    AWWA standards describe minimum requirements and do not contain all

    of

    the engineering and

    administrative nformation normally contained in specifications. The AWWA standards usually

    contain options that must be evaluated by the user of the standard. Until each optional feature is

    specified by the user, the product

    or

    service is not fully defined. AWWA publication

    Introduction.

    I.A.

    Background.

    American National Standards Committee A21 on Cast-Iron

    Pipe and Fittings

    was

    organized in 1926 under the sponsorship of the American Gas

    Association (A.G.A.), the American Society for Testing and Materials

    (ASTM),

    he

    American Water Works Association (AWWA), and the New England Water Works

    Association (NEWWA).Between 1972 and 1984, the cosecretariats were A.G.A.,

    AWWA, and NEWWA, with AWWA serving as administrative secretariat. In 1984,

    the committeebecame an AWWA committee with thename AWWA Standards

    Committee A21 on Ductile Iron Pipe and Fittings. In 1988, NEWWA withdrew as

    a

    separate secretariat; however, it continues to mainta in its represen tation n the A21

    Committee. In 1997, A.G.A. withdrew as cosecretariat.

    The present scope of Committee A21 activity is the prepara tion

    f

    standards for

    cast-iron and ductile-iron pressure pipe for gas, water, and other liquids, and fittings

    for usewith uch pipe. These standards include design, dimensions, mater ials,

    coatings, linings, joints, accessories, and methods of inspection and testing.

    The work of CommitteeA21 is conducted by subcommittees. The scope of

    Subcommittee 3 , Fittings, includes the periodic review of all current A21 standards

    for fittings and the preparation of revisions and new standards, when needed, for

    fittings t o be used with cast-iron and ductile-iron pressure pipe included in A21

    standards.

    I.B. History. The evolution of AWWA and

    ANSI

    standards for fittings is

    presented in this foreword t o provide information relating t o systems having aged

    cast-iron pipe and fittings still inservice.

    The earliest record of an AWWA standard for cast-iron pipe is contained in the

    Report of Proceedings of the Tenth Ann ual Meeting of the American Water Works

    Association

    (1890). In 1902, NEWWA adopted

    a

    more detailed standard itled

    “Standard Specification for Cast Iron Pipe and Special Castings.”

    The next AWWA standard for pipe and fittings,AWWA 7C.1-1908,was approved

    May 12, 1908. A second edition, AWWA C100-52T, was approved by AWWA Dec.

    31,

    1952, and byNEWWA Ja n. 23, 1953. The third edition, AWWA C100-54T, was

    approved by AWWA Oct. 25, 1954, and finally issued

    as

    AWWA C100-55, having been

    advanced from tentative t o standard without change June 17, 1955. AWWA C100-55

    covered fittings in the size range

    4

    o 60 in. (102 to 1,500 mm).* The fittings were all

    bell and spigot (caulked oint)

    of

    the so-called long-radius design. Theoutside

    diameter

    (OD)

    for spigots varied with wall thicknesses, which were designated classes

    A, B, C, and

    D.

    Fittings 4 to 12 in. (102 to 305 mm) were made to class D patterns,

    having only one OD and pressure rating. Fittings14 to 24 in. (356 t o 610 mm) in size

    were furnished in classes

    B

    and D, and fittings 30 to 60 in. (762 to

    1,500

    mm) in size

    were furnished in classes A, B, C, and D. All fittings made in ccordance with AWWA

    7C.1-1908 and C100-55 had the class identification cast on the fitting.

    “Metric conversions given in this standard are direct conversions

    of US

    customary units

    and are not those specified in the Interna tional Organization

    for

    Standardization (IS01

    305-mm) fittings of the so-called short-body design, whichwere the subject of

    extensive research and tests by Committee A21. The rated pressure givenby the

    standard was 250 psi (1,724 kPa) plus waterhammer. The standard provided a safety

    factor of 2.5 pluswaterhammer based on burs t ests, Hydraulic losses were

    determined and compared with those found with long-radius fittings manufactured

    in accordance with AWWA Standards. Theminimum grade

    of

    cast ron n the

    standard was 25,000 psi (172.4 MPa) tensile strength.

    ASA A21.10-1964 (AWWA C110-64) was approved byASA Jan. 9, 1964. The

    revision covered 2-

    to

    48-in.

    (50- to

    1,219-mm) fittings. The design

    of

    the 14-

    to

    48-in.

    (356- to 1,219-mm) fittings in the revision was based on an exhaustive series of burst

    tests. The minimum grade of cast iron (25,000 psi [172.4 MPa] tensile strength) was

    retained, and higher grades up o 35,000 psi (241.3 MPa) tensile strength were used

    to secure higher pressure ratings without adically changing the thicknesses. Ductile

    iron, grade 80-60-03, was also added in the 14- t o 48-in. (356- t o 1,219-mm) sizes with

    a rated working pressure of 250 psi (1,724 kPa), having he same wall thicknesses as

    150-psi (1,034-kPahratedgray-ironfittings. Theminimum safety factor based on

    burs t tests of representative fittings

    of

    the weakest type was three times the rated

    working pressure. Tables for flanged fittings and mechanical-joint fittings were

    added for the first time.

