Sleeves may be furnished as castings or fabrications, at Foundry option.*This thickness and other dimensions, weights, etc will vary slightly because of manufacturing process. Collars welded

on fabricated sleeves will be steel.**The 54" Mechanical Joint Wall Sleeve is special with special mechanical joint (gland weight: 360 lbs each; gasket

weight: 7 lbs each; 36-11⁄4" X 6" stud bolts each with one hex nut and weighing 3.4 lbs each). Consult AMERICAN foradditional information on this special sleeve and for information on 60" & 64" wall sleeves.

Some sizes of wall sleeves in shorter lengths than shown can be furnished by special pattern adaption. Check AMERI-CAN if required.

†This “Weight per 1" Increment of Length” is the weight to add to — or subtract from — the weight of the 12"-longwall sleeve for each 1" variation in sleeve length from 12".

Sleeves will be furnished tapped for studs. Wall collar will be furnished approximately in center unless otherwise speci-fied. Minimum distance from the sleeve end to the center of the collar is 4" for 4"-24" sizes, 5" for 30"-60". For sizes 4"-24", wall collar can be positioned on sleeve in 1" increments; for sizes 30"-54" in 2" increments.

Overall lengths are subject to manufacturing tolerances. If maximum overall length is critical, such as for installation ofitem inside steel forms, this must be specified on order.

See General Notes on page 7-1.

7-3

*AWWA C151 - minimum thickness classes in this standard are Class 350 for 4"-12" sizes, Class 250 for 14"-20"sizes, Class 200 for 24" and Class 150 for 30"-64" sizes.

**AWWA C115 - minimum thicknesses for all sizes of ductile iron pipe for threading on flanges.Wall pipe is normally fabricated of Special Class 53 thickness ductile iron pipe but may be furnished with minimum

classes unless threaded flanges or threaded MJ bells are included or unless specified otherwise. For weights of Plain EndPipe of other classes see Section 3, Table No. 3-9.

†These values are based on dead-end thrust due to 250 psi internal pressure. For higher allowable loads or pressures,check AMERICAN. (See also the figure above Table No. 9-11, for use of thrust collars, e.g., in some buried systemswhere other types of concrete thrust blocks cannot be used.)

Welded-on thrust collars are normally fabricated from steel. Dimensions and weights above are for steel thrust collars.If collars are to be furnished of annealed ductile iron, dimensions and weights are the same as in Table No. 7-3 forwall collars.

Collars may be angled and/or rotated from top dead center (TDC). Check AMERICAN for details.See General Notes on page 7-1.

*Laying lengths are rounded to the nearest 1/4".Thrust Collars may not be located in exact center of all minimum length

pieces shown above.Flanges and MJ bells of minimum-length pieces should normally be

specified by the purchaser “tapped for studs” to enable assembly of jointsflush with the wall face.

Maximum laying length of above wall pipe is 19'-6" (except 17'-6" for 4" and19'-0" for 64") except for MJ-T/C-PE or Fst-T/C-PE which may be furnished full20' nominal length in all available sizes with the exception of 4" (4" maximumlength is 18'-13/4"). 6"-16" Flange-Thrust Collar-Flange and Flange-Thrust Collar– PE pipe may also be furnished up to 20'-0" length (with the exception of 4"whose maximum length is 17'-6"). Check AMERICAN if longer lengths required.All intermediate lengths can be furnished.

Wall pipe lengths shorter than those shown above can be furnished in

some sizes by special fabrication. Check AMERICAN for details.Overall lengths are subject to manufacturing tolerances. If maximum

overall length is critical, such as for installation of item inside steel forms, thismust be specified by the purchaser on the order.

To determine weight of Thrust Collars Wall Pipe, use data in Table 7-2.Correctly installed flanged wall pipe will normally have the bolt holes

straddling the horizontal and vertical centerlines. Checking with a spiritlevel or plumb line prior to pouring the walls is recommended.

Wall pipe with MJ threaded-on bells (MJ Fab), Flex-Ring, and Lok-Ring bellscan also be furnished. Check AMERICAN for dimensions not shown above.

Minimum-length pipes with plain ends (PE) in many cases do not allowenough room between PE and collar to assemble joints. Contact AMERICANfor PE joint assembly needs, normally requiring longer pipes.

