opening and named last in both cases.In designating the openings of reducing fittings they should be read in the order indicated by the sequence of the lettersA, B, C and D. In designating the outlets of side outlet reducing fittings the side outlet is named last and in the case ofcross, which is not shown, the side outlet is designated by the IetterE.Sketches are illustrative only and do not imply required design.

NOTES
1 The hub dimensions shall be at least as large as those of the standard flanges of the size to which the reduction is being made,except flanges reducing to a size smaller than those of column 2 may be made from blind flanges. See Example 2.
2 PN SO flanges do not have a counterbore. DN 50 and higher pressure flanges will have depth of counterbore (g) of (6.4mm) forand smaller tappin and DN 50 (9.6 mm) for DN 65 and larger. The diameter(Q) of counterbore is the same as that given in thetables of threaded !langes for the corresponding tapping.
3 For method of designating reducing threaded flanges, see 4.2 and examples below.
Example 1
The size designation is DN 150 x 65 PN 50 reducing threaded flange.
This flange has the following dimensions:
318 mm diameter of regular DN 150 PN 50 threaded flange.
.37 mm thickness of regular DN 150 PN 50 threaded flange.
178 mm diameter of hub for regular DN 150 PN 50 threaded flange.
16 mm height of hub for regular DN 150 PN 50 threaded flange.
Other dimensions the same as for regular DN 150 PN 50 threaded flange, see Table 4.
Example 2
The size designation is DN 150 x 50 PN 50 reducing threaded flange.
Use regular DN 150 PN 50 blind flange tapped with DN 50 parallel threads.

8 For centre-to-contact surface and centre-to-end dimensions of special degree elbows, see 6.6.
9 For reinforcement of certain fittings, see 6.
10 For drains, see 6.7
11 Dimensions HH, JJ, KK, LL and MM apply to straight sizes only. See 6.4 and 6.8.4. For centre-to-end dimensions of reducingfittings or end-to-end dimensions of reducers, use centre-to-contact surface or contact surface to contact surface dimensions of2 mm raised face (flanged edge) for largest opening and add the proper height to provide for ring-joint groove applying to eachflange. Sea Table 23 for ring-joint facing dimensions.
12 When these fittings are required with flat-faced flange, either the full thickness or thickness with raised face removed may befurnished. Users are reminded that removing the raised face will make the centre-to-face dimension non-standard.
6.7.1 Pipe Thread Tapping
Holes may be tapped in the wall of a fitting if themetal is thick enough to allow the effective threadlength specified in Fig. 5. Where thread length isinsufficient or the tapped hole needs reinforcement,a boss shall be added.
6.7.2 Sockets
Sockets ( socket welding ) may be provided in thewall of a fitting if the metal is thick enough to affordthe depth of socket and retaining well specified inFig. 6. Where the wall thickness is insufficient, orthe size of the connection requires opening rein-forcement, a boss shall be added.
6.7.3 Butt- Weld
Connections may be attached by butt-weldingdirectly to the wall of the fitting as shown in Fig. 7.Where the size of an opening requires reinforce-ment, a boss shall be added.
6.7.4 Bosses
Where bosses are required, the diameters shall benot less than those shown in table under Fig. 8.

6.8 Facings ( Except Lap Joints )
6.8.1 Table 22 gives dimensions for facings otherthan ring-joint. Table 23 gives dimensions for ring-joint facings. Fig. 10 shows application of facings.PN 20 and PN 50 fittings and companion flangesare regularly furnished with a 1.6 mm raised facewhich is included jn the minimum flange thickness‘C’. Higher class fittings and companion flangesare regularly furnished with 6.4 mm raised facewhich is additional to the minimum flange thick-ness ‘C’.
6.8.1.1 For small male and female joints careshould be taken in the use of dimensions in Table22 to ensure that the inside diameter of fitting orpipe is small enough to permit sufficient bearingsurface to prevent the crushing of the gasket. Thisapplies particularly on lines where the joint is madeon the end of the pipe. Inside diameter of fittingshould match inside diameter of pipe as specifiedby the purchaser. Threaded companion flanges forsmall male and female joints are furnished withplain face. Large male and female faces and largetongue and groove are not applicable to PN 20because potential dimensional differ.
6.8.2 Go metal shall be cut from the minimumflange thickness specified herein except on class150 and 300 flanges; then the raised face may beremoved when bolting to cast iron flanges.
6.8.3 In the case of the 6.4 mm raised face, tongueor male face ( other than 1.6 mm ) raised face forPN 20 and PN 50, the minimum flange thickness‘C’ shall be first provided and then the raised face,tongue or male face shall be added thereto.
6.8.4 With ring-joint, groove, or female face, theminimum flange thickness shall be first providedand then sufficient metal added thereto so that thebottom of the ring-joint groove, or the contact faceof the groove or female face is in the same plane asthe flange edge of a full thickness flange.

