Centrifugally cast wall pipe is manufactured for use in piping water through walls in water treatment plants and pump stations.
All AMERICAN fabricated wall pipe uses ductile iron components in combination with the following: cast or threaded on mechanical joint bells (can be tapped for studs), flanges (can be tapped for studs) and welded-on collars.
Wall pipe is normally fabricated of special thickness class 53 ductile iron pipe, but it may be furnished with minimum classes unless threaded flanges or threaded mechanical joint bells are included or unless specified otherwise.
Wall pipes with centrifugally cast mechanical joint bells will be provided instead with heavy-duty steel key locking thread inserts to accept threaded studs.
Flanges and mechanical joint bells of minimum-length pieces should normally be specified by the purchaser as “tapped for studs” to enable assembly of joints flush with the wall face.
Minimum-length pipes with plain ends in many cases do not allow enough room between the plain end and the collar to assemble joints. Consult AMERICAN for plain end joint assembly needs, which normally require longer pipes.

1.) Laying lengths are rounded to the nearest 1/4".
Maximum laying length of below wall pipe is 19’-6" (except 19’-0" for 64"), except for MJ–T/C–PE or Fst–T/C–PE, which may be furnished in full 20-ft nominal length.
4"-16" Flange–T/C–Flange and Flange–T/C–PE pipe may also be furnished up to 20’-0" length. Contact AMERICAN if longer lengths are required. All intermediate lengths can be furnished.
Thrust Collars may not be located in exact center of all minimum-length pieces shown above.
Flanges and mechanical joint bells of minimum-length pieces should normally be specified by the purchaser as “tapped for studs” to enable assembly of joints flush with the wall face.
Wall pipe lengths shorter than those shown here can be furnished in some sizes by special fabrication. Contact AMERICAN for details.
Overall lengths are subject to manufacturing tolerances. If maximum overall length is critical, such as for installation of an item inside steel forms, this must be specified by the purchaser on the order.
Correctly installed flanged wall pipe will normally have the bolt holes straddling the horizontal and vertical centerlines. Checking with a spirit level or plumb line prior to pouring the walls is recommended.
Wall pipe with MJ threaded–on bells (MJ Fab), Flex–Ring, and Lok–Ring bells can also be furnished. Contact AMERICAN for dimensions not shown above.
Minimum–length pipes with plain ends (PE) in many cases do not allow enough room between PE and collar to assemble joints. Contact AMERICAN for PE joint assembly needs, normally requiring longer pipes.
