Frequently Asked Questions
What is TDR ULTRA® SW pipe used for?
TDR ULTRA® SW is an HDPE single wall pipe (Flex Series) for gravity-flow, subsurface irrigation, highway, and land drainage. It is available in 3-inch through 6-inch diameters.
What is HDPE single wall pipe used for?
HDPE single wall pipe is a flexible, coiled corrugated pipe used for subsurface and agricultural drainage, land drainage, and edge drains. TDR ULTRA® SW is an HDPE single wall pipe built for these applications in 3-inch through 6-inch sizes.
What pipe is best for subsurface or agricultural drainage?
For subsurface and agricultural drainage, HDPE single wall pipe is a common choice because it is lightweight, flexible, and supplied in long coils. TDR ULTRA® SW is an HDPE single wall pipe offered perforated for collecting water or solid for conveying it.
What is the difference between single wall and dual wall HDPE pipe?
HDPE single wall pipe like TDR ULTRA® SW is corrugated throughout and coiled, ideal for subsurface and agricultural drainage in 3–6 inch sizes. Dual-wall pipe like TDR ULTRA® adds a smooth interior liner for higher flow and watertight joints, used for storm and gravity drainage in 4–60 inch sizes.
What sizes does TDR ULTRA® SW come in?
TDR ULTRA® SW HDPE single wall pipe is available in 3-inch, 4-inch, and 6-inch (75–150 mm) diameters, supplied in coils.
What standards does TDR ULTRA® SW meet?
TDR ULTRA® SW meets AASHTO M252 and ASTM F667, with HDPE compound 435420C per ASTM D3350. Optional geotextile fabric meets ASTM D6707.
Is TDR ULTRA® SW available perforated?
Yes. TDR ULTRA® SW comes in perforated (Type CP, Class 2) or non-perforated configurations, and can be wrapped with geotextile fabric for filtration.
How is TDR ULTRA® SW joined?
It is a coiled, plain-end HDPE single wall pipe joined with a soil-tight split or snap coupler, with a minimum pipe stiffness of 24 psi (170 kPa).
