HDPE double-wall corrugated is formed by high-density polyethylene end through a simultaneous extrusion of the corrugated outer wall and a smooth inner wall. In addition to the ordinary corrosion resistance, high insulation, smooth inner wall and low flow resistance, it has excellent ring stiffness and good strength and toughness due to the special hollow ring structure. Light weight, strong impact resistance and easy to break. At present, it has been widely used in many leading cities in developed countries, especially in the United States, Canada, and many European countries. Double-wall corrugated pipes are widely used in municipal drainage and sewage drainage, agricultural irrigation coal mine ventilation and chemical engineering, and communication cable sheathing. Practice has proved that under the same strength and stiffness requirements, the double corrugation can save 30%-50% of materials compared with ordinary plastics, and the transportation and installation are convenient, which reduces the labor intensity of the construction workers and reduces the total investment of the project. It is an ideal replacement for concrete pipes and cast iron.
Product Features:
1: Unique structure, high strength, pressure and impact resistance: smooth inside, small friction and large flow: convenient connection, good joint sealing, no leakage;
2: Light weight, fast construction, low operating cost and low cost;
3: Polyethylene end belongs to carbon ammonia polymer, the molecule is non-polar, resistant to acid and alkali corrosion; buried service life is more than 50 years; raw material is green environmental protection material, non-toxic, non-corrosive, non-scaling, recyclable;
4: Applicable temperature range is wide - the pipe is not broken in the environment of 60"C, and the maximum temperature of the conveying medium is 60C;
5: Good rapid crack propagation resistance, high stress crack resistance and low scratch sensitivity;
6: High toughness pipe, the elongation at break exceeds 500%, and the adaptability to the uneven settlement of the pipe base is strong; if the soil quality is good, the foundation is not required.
