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 size.

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" cut" method.

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 (Q-Cast Certified).

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.
