Flanges

Flanges - General Information A Flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed into such systems and then joined with bolts.

Flange Types :HOG1HFN This flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications

6OLSRQ This flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.

%OLQG This flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover. It is sometimes referred to as a blanking flange.

6RFNHW:HOG This flange is counter bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same therefore giving good flow characteristics.

7KUHDGHG This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required.

/DS-RLQW These flanges are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. The lap joint is favoured in low pressure applications because it is easily assembled and aligned. To reduce cost these flanges can be supplied without a hub and/or in treated, coated carbon steel.

5LQJ7\SH-RLQW This is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flanges.

Notes 1 MSS SP-44 flanges are designated Series A flanges in ASME B16.47. 2 API 605 has been cancelled. API 605 flanges are designated Series B flanges in ASME B16.47. 3 BS 10, although obsolete, remains in use for light weight economy stainless steel flanges. 4 Within specification ANSI B16.5, plate can only be used to provide blind flanges. 5 Most small BS 10 flanges are made from bar. 6 Castings are not included in this manual.

Materials. Most standards specify the material from which the flange is produced. The purchaser should specify the exact requirements. Flange Sizes. All sizes and grades compatible to standard pipe ranges and wall thicknesses (pressure ratings) are available. The table below provides a summary. Flange Face. There are various face configurations for flanges. Typically: flat face, raised face, tongue and groove, ring joint.

Face Finish. The finish on the face of a flange is measured as an Arithmetical Average Roughness Height (AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH 500AARH (3.2 Ra to 12.5 Ra). Other finishes are available on request, for example 1.6 Ra max, 1.6/3.2 Ra, 3.2/6.3 Ra or 6.3/12.5 Ra. The range 3.2/6.3 Ra is most common.

Notes 1 MSS SP-44 flanges are designated Series A flanges in ASME B16.47. It also covers flanges in the range NPS 12 to 24, these being equivalent to ASME/ANSI B16.5 flanges in the same range (except for the addition of NPS 22 in MSS SP-44). 2 API 605 has been cancelled. API 605 flanges are designated Series B flanges in ASME B16.47. Ranges quoted are based on ASME B16.47 Series B. 3 Dimensions not covered in this summary.

Flanges

ASME/ANSI B16.5-1996 and B16.47-1996 American national standards ASME/ANSI B16.5 and B16.47 together cover pipe flanges up to NPS 60 (NPS 48 is the largest detailed in this summary). ASME/ANSI B16.47 covers two series of flanges, Series A which is equivalent to MSS SP-44 (the 1996 Edition of MSS SP-44 complies with B16.47 tolerances), and Series B which is equivalent to API 605 (API 605 is now cancelled).

Notes Ring joint gasket dimensions conform to ASME B16.20 (not covered in this summary). Use Class 600 lb in sizes NPS 1/2 to NPS 31/2 for Class 400 lb. Use Class 1500 lb in sizes NPS 1/2 to NPS 21/2 for Class 900 lb. Tolerances are as shown in the table below. 1 The height of the raised portion is equal to the depth of groove dimension L, but is not subject to the tolerances for L. 2 Ring joints with lapped flanges in Classes 300 lb and 600 lb use R30 instead of R31.

Class 300 and higher threaded flanges are counter-bored. Threads are chamfered to the counterbore at an angle of 45° (approx). Weights are based on manufacturer’s data and are approximate. For tolerances see page 8-4.

Notes ASME B16.47 Series A flanges (> NPS 26) are MMS SP-44 flanges. MSS SP-44 also covers NPS 12 to NPS 24 flanges which are equivalent to ASME B16.5. MSS SP-44 is the only source for the NPS 22 flange dimensions above. Dimension B is to be specified by the purchaser. It corresponds to the pipe inside diameter. Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is nonstandard). WNF = Weld Neck Flange. The large end of the hub may be straight or tapered.

Notes ASME B16.47 Series A flanges (> NPS 26) are MMS SP-44 flanges. MSS SP-44 also covers NPS 12 to NPS 24 flanges which are equivalent to ASME B16.5. MSS SP-44 is the only source for the NPS 22 flange dimensions above. Class 400 Series A dimensions at NPS 38 and larger also apply to Class 400 Series B flanges. Dimension B is to be specified by the purchaser. It corresponds to the pipe inside diameter. Flat face flanges may be provided at full thickness, C + raised face, or with raised face removed (the latter is nonstandard). WNF = Weld Neck Flange. The large end of the hub may be straight or tapered. For ring joint facings see page 8-6. For weld end bevel see page 8-5. For tolerances see page 8-4.

Notes ASME B16.47 Series B flanges are API 605 flanges. API 605 has been cancelled. Dimension B is to be specified by the purchaser. It corresponds to the pipe inside diameter. Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is nonstandard). WNF = Weld Neck Flange. The large end of the hub may be straight or tapered.

Flanges

BS 4504 Circular Flanges - General British Standard BS 4504 : Section 3.1 : 1989 - Circular Flanges for Pipes, Valves and Fittings (PN Designated), Specification for Steel Flanges. This covers flanges in nominal pressure ranges PN 2.5 to PN 40 and nominal sizes up to DN 4000 (see table below). BS 4504 substantially agrees with ISO 7005-1 : 1992 (E) Part 1 : Steel Flanges. BS 4504 : 1969 is still commonly used. This older standard allows for manufacture from bar, whereas the latest standard specifies that forging or plate are to be used, which can be significantly more expensive. There are minor differences in dimensions between the two versions. The following tables are based on the later version. Summary of flanges covered by BS 4504 : Section 3.1 Code No. 101 102 104

Description Plate flange for welding (see page 8-65) Loose plate flange with weld-on plate collar or for lapped pipe end (Weld-on plate collar = Code 1321 Lapped pipe end = Code 1331) Loose plate flange with weld-neck collar (Weldneck collar = Code 1341)

Notes 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 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

Manufacture ❍

Materials. Flange codes 111 112 and 113 are manufactured from a forging or steel casting. Stainless steel forgings conforming to ASTM A 182, have an additional requirement for grade F304L and F316L that carbon content (by ladle analysis) shall be 0.030% max. Forgings to BS 1503 and comparable ASTM standard grades specified in BS 4504 are as listed in the following table.
