AtlanFlow SN8 HDPE Stormwater Pipe

AtlanFlow SN8 HDPE corrugated pipe is a dual wall (corrugated outer wall and smooth inner wall) pipe engineered from high density virgin polyethylene (HDPE).

Light, strong and durable, it requires low cover and is hydraulically efficient with superior performance in gravity-flow drainage applications.

High density Polyethylene Pipe

Durable | Reliable | UV Resistant

Our AtlanFlow SN8 pipes are made from Polyethylene (PE), a polymer known for its high strength-to-weight ratio, excellent temperature performance, and impact resistance. PE’s chemical resistance makes it ideal for environments exposed to corrosive substances.

Widely used in industries like construction, automotive, packaging, and agriculture, PE is particularly valued in infrastructure for pipes and stormwater systems due to its corrosion resistance, flexibility, and efficiency in fluid flow applications.

PE’s recyclability and resistance to UV radiation further enhance its appeal as an environmentally friendly and durable material. Its molecular structure provides stability and protection from sunlight damage, making it a reliable choice for various demanding applications.
