Chapter 5: Design Methodology - Plastics Pipe Institute

CHAPTER 5: DESIGN METHODOLOGY Overview of Structural Considerations All pipe, whether flexible or rigid, relies on the backfill structure to transfer loads into the bedding. As a result, all pipe also must be installed as designed to perform as expected. This chapter sets forth the design methodology for corrugated polyethylene pipe

Minimum Cover Heights for Corrugated Plastic Pipe Under

Corrugated plastic pipes are referenced by the inside diameter (also called the pipe size, e.g., 24-inch pipe). Unlike the cor­ rugated metal pipe industry, the manufacturers of corrugated plastic pipe do not employ a standardized set of corrugated shapes for each pipe diameter. Rather, a typical plastic pipe

the most aitious research project ever attempted by the plastic pipe industry. A total of 576’ (175 m) of 24” (600 mm) corrugated HDPE pipe (both standard singlewall and N-12 pipe) were buried at depths exceeding 10’ (30 m) in an eankment under Interstate 279 near Pittsburgh.

Manning’s n value for new concrete pipe is 0.010 – 0.009. The concrete pipe industry promotes the use of 0.012 – 0.013 as appropriate long-term values. This 20-30% difference accounts for a long-term deterioration in "n" value due to corrosion and abrasion. The reduction in flow capacity is anticipated, particularly in hostile environments.
