Convenient construction:double-wall corrugated pipe

Because of the light weight of the HDPE double wall corrugated pipe, the handling and connection are convenient, so the construction is quick and easy to maintain. During the construction period under conditions of poor condition, the advantages are more obvious.double-wall corrugated pipe

The friction coefficient is small and the flow is largedouble-wall corrugated pipe

HDPE double wall corrugated pipe with HDPE can be used more than other pipes of the same caliber. In other words, with the same traffic requirements, the relatively small HDPE double wall corrugated pipe can be used.

Low temperature resistance to shock resistancedouble-wall corrugated pipe

Because HDPE molecules have no polarity, the chemical stability is excellent. In addition to a few strong oxidants, most of the chemical agents do not damage it. Generally, soil, electricity, and acid and alkali elements of the environment will not destroy the pipe, not breeding bacteria, not scaling, and its circulation area will not decrease with the increase of running time.double-wall corrugated pipe

Long service lifedouble-wall corrugated pipe

The use of the double wall bellows of HDPE can be up to 50 years in the light of sunlight.