*The minimum dimension “B” for 42"-64" wall castings with threaded-on (AWWA C115) flange would be as follows: for42", B = 6"; for 48", B = 61⁄2"; for 54"-64", B = 71⁄4".

Dimensions are based on standard mechanical joints per AWWA C111 and standard flanges per AWWA C110.Wall piping with MJ bells or flanges having “A” and “B” dimensions shorter than those above, e.g. wall pipes with bell

faces often placed “flush” with concrete form work, should be specified to be tapped for studs.“A” and “C” dimensions for 14"-48" sizes apply to MJ castings only.

AMERICAN Ductile Iron SpecialsWelded-on Outlets for Ductile Iron Pipe

AMERICAN regularly furnishes pipe withwelded-on outlets for proven effectiveness andsimplicity in layout and installation. Outlets canreadily be located at variable positions along thepipeline, and rotation* of the pipe before it isassembled in the line can often position theoutlet at any desired angle. This section providesdetailed tabular data for 90º lateral andtangential welded-on outlets. Lateral outletsfrom 45º-90º in 15º increments from the parentpipe axis are also standardly available in somesizes with some additional outlet size restrictions.(Contact AMERICAN for details.)

JOINTS. The outlets are fabricated fromcentrifugally cast ductile iron pipe, manufacturedand tested in accordance with ANSI/AWWAC151/A21.51. They may be furnished with any ofAMERICAN’s bell ends such as Fastite, MJ, Flex-Ring, or Lok-Ring. They can also be furnished withplain ends. The parent pipe can also be furnishedwith any type of joints.

THICKNESSES. Minimum nominalthicknesses for both parent and outlet pipe areshown in the following tables. The outlets are rated200 to 250 PSI working pressure, depending onsize, as noted in Table No. 7-16. Check AMERICANfor higher pressure applications.

* Do not attempt to lift or rotate outlet pipes by attaching toor exerting force on the outlet or any branch piping attachedthereto. Likewise, do not attach and suspend heavy pipingitems, etc., from outlet branch.

** Larger-diameter outlets may be available for some pressure and ser-vice applications. Check AMERICAN for details.

† “J” dimensions are approximate and are the same for all different out-let sizes on a particular parent pipe size. Check AMERICAN if differentdimensions are required.

†† Minimum ”B” dimensions are dependent on outlet diameter and arenot directly related to parent pipe diameter. For example, a “B” dimensionfor 6" outlets on all sizes of parent pipe (including 10") is 15 1/2", etc.

Nominal thickness of 4"-54" diameter parent pipe and outlet pipe corre-spond to Special Class 53. Nominal thicknesses of 60" and 64" parent pipecorrespond to Pressure Class 350 as shown in ANSI/AWWA C151/A21.51.

System design and installation should be such so as to avoidbeam loads or impacts on the outlets. It is particularly important in underground service to use flexible joints (e.g., Flex-Ring or Fast-Grip) for outlet piping, to allow for at least some incidental movementbetween the parent and outlet piping. It should be noted that AWWAManual M41 and the Appendix to ANSI/AWWA C115/A21.15 statethat underground use of the flanged joint is generally not recom-mended because of the rigidity of the joint, and AMERICAN concurswith this guidance. Flexible outlet pipe joints should not be modifiedto make them rigid, nor should they be installed fully deflected.

By its nature, ductile iron pipe possess-es tremendous columnar and tensilestrength, which makes it a superior materialfor trenchless applications. AMERICANoffers four joints designed for use in directjacking, trenchless pipeline replacement,pipe bursting, and microtunneling installa-tion. MTTM Push Pipe is used primarily forpressure applications, and GS® Push Pipe isused for gravity sewer applications. FastiteJoint Push-Bar Pipe allows the Fastite Jointto be used in trenchless applications usingdirect jacking or pushing. Flex-Ring® jointpipe with its positive, flexible joint restrainthas been used extensively in pipe-pullingapplications utilizing horizontal directionaldrilling and some pipe bursting installationmethods. A “Suggested General Guidelinesfor Horizontal Directional Drilling (HDD)Installations of Ductile Iron Pipes” docu-ment is available from AMERICAN, o r o n l i n e i n p d f f o r m a t f r o mwww.acipco.com/adip. With spigots ahead,the low profile Flex-Ring® assembles quicklyand offers a smooth transition during pipepull-back. AMERICAN offers a Flex-Ring®

pu l l i ng be l lassembly specifi-cally designed forthis installationmethod.

