In addition to the good corrosion resistance, high insulation, smooth inner wall and low flow resistance of ordinary plastic pipes, HDPE double-wall corrugated pipes also have a special hollow ring structure, which has excellent ring stiffness and good Strength and toughness, light weight, strong impact resistance, and not easy to break. At present, it has been widely used in many fields in developed countries, especially in the United States, Canada, Japan and many European countries. Double-wall corrugated pipes are widely used in municipal drainage and sewage, agricultural irrigation, coal mine ventilation, chemical industry, communication cable sheathing and other fields. Practice has proved that the use of double-wall corrugated structure can save materials by 30%-50% under the requirements of engineering application strength and height. In addition, compared with concrete pipes and cast iron pipes, it is convenient to transport and install, which reduces the labor intensity of construction personnel and reduces The total project investment and other advantages are ideal replacement products for concrete pipes and cast iron pipes.
