ADS N-12 HP PIPE CONTINUES TO ADD INDUSTRY APPROVALS


HILLIARD, Ohio - ADS' N-12® HP Corrugated Storm Pipe complies with recently published AASHTO MP21-11 standard for polypropylene pipe in surface and subsurface drainage applications. It offers enhanced stiffness over traditional storm sewer products, provides increased longitudinal beam strength, and superior chemical and abrasion resistance.

HILLIARD, Ohio – (September 21, 2011) – Advanced Drainage Systems, Inc. (ADS), announced today that its N-12® HP Corrugated Storm Pipe complies with recently published AASHTO MP21-11 standard for polypropylene pipe in surface and subsurface drainage applications. N-12 High Performance 12-inch through 60-inch dual and triple wall corrugated pipe meets or exceeds this new national specification. Both public and private specifying agencies rely on the American Association of State Highway and Transportation Officials (AASHTO) for product specification standards, including pipe for use in transportation infrastructure projects.

"AASHTO specifications represent the culmination of extensive work by key department of transportation officials who make up AASHTO's Subcommittee on Materials," stated Ryan Zenkewicz, HP Storm Market Manager. "This latest recognition completes a strong foundation of specifications that include those from ASTM and CSA for this premium product. This particular specification highlights the need for products in high performance storm sewer applications. “N-12 HP pipe is manufactured from an engineered grade of polypropylene resin and is designed for installations with less than ideal conditions and still reduce costs."

The N-12 HP adds to ADS' broad line of product selection for storm water projects. This product offers enhanced stiffness over traditional storm sewer products, provides increased longitudinal beam strength, and superior chemical and abrasion resistance.

The pipe is manufactured from impact modified co-polymer polypropylene resin. The N-12 HP's smooth interior wall promotes excellent flow rates while its corrugated structure maximizes stiffness and strength. All N-12 HP pipe diameters feature a polymer reinforcement extended bell and spigot with dual gaskets for maximum joint integrity. The pipe is available in 20-foot (6m) and 13-foot (3.9m) lengths to accommodate various trench box dimensions.

A complete line of fittings, taps and manhole connections are available from ADS. For additional information call ADS at (800) 821-6710, go to www.ads-pipe.com or contact any local ADS office.