    ANSIA21.10-1971 (AWWA 2110-71) was approved byANSI July 14, 1971.

    Ductile-iron fittings were added in sizes 3 to 12 in. (76 to 305 mm) and were rated

    for

    350 psi (2,413 kPa) working pressure, The grade

    of

    ductile iron waschanged t o

    70-50-05

    to

    provide greater toughness. The safety factor against bursting was three

    times the rated working pressure. If required by the purchaser on special order,

    fittings were required to withstand a hydrostatic proof test not to exceed one and one

    half times the rated working pressure without leaks r permanent distortions.

    ANSIA21.10a-1972 (AWWA C110a-72) was approved Dec. 17, 1972, as a

    supplement to ANSI A21.10-1971. The pressure rating

    for

    14-

    to

    24-in. (356-

    o

    610-mm)

    ductile-iron fittings was increased to 350 psi (2,413 kPa).

    ANSUAWWA C110-77

    (ANSI

    A21.10) was approved by ANSI Apr. 7, 1977. The

    major change in this revision was the discontinuance

    of

    bell-and-spigot fittings (caulked

    joints) and 2- and 21/4-in. (50- and 56-mm) fittings in the standard. These actions

    were taken because the use

    of

    caulked joints had steadilydeclined until their use had

    become a rarityand he 2- and 21/4-in. (50- and 56-mm) sizes were no longer

    manufactured in the United States. (Bell-and-spigot fittings are still available from some

    foundries on special order.) With the elimination of 2- and 21/4-in.

    (50-

    and 56-mm)

    sizes, the standard ncluded

    3- to

    48-in. (76- o 1,219-mm)mechanical-joint and flanged

    fitt ings only.

    Another change made in the 1977 edition was in bolt lengths for flanged fittings

    to comply with ANSIIAWWA C115lA21.15-75, Standard

    for

    Flanged Cast-Iron and

    Ductile-Iron Pipe With Threaded Flanges. Appendix A was added to the standard to

    cover bolts, gaskets, and the installationof flanged fittings. Appendix B was added as

    a listing of available special fittings that arenot a part

    of

    the standard.These include

    III. Use

    of This Standard.

    AWWA has no responsibility for the suitability or compatibility of the provisions

    of this standard to any intended application by any user. Accordingly, each user

    of

    thisstandard s responsible for determining tha t he standard's provisions are

    suitable for and compatible with that user's intended application.

    1II.A. PurchaserOptions ndAlternatives. This standard includes ertain

    options tha t, if desired, must be specified in the purchaser's specifications.

    It

    is also

    necessary that such options be included on the purchase order. Also, a number of

    items must be specified

    to

    describe completely the fittings required. The following list

    summarizes the detailsandavailable options, andreferences the sections of the

    standard where they are found.

    1. Size, joint type, pressure rating (Sec. 1.1 and tables).

    2. Joint requirements (Sec. 4.2.1 and 4.2.2).

    3. Type

    of

    iron (Sec. 4.2.4).

    4. End combinations (Sec. 4.2.5).

    5 . Certification by manufacturer (Sec. 5.1.3).

    6 .

    Inspection by purchaser (Sec.

    5.2).

    7 . Elimination of cement-mortar lining (Sec. 4.3.2).Experience has indicated

    that the petroleum asphaltic inside coating isnot complete protection against loss in

    pipe capacity caused by tuberculation. Cement-mortar linings are recommended for

    most waters.

    8.

    Special coatings and linings (Sec. 4.3.3).

    9. Acceptance tests (Sec. 5.4).

    10. Special tests (Sec. 5.6).

    11. Special flange bolt-hole orientation (Sec. 4.4.3).

    1II.B. Special Service Requirements. The following special service requirements

    1. The fittings for which this standard is ntended are those normally used for

    water. Fittings for other services may require special consideration by the purchaser.

    2. The method of installat ion of fittings depends on the type of joint and

    should be made in accordance with applicable parts

    of ANSI/AWWA

    C111/A21.11,

    Rubber-Gasket Joints for Ductile-Iron and Gray-Iron Pressure Pipe and Fittings;

    ANSUAWWA C600, Installation of Ductile-Iron Water Mains and Their Appurte-

    nances; and recommendationsof manufacturers regarding their product.

    3. Attention s directed to an apparen t conflict between this standard and

    ASME/ANSI B16.1, Cast Iron Pipe Flanges and Flanged Fittings, with regard to

    pressure ratings for flanged fittings.