MTTM PushPipe is a bell-lessductile iron pipecapable of func-

tioning in either gravity or pressure applica-tions up to 350 psi in 4"-12" sizes or 250psi in 14"-16" sizes. The joint is formed bycounterboring both ends of an extra thick(Special Thickness Class 55) ductile ironpipe. An independent, internal, stainlesssteel coupling with double 1/4" O-Ringgrooves is utilized in this joint configuration.The MTTM Push Pipe was developed primar-ily as a pipe to be used in the microtunnel-ing process that requires the pipe to resistsignificantly large pushing loads.

GS® Push Pipe is also a bell-less ductileiron pipe also used in microtunneling andother pushing applications capable of providing a positive seal for gravity or low

head applications up to 100 feet (43 psi) in4"-16" sizes. It consists of an extra thick(Special Thickness Class 56) pipemachined to form an internal bell anddouble O-Ring gasketed spigot. Becausethe joint is precision machined, it efficientlytransfers the jacking loads through thejoint, therefore maximizing the potentiallength of installation.

Candidate ductile iron pipe for bothMTTM Push Pipe and GS® Push Pipe fabrica-tion is manufactured and tested in accor-dance with ANSI/AWWA C151/A21.51.Counterbored joint surfaces are coveredwith an epoxy coating. The pipe comes in a20' or less standard nominal laying lengthsas shown in the following tables – shorterlengths are available if required.

Push-Bar Pipe employs an economicaladaptation of the premier AMERICAN FastiteJoint to transfer jacking loads from the pipebarrel directly to the face of the bell. It con-sists of a high-strength, alloy steel ring, the“push-bar,” shop welded to the standardFastite pipe spigot. This ring is made of thesame material that has been used successful-ly in AMERICAN’s Lok-Ring and otherrestrained joints for over 30 years. A cushion-ing compression ring, made of compressiblewood products, fits between the push-barand the pipe bell for added assurance of loaddistribution. The pipe comes in standard 20'or less standard nominal laying lengths andcarries the standard Fastite Joint pressure rat-ings. During installation, Fastite Joint Push-Bar Pipe is jacked or pushed with the spigotsahead. This allows for any debris remainingfrom the pipe bursting or pipe jacking opera-tion to flow smoothly over the bell of theFastite Joint.

Flex-Ring joint pipe and allowablepulling loads are covered in Tables 7-18 and7-2. See above picture of Flex-Ring pullingbell assembly at left.

Cement-mortar lining per ANSI/AWWA C104/A21.4 and asphalt exteriorcoating per ANSI/AWWA C151/A21.51are standard for Flex-Ring, MTTM Push Pipe,GS® Push Pipe, and Push-Bar Pipe. Otherlinings and coatings are available for specificservice conditions.

Shown below are sketches of three cases of long-span or pipe-on-supports situa-tions. Case #1 shows traditional pipe-on-supports installations where one support isprovided for each length of pipe. Cases #2 and #3 show long-span pipe assemblies thatutilize AMERICAN’s Toruseal® gaskets. Other pipe assemblies using other AMERICANjoints may be possible depending upon circumstances. Notes under each case apply tothat case. General notes are shown at the end.

LONG SPAN AND PIPING SUPPORTS

*Check AMERICAN on long-span requirements involving 4” pipe.**See Sections 6 and 8 for details on Toruseal Gaskets.

Approx. 20' Max.

(Typ.)

Approx. 2' (Typ.)

Case #1

Case #1 utilizes 20' or less lengths of Fastite, MJ, or other push-on restrained pipe.(See page 7-29 General Note 3.) This length is normally subject to normal manufactur-ing and trim (cut pipe) variations, with some pipe allowed up to two feet shorter thanfull length. Where exact length pipe is required, say to fit existing pier spacings, etc.,check AMERICAN.

Minimum pressure classes of all sizes of ductile iron pipe are more than adequateto support the weight of the pipe and the water it contains in Case #1 installationswhen analyzed and installed in accordance with the suggestions in the Ductile Iron PipeResearch Association’s procedure for “Design for Ductile Iron Pipe on Supports.” Thisprocedure is available from AMERICAN.

