Pipe

Civil engineers assisting communities replace or rehabilitate stormwater, wastewater, and potable water systems and designing new systems should be prepared to evaluate and recommend appropriate pipe products for specific applications and site conditions. In response to a request from CE News, companies and associations provided the following information about their products to aid in this process.

Advanced Drainage Systems’ (ADS) MEGA GREEN WT IB pipe, suitable for storm sewers, retention/detention systems, and ditch enclosures, has a minimum recycled content of 40 percent. It is available in diameters from 12 inches to 60 inches. According to ADS, the pipe supports H-25 live loads with 12 inches minimum cover; 60-inch pipe requires 2 feet cover for H-25 loads. The pipe has a built-in bell-and-spigot joint and factory-installed rubber gaskets that meet ASTM F477 requirements.

The American Concrete Pipe Association updated its Concrete Pipe Design Manual for the proper installation of concrete pipe and boxes. The manual helps engineers select the type, size, and strength requirements of pipe. It includes standard installations using the indirect design method. More than 330 pages of tables and figures cover hydraulics of sewers and culverts, live loads and earth loads, supporting strengths, and supplemental design data. While focusing on construction of the pipe/soil system, the manual addresses factors critical to completion of the entire system, from delivery of concrete pipe and boxes to the jobsite to acceptance of the installed sewer or culvert.

CertainTeed Yelomine pipe is made from a modified PVC formulation with increased sunlight and impact resistance. According to the company, that makes it suitable for use in above-ground applications where conventional white pipe may not have the required long-term performance. Its spline-lock joining system holds the pipe together when pressurized. Besides water and sewer bypass lines, CertainTeed says Yelomine is also ideal for mining, irrigation, and trenchless construction applications.

CONTECH Construction Products Inc. offers Ultra Flo corrugated metal storm sewer pipe. According to the company, Ultra Flo, available in galvanized steel, aluminized steel Type 2, or aluminum, has a Manning’s "n" of 0.012, hydraulically equivalent to reinforced concrete pipe but lighter and with a smaller outside diameter for faster and lower-cost installation. Standard 20-foot-long pipe lengths can be joined with CONTECH’s Quick Stab Bell & Spigot joints or Hugger Bands. Factory-made fittings such as manhole risers, catch basin risers, elbows, and reducers also are available.

Freedom Plastics, Inc., expanded its product offering of C900/C905 pressure pipe to include 24-inch-diameter pipe. According to the company, the pressure pipe meets or exceeds all performance specifications of AWWA C-905-97, when tested in accordance with ASTM D-2122. Freedom’s C900/C905 Pure Blue pipe, listed with NSF under Standard 61 for toxicology and health effects, is colored blue for quick in-ground identification as water-main pipe. Freedom Plastics also manufactures AWWA C900 and C905 pressure pipe in Green color for sewer force-mains. Violet color for reclaimed water systems is labeled "Caution—Do Not Drink—Reclaimed Water."

HOBAS Pipe USA’s centrifugally cast pipe features inherent corrosion resistance, high strength-to-weight ratio, and a smooth surface, making it ideal for sewers, wastewater, stormwater, and potable water. According to the company, the fiberglass-reinforced, polymer mortar pipe is suitable for many types of installation, including open cut (direct bury), sliplining, jacking or microtunneling, tunnel lining, and above ground. Push-together, 20-foot joints reduce installation time and costs. Pipe diameters range from 18 to 110 inches for both pressure and gravity applications. HOBAS says its potable water pipes and joint gaskets have been tested and comply with NSF standard 61 for drinking water components.

MATCOR received a patent for its new impressed current cathodic protection system, which, according to the company, prevents corrosion in the interior of larger diameter salt and wastewater metallic pipelines. The system comprises a double-ended, flexible anode assembly that is placed inside a pipeline. Each end of the anode assembly has a pressure-seal fitting where the DC electrical power supply is connected. Once the system is installed and energized, it produces a safe, low-voltage DC electrical current that stops corrosion. Special monitoring devices ensure corrosion is not occurring.

The Uni-Bell PVC Pipe Association’s Handbook of PVC Pipe: Design and Construction is in its fourth edition and contains more than 500 pages of technical information on the design and installation of gasketed PVC pipe for buried water, sanitary, and stormwater drainage systems. The Handbook covers design issues such as external load capability, earth loads, live loads, cyclic strength, hydrostatic strength, chemical resistance, support spacing, and longitudinal bending. One chapter is dedicated to hydraulics, with numerous tables to assist with the design of pressure or non-pressure systems. Another chapter is devoted to recommended installation methods, with an emphasis on proper jointing and embedment.
