Strong resistance to external pressure: The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipeline, thereby enhancing the resistance of the pipeline to soil loads. The performance of HDP giant double-wall corrugated pipe is better than other pipes.
Low project cost: Under the same load conditions, HDPE double-wall corrugated pipes in the PE water supply pipe production line only need thinner pipe walls to meet the requirements. As a result, compared with solid-wall pipes of the same material specifications, it saves about half of the raw materials, so the cost of HDPE double-wall corrugated pipes is also lower. This is another outstanding feature of the pipeline.
Simple structure: HDPE double-wall corrugated pipe is light in weight, easy to operate and connect, fast in construction, and simple in maintenance. In the tight schedule and construction, its advantages are more obvious under harsh conditions.
Low friction coefficient and large flow: HDPE double-wall corrugated pipe made of HDPE can pass more flow than other diameter pipes. In other words, a relatively small diameter HDPE double-wall corrugated pipe can be used with the same flow rate requirements.
Good low temperature resistance and impact resistance; The embrittlement temperature of HDPE double-wall corrugated pipe is -70℃. Under normal circumstances, construction at low temperature (above -30°C) does not require special protective measures, and construction in winter is convenient. HDPE double-wall corrugated pipe has good impact resistance.
Good chemical stability: HDPE molecules have excellent chemical stability due to lack. Except for a few strong oxidants, most chemical media have no destructive effect on them. Generally speaking, the use of soil, electricity, acid and alkali factors in the environment will not damage the pipeline, will not breed bacteria, will not scale, and its circulation area will not decrease with the increase of operating time.