10 C Flange Facings - Lapped Joints
NOTES1 See Table 22 for dimensions of facings (other than ring-joint) and Tabte 23 for ring-joint facing.2 For small male and female joints care should be taken in the use of these dimensions to ensure that the inside diameterof fittings or pipe is small enough to permit sufficient bearing surface to prevent the curshing of the gasket (see Table22). This applies particularly on lines where the joint is made on the end of the pipe. Threaded companion flanges forsmall male and female joints are furnished with plain face and are threaded with IS 3333 (Part 1 ) : 1967 threads.3 See Table 23.4 See Table 22.5 See corresponding fittings tables.6 Large male and female faces and large tongue and groove are not applicable to Class PN 20 because of potentialdimensional conflicts.7 See 6.9.8 See 6.9.5 and Table 23.

7.6.4 Other welding end preparations furnished byagreement of purchaser and manufacturer do notinvalidate compliance with this standard.
7.7 Reducing Flanges
7.7.1 Drilling Outside Diameter,,Thickness andFacing Dimensions
Flange drilling, outside diameter, thickness, andfacing are the same as those of the standard flangeof the size fTom which the reduction is being made.
7.7.2 Threaded and Slip-on Flanges
The hub dimensions shall be at least as large asthose of the standard flange of the size to which thereduction is being made. The hub may be larger oromitted as detailed in Table 8.
7.7.3 Welding Neck Flanges
The hub dimensions shall be the same as those ofthe standard flange of the size to which the reduc-tion is being made.
7.8 Threads for Threaded Flanges
Except as provided in Note 2, Fig. 10 threadedflanges shall have standard taper thread conformingto IS 3333 (Part 1) : 1967. The thread shall beconcentric with the axis of the flange and variationsin alignment shall not exceed 0.5 percent.
7.8.1 PN 20 flanges are made without a counter-b o r e . T h e t h r e a d s s h a l l b e c h a m f e r e dapproximetely to the major diameter of the threadat the back of the flange at an angle of approxi-mately 45’with the axis of the thread. The chamfershall be concentric with the thread and shall beincluded in the measurement of the thread length.
7.8.2 PN 50 and higher pressure flanges are madewith a counterbore at the back of the flange. Thethreads shall be chamfered to the diameter of thecounterbore at an angle of approximately 45’ withthe axis of the threads. The counterbore and cham-fer shall be concentric with the thread.
7.8.3 The minimum length of effective thread inreducing flanges shall be at least equal to dimensionT of the corresponding class of threaded flange asshown in the tables. Threads do not necessarilyextend to the face of the flange. See Table 8 forreducing threaded flanges.
7.8.4 The gaging notch of the working gage shallcome flush with the bottom of the chamfer in allthreaded flanges, and shall be considered as beingthe intersection of the chamfer cone and the pitchcone of the thread. This depth of chamfer is ap-proximately equal to one-half the pitch of thethread. The maximum allowable thread variation isone turn large or small from the gaging notch.
8 EOLTING
Stud-bolts threaded at both ends or full length, orbolts with heavy hexagonal heads may be used andshall have heavy nuts (see IS 1338 : 1966).
IS 13159 (Part 1) : 1993
8.1 Stud-bolts with a nut at each end are recom-mended for high temperature service. Stud-boltlengths specified in respective tables include thethickness of two nuts. The stud-bolt length does notinclude the height of any point. A point is that partof stud-bolt or a bolt beyond the thread may bechamfered, rounded, or sheared.
8.2 The method of calculating bolt lengths, shall begiven in Part 2 of this standard . These lengths areestablished for the convenience of industry to sim-plify the assembly of these parts on constructionwork, but users may select combinations of thesebolt lengths to suit their needs.

NOTES’1 See 7.6, 7.7 and 9.5 for details and tolerances.2 See Fig. 13 and 14 for additional details of welding ends.3 When the thickness of the hub at the bevel is greater than that of pipe to which the flange is joined and the additionalthickness is provided on the outside diameter, a taper weld having a slope not exceeding 1 to 3 may be employed or,alternatively, thegreateroutsidediameter may betapered,at thesamemaximumslopeor less,from a point on theweldinglevel equal to the outside diameter of the mating pipe. Similarly, when the greater thickness is provided on the inside ofthe flange, it shall be taper-bored from the welding end at a slope not exceeding 1 to 3.4 When flanges covered by this standard are intended for services with light wall, higher strength pipe, the thicknessof the hub at the bevel may be greater than that of the pipe to which the flange is joined. Under these conditions a singletaper hub may be provided and the outside diameter of the hub at the base ( Dimension X) may also be modified.5 The additional thickness may be provided on either inside or outside or partially on each side, but the total additionalthickness shall not exceed one-half times the nominal wall thickness of intended mating pipe (see Fig. 15,16 and 17).

1 STD = Standard Wall Thickness.XS = Extra Strong Wall Thickness.XXS = Double. Extra Strong Wall Thickness.
2 For tolerances ( see 9.5 ).3 It should be recognized that there is no fixed relation between pressure classes and pipe schedules.4 When the wall thickness is less than 14.33 mm, it may be necessary to provide additional material by weld-depo-
sition in order to be able to machine to the ‘C’ dimensions.5 This table covers a few popular sizes only. User may calculate dimensions for other sizes based on formula given
