HP Storm from Advanced Drainage Systems is a high-performance polypropylene pipe for gravity-flow storm drainage applications. It is ideal for when premium joint performance and/or greater pipe stiffness is required, as it couples advanced polypropylene resin technology with a dual-wall profile design for performance and durability. The smooth interior wall offers additional strength as well as high flow. It has an extended bell that adds an additional factor of safety within each joint. It meets or exceeds typical standards for pipe stiffness and joint integrity and meets ASTM F2881 and AASHTO M330 for the respective diameters. It is approved for use by the Army Corps of Engineers, Federal Aviation Authority, and American Railway Engineering and Maintenance-of-Way Association. 800/821-6710; www.ads-pipe.com.