The beam strength of ductile iron pipe, along with the capability of certain AMERI-CAN joints, allows the installation of clear spans of up to 48' or more in sizes 6”* - 64”.This was made possible due to the advent of AMERICAN’s unique Toruseal® gaskets**in the 1970s.

7-28



APPROX. 48' - 0" STD.

APPROX. 2' - 0" STD.9' - 6"19' - 3" (TYP.) 19' - 3" (TYP.)

Case #3

Case #3 utilizes 19’-3” lengths of flange-bell and flange-plain end pipe with a 9’-6” flange-flange pipe in the center. This can result in more mid-span deflection thanCase #2 and, therefore, it is normally used only in 18” and larger sizes.

The 48’ clear span distance for Case #3 has been increased in larger pipe size appli-cations by lengthening the 9’-6”-long center pipe (maximum possible with three full-length pipes is 58’-6”). Check AMERICAN on requirements greater than 48’ or forlonger desired spans in smaller pipe sizes than is illustrated in Case #2.

Since Case #3 utilizes flanged pipe joints, minimum nominal thicknesses for fabri-cated flanged pipe shown in AWWA C115 are required.

Approx. 38'-6" Std.

Approx. 2' (Typ.)

Case #2

Case #2 utilizes 19’-3” lengths of flange-plain end and flange-bell (Fastite, MJ, orother push-on restrained) pipe. (MJ pipe is not available over 12” in diameter.) SinceCase #2 utilizes flanged pipe joints, minimum nominal thicknesses shown in AWWAC115 are required.

GENERAL NOTES1. Principles presented in the DIPRA publication “Design of Ductile Iron Pipe

on Supports” can be used to calculate the maximum localized stress due to supportreaction and to approximate the maximum beam-bending stress near mid-span ofthese systems. This publication can be obtained from AMERICAN.

2. Small-diameter pipe systems with very long unsupported pipe spans canexhibit visible mid-span deflection, or “sag.” While this deflection results in nostructural problems, the designer may consider means to reduce or eliminate mid-span deflection if aesthetic or other concerns are anticipated in the application.

3. Push-on or push-on restrained joint pipe is normally a better choice thanmechanical joint pipe due to more tolerance for thermal expansion and contraction,movement effects, and other aspects. Mechanical joints are not available fromAMERICAN for ductile iron pipe over 12”.

4. Where pipeline bends adjacent to crossings are externally restrained forrestraint of axial pressure thrust, or where there are no bends adjacent to crossingsto result in such thrusts, it is quite common to install push-on or mechanical pipejoints with a slight axial “gap” (1/8”-1/4”) between the spigot and the back of thesocket, and with the pipe sections firmly strapped to shaped pier supports locatedimmediately behind the pipe bells as indicated. This is appropriate for normal antici-pated thermal expansion and contraction of individual pipe sections and is easy toaccomplish in the field by assembling the joints to metal contact condition and then“backing them out” slightly. Slight rebating deflection (or “wiggling”) of the jointcan produce the desired results, with field marking of the relative position of thespigot to the bell face to gauge results.

5. It is generally recommended that effective lateral restraint (means of assur-ing lateral stability of joints) be provided for the joints of all pipe-on-support installa-tions, particularly in pressure pipelines and in other cases where lateral or columnarforces may exist to deflect joints or to dislodge the pipeline from the supports.Unstabilized, single rod or other hangers may not be desirable for pressure or otherpipelines.

6. Contact AMERICAN where other design factors are a consideration. Systemswhere crossing pipe is subject to axial thrust forces or movements from bends, etc.,long bridge crossings, large or concentrated thermal expansion-contraction effects,pipe-on-rollers, etc., are applications that may involve special design concerns.

7. The piping layouts as per Cases 2-3 consider the possibility of projects withsizable numbers of exact length repetitive pipe “spans.” Where lesser numbers ofspans are involved on candidate projects, it may be practical and more economicalto provide slightly longer “standard spans,” say by furnishing longer laying lengthintermediate flanged pipe (see Sec. 8) in lieu of the 19'-3" lengths depicted in thesecases, etc. Contact AMERICAN if this is necessary or desirable.
