Corrugated High Density Polyethylene (HDPE) Pipe represents a significant advancement in modern drainage and fluid management systems. Engineered for superior performance, these pipes offer exceptional durability, chemical resistance, and a long service life, making them an ideal choice for a wide range of applications from agricultural and residential drainage to large-scale civil and environmental projects.
The inherent properties of HDPE material, combined with a corrugated design, create a pipe solution that outperforms traditional materials like concrete or PVC. Below are the primary features that define its performance.
Our corrugated HDPE pipes are manufactured to meet or exceed industry standards, including AASHTO M294 and ASTM F2306. The following tables detail the standard specifications for our most common product lines.

The joining system for corrugated HDPE pipe is typically achieved with snap-on couplers or bell-and-spigot joints with integral gaskets, providing a water-tight seal that is easy to install without specialized tools. For specific project requirements, custom fittings including tees, elbows, and wyes are readily available.
