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.
Pipes are manufactured of ductile iron, grade 60-42-10, (minimum tensile strength: 60,000 psi; minimum yield strength: 42,000 psi; minimum elongation: 10%) in accordance with AWWA C151.
Flanges and static-cast MJ bells can be tapped for studs when specified by the purchaser.
All pressure ratings shown are AMERICAN’s suggested standard and are for water service.
AMERICAN furnishes one fabricated thrust/water stop collar design with 360° fillet welds on both sides of the collar. This pipe collar can effectively and interchangeably be used for both thrust collar and water stop applications.
Unless otherwise noted, all cast-on flanges are per AWWA C110 or C153, and all threaded-on flanges are per AWWA C115.
All mechanical joints comply with AWWA C111. Threaded-on or otherwise fabricated MJ bells are per applicable portions of AWWA C115 and C153. Weights of MJ accessories are not included in weights of fittings with MJ outlets shown in tables, unless otherwise specified.
