ENGINEERED SOLUTIONS A-2000™ PVC Pipe for Storm Sewers and Drainage PIPE SOLUTIONS

Drainage systems are required to meet multiple criteria. The choice of a particular material depends upon a number of factors; however, the best choice is the one that yields the best performance over the project life cycle. Thermoplastic Storm Sewer and Drainage Pipe In recent years, the use of thermoplastic pipe for stormwater drainage systems has gained wide acceptance-based upon performance and economic advantages when contrasted with more conventional drainage pipe materials. However, when it comes to performance, not all thermoplastic storm sewer pipes are equal. There are distinct...

When selecting a system based on pipe stiffness, material strengthand structural capability, A-2000 PVC far exceeds the performance characteristics of HDPE drainage pipe. A-2000 PVC pipe can be used with 1 foot of cover under highway loading. Current AASHTO LRFD Design Methodology has required all thermoplastic pipes to have a minimum height of cover of 2 feet under pavement. This requirement was derived from a Minnesota DOT Research Report (2005) that studied HDPE pipe performance under highway loading. The report indicates significant thermal expansion of HDPE pipe under shallow fills....

Durability, Service Life PVC materials used in the manufacture of gravity flow pipe offer excellent resistance to conventional corrosion and abrasion. In fact, profile wall PVC pipe has been shown to have better abrasion resistance than reinforced concrete pipe in side-by-side laboratory testing at California State University. PVC and HDPE do not provide equal long-term durability performance. Under loading or localized tensile stress, some grades of HDPE are subject to environmental stress cracking—also known as slow crack growth. Exhibited as premature rupture, this phenomenon can occur...

Hydraulic Efficiency A-2000 vs. Concrete Pipe Thermoplastic pipes, with smoother interiors and fewer joints, reduce resistance to flow and are hydraulically more efficient than conventional (i.e., RCP) storm drainage pipe materials. Flow testing conducted in 2002 by the Utah Water Research Laboratory concluded A-2000 PVC Pipe, with its inner wall formed over a polished mandrel, has the lowest wall friction factor (Manning’s “n” = .009) of any thermoplastic pipe available and offers real advantages compared to RCP (n = .012- .013). This added efficiency means A-2000 can be designed as a...

Best Pipe on the Planet The Need for Tight Joints Storm sewers have always presented special needs for tight jointing systems. Because of their function, they are subject to rapidly changing flow levels. The sudden rise and fall of flow levels leaves storm sewers susceptible to backfill migration into the sewer unless tight joints are used. This loss of backfill reduces the soil support of the pipe and causes settlement at the surface. Where storm sewers are below the existing water table, water tight joints are needed to prevent infiltration and maintain storm sewer capacity. A-2000’s easy...
