Is HDPE double wall corrugated pipe UV resistant?

2025-05-05

In municipal drainage, communication cable protection and other projects, HDPE double-wall corrugated pipe is widely used due to its excellent performance. However, many people have questions about its durability in outdoor environments: Is HDPE double-wall corrugated pipe resistant to ultraviolet rays? After all, if the pipe is exposed to sunlight for a long time, if it cannot resist the invasion of ultraviolet rays, it will directly affect its service life and engineering safety.

HDPE (high density polyethylene) itself is easily damaged by ultraviolet rays when exposed outdoors. Ultraviolet rays have high energy and can break the molecular chain of HDPE, causing the material to age, become brittle, and reduce mechanical properties. But modern production processes give HDPE double-wall corrugated pipes good UV resistance by adding special additives, the key ingredient of which is UV absorbers.

Take benzotriazole UV absorbers as an example, it is like the "sun protection guard" of HDPE double-wall corrugated pipes. This type of absorber can keenly capture ultraviolet rays, absorb ultraviolet energy, and release it into the surrounding environment in the form of heat energy, so as to avoid the direct action of ultraviolet rays on the HDPE molecular chain and prevent the molecular chain from being broken. In this way, the aging rate of HDPE double-wall corrugated pipes is greatly delayed, and even under direct sunlight for a long time, it can maintain good physical properties and structural stability.

practical application case can more intuitively reflect the anti-ultraviolet effect of HDPE double-wall corrugated pipe. In a municipal drainage project in a southern city, HDPE double-wall corrugated pipe with UV absorber is used. After 5 years of outdoor use, after professional testing, the key indicators such as ring stiffness and tensile strength of the pipe are reduced within a reasonable range, and it can still meet the drainage needs; while the control pipe without UV absorber has appeared obvious embrittlement and cracking in only 2 years.
