Vianini Pipe, Inc. was
established in 1968 on a 67 acre site in Readington Township,
New Jersey. There are two principal manufacturing facilities
at this location: the first produces Reinforced Concrete
Pipe(RCP),both round and elliptical; the second produces
primarily Prestressed Concrete Cylinder Pipe(PCCP), Box
Culvert and Jacking or Microtunneling Pipe. Both plants
have all-weather production capabilities with over 110,000
square feet of indoor manufacturing area. While the company's
typical market area is the northeast, Vianini pipe has supplied
pipe throughout the eastern United States including to Florida
by rail and to Puerto Rico by ocean going barges.
When first constructed, the plant was designed to manufacture
only RCP. The RCP produced by Vianini Pipe is generally
used for non-pressure applications, such as culverts and
gravity storm water and sanitary sewer lines. The round
pipe is manufactured in accordance with ASTM C76 in diameters
ranging from 12" through 78". Several joint configurations
are available including slip joint (tongue and groove).
"O" ring rubber gasketed joints and rubber and
steel joints. The latter utilizes steel joint rings, embedded
in each end of the pipe, with one end, the spigot, having
a preformed groove to contain an "O" ring rubber
gasket. This pipe is typically used for applications requiring
low infiltration or exfiltration.
Also manufactured at the RCP facility is elliptical reinforced
concrete pipe. Produced in sizes that have flow characteristic
equivalent to round diameters of 18" through 78",
elliptical RCP is used for the same applications as the
round pipe, but in areas that require shallow trenches or
little clearance with other utilities. Elliptical RCP conforms
to ASTM C507.
Typically, the RCP plant produces 100,000 tons of pipe per
year for projects throughout New York, New Jersey and Pennsylvania.
In 1979 construction of a second plant began on our Readington
Township site to produce prestressed concrete cylinder pipe(PCCP),
manufactured to the AWWA standard C301. A pressure pipe,
PCCP's primary application is water and sanitary sewer force
mains, and it is also used extensively for cooling water
piping in power plants and process piping in water and wastewater
treatment plants, as well as many other applications requiring
a pressure pipe.
Two types of PCCP are manufactured at this plant. Prestressed
concrete lined cylinder pipe(LCP)is produced in diameters
24" through 48", while prestressed concrete embedded
cylinder pipe(ECP) is available up to 144" in diameter.
Both pipe consist of a steel cylinder with steel joint rings
welded to each end, lined or embedded with concrete, then
wrapped with a high tensile wire at a predetermined spacing
and finally coated with a protective layer of mortar.
For LCP, the steel cylinder is lined with concrete by Vianini's
innovative Turbomaster process. Concrete cores manufactured
by this process are free of cracks, voids and surface imperfections.
The core's uniformity, dimensional tolerances and strength
are superior to that required by the AWWA standard.
PCCP is most commonly supplied in 20-foot lengths, although
lengths of up to 40-foot have been used for special applications.
Shorter lengths are produced to maintain a critical point
of intersection, stations, valves or other fitting locations.
One component of Vianini Pipe's PCCP plant is a fully equipped
fitting shop. Here precision crafted fittings such as elbows,
wyes, tees and crosses, reducers and adapters are produced
which allow design engineers to easily alter the straight
course and create layouts to overcome obstacles that would
otherwise require cutting and fitting at the jobsite. All
fittings and specials can be fabricated with a wide range
of ends making it possible to connect to most other types
of pipe and can be customized to virtually any shape or
Another important market that has been pioneered by Vianini
Pipe's Inc. is "Microtunneling" Pipe. The process
of microtunneling is to "jack" the pipe through
the earth from a sending pit to a receiving pit with the
use of heavy jacks and tunneling machinery. Vianini pipe
has provided microtunneling pipe for projects that have
been jacked under active taxiways of major metropolitan
airports. The companies longest single jack has been in
excess of 1500 feet. The microtunneling process is becoming
more common due to the fact that the social costs are smaller
and site disruption are less than the traditional "open"
The company also manufactures box culverts for use in major
drainage projects throughout the northeast. It has made
box culverts with spans as little as 2 1/2 feet and as large
as 15 1/2 feet.
At Vianini Pipe, the products are quality certified. Various
engineering standards require the most rigorous and extensive
quality assurance and in-process inspection of concrete
pipe products. Our experienced inspectors, supported by
our on-site laboratory, have always assured compliance.
In addition, the entire PCCP manufacturing process is manufacturing
is independently audited by third party inspectors (Lloyd's
Register), who certify that Vianini pipe meets or exceeds
the AWWA standards. Vianini Pipe RCP plant is a quality
certified plant of the American Concrete Pipe Association
Vianini Pipe is a member of the American
Water Works Association, American
Concrete Pressure Pipe Association and the American
Concrete Pipe Association. Its employees serve on many
noteworthy committees of these associations.
The company prides itself in having the ability to engineer,
design and produce quality concrete products for any project.
Vianini Pipe, Inc is a Cementir Holding Group Company with operations throughout the world with concentrations in cement, aggregates, and precast products. Its direct parent company is Aalborg Portland A/S.
