Introduction

Ameron International Water Transmission Group

Bar-Wrapped Concrete Cylinder Pipe

Since introducing the product in 1942, Ameron WTG has supplied more than 6,000 miles of Bar-Wrapped Concrete Cylinder Pipe (CCP) for piping systems throughout the world. CCP combines the strength of steel with the corrosion resistance and durability of concrete.

CCP consists of a steel cylinder lined with concrete or cement mortar, then helically wrapped with a mild steel bar and coated with dense cement mortar. This composite section acts as a unit to resist internal pressures and external loads. An easily assembled watertight joint is provided by using bell and spigot steel joint rings welded to the ends of the cylinder and sealed with a confined round rubber gasket.

CCP is designed and manufactured in accordance with AWWA Standard C303 and AWWA Manual M9, and is normally supplied in standard diameters of 18” to 72” for operating pressures up to 400 psi. Larger diameters and designs for higher operating pressures have been manufactured and successfully installed.

Welded Steel Pipe

Ameron WTG has supplied more than 5,000 miles of Welded Steel Pipe (WSP) in diameters ranging from 18” to 144”, thicknesses up to 1.25” and for operating pressures up to 500 psi. WSP is manufactured from steel coils formed helically and welded into cylinders or from steel plate that is rolled and longitudinally welded into cylinders. The cylinders are typically lined with cement mortar or lined with epoxy as needed for special applications. Coatings for WSP include cement mortar, polyethylene tape, epoxy, or polyurethane. Joint configurations for WSP include gasketed joints using rolled grooves or bell and spigot steel joint rings and welded joints for either lap welds or butt welds. Custom design and fabricated fittings include elbows, tees, wyes, reducers, closures, valve connections, and other appurtenances. WSP is designed and manufactured to meet the requirements of the applicable AWWA, ASTM, and API standards.

Prestressed Concrete Cylinder Pipe

Prestressed Concrete Cylinder Pipe (PCCP) is a rigid pipe designed to take optimum advantage of the tensile strength of steel and of the compressive strength of concrete and corrosion inhibiting properties of concrete.

PCCP consists of a steel cylinder embedded in a concrete core, which is helically wrapped after curing with high-strength, hard-drawn wire. The wire is embedded in thick cement slurry and coated with a dense cement mortar. An easily assembled watertight joint is provided by using bell and spigot steel joint rings welded to the ends of the cylinder and sealed with a confined round rubber gasket.

PCCP is designed and manufactured in accordance with AWWA Standards C301 and C304 and AWWA Manual M9, and is normally supplied in standard diameters of 42” to 156” for operating pressures up to 700 psi.

Reinforced Concrete Cylinder Pipe

Reinforced Concrete Cylinder Pipe (RCCP) consists of a welded steel cylinder with one or more cages of steel reinforcement in a densely compacted concrete wall. RCCP is designed to withstand substantial live and dead loads. An easily assembled watertight joint is provided by using bell and spigot steel joint rings sealed with a confined round rubber gasket. RCCP is manufactured per AWWA C300 in diameters from 42” to 156” typically for operating pressures up to 260 psi. Designs for higher operating pressures have been manufactured and successfully installed.

Reinforced Concrete Pressure Pipe

Reinforced Concrete Pipe

Reinforced Concrete Pipe (RCP) consists of one or more cages of steel reinforcement in a densely compacted concrete wall. RCP is designed to withstand substantial live and dead loads. It is manufactured in diameters to suit various applications and wide ranges of D-load requirements. An easily assembled watertight joint is provided by a joint formed in the concrete sealed with a confined round rubber gasket. RCP is used for gravity flow applications such as storm drains and sewer lines. RCP is manufactured in diameters from 42” to 156” per ASTM C76 or C361.

Reinforced Concrete Pressure Pipe (RCPP) consists of one or more cages of steel reinforcement in a densely compacted concrete wall that is designed to withstand substantial live and dead loads. An easily assembled watertight joint is provided by a joint formed in the concrete or by using bell and spigot steel joint rings sealed with a confined round rubber gasket. RCPP is manufactured per ASTM C361 or AWWA C302 in diameters from 42” to 156” for operating pressures up to 55 psi.

PressureCast Steel Pipe

PressureCast Steel Pipe can be manufactured in diameters ranging from 24” to 156” for operating pressures up to 500 psi.

PCSP is manufactured from steel coils formed helically and welded into cylinders with the ends prepared for rubber gasket joints. Concrete or mortar lining is placed in the cylinder and pressurized before the concrete is cured. The pressure expands the cylinder to a stress below the steel’s yield point. After the lining is cured, the pressure is released, allowing the cylinder to compress the lining. The steel cylinder remains in tension after all creep and shrinkage of the lining has occurred. The exterior of the cylinder can be coated with cement mortar, polyethylene tape, epoxy, or polyurethane as appropriate for the pipe service application.

The PCSP is a patented, proprietary pipe produced only by Ameron. It is designed to optimize use of high strength steel while still maintaining traditional steel pipe safety factors and the long corrosion performance of concrete or mortar lining.

Steel Pipe Pilings

Bearing piles are required when the shallow soils are not strong enough to support a structure. Tall structures, for example, often require deep foundations based on engineering principles. A deep foundation system must be designed to transfer the loads down through the piles to obtain the load resistance. Steel pipe piles provide both skin friction and point bearing resistance. For non-cohesive soils, pipe piles generate most of their bearing capacity from skin friction. Other soil conditions allow pipe piles to transfer large loads to the point of the pile.

Steel pipe piles are manufactured per ASTM A252 from steel coils formed helically and welded into cylinders or from steel plate that is rolled and longitudinally welded into cylinders. Pipe piles range in size from 18” to 156” in diameter thicknesses up to 3” and can be easily welded together to create piles hundreds of feet in length.

Trenchless Technologies

Trenchless technologies are required to cross beneath major facilities or obstructions such as railways, highways, airport runways, mountains and rivers or to avoid disrupting traffic on city streets. The two primary methods used are tunneling and direct jacking. Tunneling includes installation of a liner or casing with the carrier pipe being placed inside. Direct jacking is where the pipe is pushed into the tunnel as it is excavated. Another trenchless technology is the pipe rehabilitation of existing pipelines.

Various types of pipe can be used for trenchless applications depending on the pipe service requirements. These include:

• Welded Steel Pipe per AWWA C200• Reinforced Concrete Cylinder Pipe per AWWA C300• Prestressed Concrete Cylinder Pipe per AWWA C301• Reinforced Concrete Pressure Pipe per AWWA C302• Bar-Wrapped Concrete Cylinder Pipe per AWWA C303• Reinforced Concrete Pipe per ASTM C76

One method of pipeline rehabilitation is accomplished with steel liners being installed inside existing pipe. These liners are either full cylinders lined with cement mortar or split cylinders. The full cylinders are lined with cement mortar at the plant. The split cylinders are placed inside host pipe, expanded, and then welded. Both types have the annular space between the host pipe and the cylinder fill with grout. The split cylinder type is then lined with cement mortar in the field.

Specialty Fabrication

Fittings required for pipeline projects are designed by our engineering staff to meet the requirements of the project and the applicable standards. Fittings fabricated at our manufacturing facilities include customized wyes, tees, elbows, closures, flanged joints, and other special pipe fittings.
