HDPE double-wall corrugated pipe, also known as PE corrugated pipe, has an outer layer typically made of high-density polyethylene (HDPE) and an inner layer made of corrosion-resistant materials such as metal or special plastics. The space between these two layers is corrugated, which is also the reason for its name. Compared to traditional concrete pipes and cast iron pipelines, HDPE double-wall corrugated pipes are very lightweight, have excellent chemical and physical properties, and are very convenient to connect with simple construction. It mainly has the following major advantages: 1. Strong compressive strength; due to its unique structure, HDPE pipes have strong compressive strength and impact resistance. 2. Good flexibility; this means that HDPE double-wall corrugated pipes can adapt to uneven soil settlement environments, have low requirements for construction conditions, and can be laid in non-straight trenches. 3. Smooth inner wall; easy for liquid transportation with a large flow capacity, reducing transport pressure. 4. Lightweight; easy to transport and construct, which also means lower construction costs and shorter construction periods. 5. Better wear resistance; German experiments have shown that HDPE pipes have 3-5 times better wear resistance than ordinary or fine-grained steel pipes when transporting fluids at a speed of 15 feet per second. 6. Convenient connections; zero leakage at joints, corrosion-resistant, good sealing properties, no scaling occurs, avoiding secondary pollution of water quality during transportation without worrying about the flow area being reduced due to scaling issues. 7. Long lifespan; the service life exceeds that of traditional steel pipes and can reach over 50 years under conditions without strong ultraviolet exposure. 8. Stable chemical properties; because HDPE molecules are non-polar, most chemical media will not damage it except for a few strong oxidizers. Under normal environmental conditions such as electricity, soil, and conventional acids and bases will not damage HDPE double-wall corrugated pipes and are less likely to breed bacteria. 9. Low-temperature resistance; the embrittlement temperature of HDPE double-wall corrugated pipes is -70°C, so there is no need for special protective measures during construction under general low-temperature conditions (above -30°C), making winter construction convenient.

It mainly has the following major advantages:
1. Strong compressive strength; due to its unique structure, HDPE pipes have strong compressive strength and impact resistance.
2. Good flexibility; this means that HDPE double-wall corrugated pipes can adapt to uneven soil settlement environments, have low requirements for construction conditions, and can be laid in non-straight trenches.
3. Smooth inner wall; easy for liquid transportation with a large flow rate, reducing transport pressure.
4. Lightweight; convenient for transportation and construction, which also means lower construction costs and shorter construction periods.
5. Better wear resistance; German experiments have shown that HDPE pipes have wear resistance that is 3 to 5 times higher than ordinary or fine-grained steel pipes when transporting fluids at a speed of 15 feet per second.

Under normal environmental conditions such as electricity, soil, and conventional acids and bases will not damage HDPE double-wall corrugated pipes, making it less prone to bacterial growth.
9. Low-temperature resistance; the embrittlement temperature of HDPE double-wall corrugated pipes is -70℃; generally under low-temperature conditions (above -30℃), no special protective measures are needed during construction in winter.
