HDPE Corrugated Pipe — Techduto NBR

The NBR-lined HDPE pipe eliminates corrosion, withstands impacts of up to 750 N, and has a service life of over 75 years. Metal pipes corrode in aggressive soils and require constant maintenance. Installation of HDPE pipes is 35% faster.

Yes — it is one of our largest applications. The special UV and AC lines are already installed at dozens of plants in Brazil, Chile, Argentina, and Mexico, protecting cables with sun and flame resistance far beyond the standard pipe.

It does, but only a minimal amount — just enough to protect the pipe during transport and construction, until it is buried. That protection was not designed for years of direct sun exposure. At solar plants, where the pipe spends its service life exposed in the shaded areas under the trackers, use the UV line, with a reinforced additive formulated exactly for that.

The NBR line complies with standard 15715 and is robust for buried use. The UV line has an extra layer of anti-UV additive for prolonged sun exposure. The AC line carries a certified flame-retardant additive, for environments where fire safety is critical. UV and AC were developed specifically for photovoltaic plants.

Yes. The corrugated conduit protects fiber-optic, telecommunications, and electrical cables. The integrated cable guide (for sizes 40 mm and larger) makes it easier to feed cables through during installation.

The product line ranges from 20 mm to 250 mm, available in coils or bars depending on the diameter. Sizes ranging from 5/8 inch to 10 inches cater to everything from residential installations to large-scale infrastructure projects.

Yes, starting at a diameter of 40 mm, all pipes come with a factory-installed cable guide, making it easy to thread cables through without the need for special tools.

The product complies with ABNT NBR 15715, which specifies requirements for dimensions, impact resistance (up to 750 N), and quality for HDPE corrugated conduits intended for cable protection.
