Description

Technical Field

[0001] The utility model relates to the technical field of farmland irrigation, in particular to a HDPE corrugated pipe for farmland irrigation. Background Art

[0002] High-density polyethylene (HDPE) is a highly crystalline, non-polar thermoplastic resin. Its appearance in its original form is milky white, with a degree of translucency in thin cross-sections. PE exhibits excellent resistance to most household and industrial chemicals, though some chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance, making it suitable for packaging applications. HDPE has excellent electrical properties, particularly high dielectric strength, making it well-suited for wire and cable. Medium to high molecular weight grades offer excellent impact resistance, even at room temperature and as low as 40°F. HDPE pipe represents an alternative to traditional steel pipes and polyvinyl chloride drinking water pipes. Current HDPE corrugated pipes used for farmland irrigation often suffer from difficulties connecting different pipes and weak joints. To address this issue, we propose a new HDPE corrugated pipe for farmland irrigation. Utility Model Content