    In ANSUAWWA CllO/A21.10, flanged joint fittings are rated for 150 or 250 psi

    (1,034 or 1,724 kPa) working pressure, depending on the materia l, that is,gray iron

    or ductile iron; he wall thickness of gray iron; and he size

    of

    the fitting. The ratings

    of these fittings were established on the basis

    of

    hydrostatic testing

    of

    fittings

    to

    bursting and providefor afactor of safety of at east 3.0 at he rated working

    pressure and at ambient temperature. ANSI/AWWA CllO/A21.10 flanges that ar e

    adequate for water service of

    250

    psi (1,724 kPa) working pressure have facing and

    drilling identical to ASME/ANSI B16.1 class 125 flanges, and match class 125 B16.1

    flanges, that for service at -20 to 150°F (-28.9' to 65.6 C)are rated for only 150 t o

    200 psi (1,034 to 1,724 kPa), depending on the flange size and the class

    or

    grade of iron.

    should be noted:

    ASME/ANSI B16.1 covers both separate flanges and flanged fittings of gray iron

    for service at both ambient and elevated temperatures. The pressure-temperature

    ratings of these flanges, as set forth in ASME/ANSI B16.1 and stated on the flyleaf

    of that standard, are ot based on burst strength, buthave evolved over an extended

    period of time of satisfactory performance ina wide range of general service

    conditions. These ratings encompass pressure combined with elevated temperature,

    stresses imposed by piping, thermalstressesdue to temperaturevariations,and

    many other conditions causing stress in the flange or fitting.

    ASME/ANSI B16.1 also contains the design of a class 250 flange, which is much

    heavier, has a larger bolt circle, and uses larger-sized bolts than the B16.1 class 125

    flange and he flanges covered inANSUAWA C115/A21.15 and hisstandard.

    ASME/ANSI B16.1 class 250 flanges will not connect to the B16.1 class 125 flange,

    the ANSUAWWA C115/A21.15 flange, or the ANSUAWWA CllO/A21.10 flange.

    4. Although this standard does not detail the orientation of bolt holes in the

    flanges

    of

    the mechanical joint, i t is at times convenient or necessary t o have the bolt

    holes specially oriented. The normal but not universal practice is

    to

    have the bolt holes

    straddle the vertical centerline of the fittings, valves, and hydrants. (The vertical

    centerline of a fitting is determinedwhen the fitting is n the position to change the

    direction

    of

    fluid flowing inahorizontalplane. With standard base bends and

    standard base ees, the vertical centerline is determined when the fitt ing is in a

    position t o change the fluid flowing in

    a

    vertical plane.) If special orientation is

    known t o be necessary, it should be stated on the purchase order.

    1II.C.

    Mod if icat ion to Standard.

    Any modification to the provisions, definitions,

    or terminology in this standard must be provided in the purchaser’s specifications.

    IV. Major Revisions. Themajor revisions made to thisstandard in this

    edition are as follows:

    1. The format has been changed to AWWA standard style.

    2. Section I.A,Background,was revised torecognize the withdrawal of the

    American Gas Association as cosecretariat of the A21 Committee.

    3 . The acceptance clause (Sec. 1 . 0 has been revised to approved wording.

    4. The advisory information paragraph

    (Sec.

    1I.A) was revised and moved

    from the body of the standard into the foreword.

    5.

    The cope of the tandardhas been limited to water service andall

    references t o gas and other liquids have been eliminated.

    6. The scope was amended to recognize 350-psi (2,413-kPa) ratings for 12-in.

    (305-mm) and smaller flanged ductile-iron fittings when used with special gaskets.

    7. Cement-mortar inings (Sec. 4.3.2) was revised t o reflect the optional

    status of seal coat in the late st evision of ANSUAWWA C104/A21.4.

    8.

    Special coatings and inings (Sec. 4.3.3) was revised to include asphaltic

    material as a special lining.

    9. Table 1 was revised in accordance with the 1995 revision of ANSVAWWA

    C111/A21.11. Revisions include plus olerances on the K I ,

    K z ,

    and L dimensions;

    longer bolt lengths for the

    42-

    and 48-in. (1,067- and 1,219-mm) sizes; and he

    footnote on ductile-iron glands.

    10. Tables 16 through 19 on flanged fittings were revised t o show the use of

    ductile iron for

    3-

    t o 12-in. (76- to 305-mm) flanged fittings with the samedimensions

    as gray-iron fittings. Explanatory footnotes were also added.

    11. The gaskets section of appendix A was revised t o describe the ubber

    material as being synthetic.

    REQUIREMENTS

    Sec. 4.1 Permeation

    The selection

    of

    materials is critical for water service and distribution piping n

    locations where the re is likelihood the pipe will be exposed

    to

    significant concentra-

    tions of pollutants composed of low molecular weight petroleum products or organic

    solvents o r their vapors. Research has documented that pipe materialssuchas

    polyethylene, polybutylene, polyvinyl chloride, and asbestos cement, and elastomers,

    such as used in jointing gaskets and acking glands, may be subject to permeation by

    lower molecular weight organic solvents or petroleum products. If a water pipe must

    pass through such a contaminated area

    or

    an area subject to contamination, consult

    with the manufacturer regarding permeation of pipe walls, jointing materials, and o

    forth,

    before

    selecting materials

    for

    use in that area.
