Description

• Material Ductility and Flexural Modulus The low-density structure of this polyethylene irrigation tubing provides high ductility, allowing the pipe to be maneuvered around obstacles without permanent kinking or structural deformation. This flexibility simplifies the layout of drip irrigation hose pipes in orchards and uneven terrain, significantly reducing the requirement for elbow fittings and specialized installation machinery.
• UV-Stabilized Carbon Black Integration By incorporating 2% to 3% high-grade carbon black into the virgin material, the LDPE drip irrigation pipe gains substantial resistance to photo-oxidation caused by intense solar radiation. This material property prevents the polymer chains from becoming brittle in tropical or arid climates, ensuring the agricultural drip pipe maintains its structural integrity over an operational lifespan of 5 to 10 years depending on environmental conditions.
• Hydraulic Efficiency via Smooth Internal Bore The advanced extrusion process results in a low-friction internal surface that minimizes pressure drop across the drip irrigation main line. This smooth bore discourages the accumulation of mineral deposits and biological film, maintaining consistent flow rates for emitters and reducing the long-term energy requirements of the pumping system.
• Chemical Compatibility for Fertigation Systems The inert chemical properties of LDPE make these pipes highly resistant to the acids, alkalis, and salts commonly used in modern fertigation. This chemical shield allows for the direct delivery of nutrients through the irrigation system without the risk of pipe corrosion or chemical leaching, ensuring a versatile and reliable nutrient delivery mechanism for high-value crops.
• Environmental Stress Crack Resistance (ESCR) Engineered to withstand significant thermal fluctuations, this 16mm/20mm LDPE pipe exhibits high environmental stress crack resistance. This property ensures that the tubing does not fail at connection points or sharp bends when subjected to repeated expansion and contraction cycles, which is critical for projects located in regions with high diurnal temperature variations.
• Standardized Pressure Rating for System Safety With wall thicknesses calibrated to meet PN2.5, PN4, or PN6 ratings, the pipe provides a reliable safety margin for low-pressure water supply tasks. This predictable pressure resistance allows project engineers to design systems that account for surge pressures and external mechanical loads, ensuring the overall safety and reliability of the irrigation network.
• On-Site Customization and Fitting Compatibility The ductile nature of the polyethylene material allows for precise manual punching and the secure insertion of on-line emitters and barbed fittings. This ease of processing enables contractors to customize emitter spacing on-site, facilitating rapid deployment and ensuring leak-free connections in diverse agricultural, greenhouse, and landscaping projects.
• Optimized Logistics and Handling Density Due to the low specific gravity of the material, this LDPE irrigation tubing is lightweight and supplied in high-density rolls, which maximizes container loading capacity. For the procurement manager and contractor, this translates to lower sea-freight costs per meter and significantly reduced labor requirements for offloading and manual field distribution.

Scope of application

• High-Density Orchard and Vineyard ManagementIn large-scale fruit production projects, this LDPE drip irrigation pipe functions as a durable secondary distribution line or lateral for on-line pressure-compensating emitters. The flexible irrigation pipe is specifically engineered to navigate the irregular topography of hill-side orchards and vineyards, carrying raw water or treated irrigation water under standard operating pressures of PN2.5 to PN6. Its high environmental stress crack resistance (ESCR) ensures the system remains operational despite ground movement or thermal expansion in open-field environments.
• Commercial Greenhouse and Protected HorticultureWithin controlled environment agriculture (CEA), this polyethylene irrigation tubing serves as the backbone for precision micro-irrigation and hydroponic systems. It is primarily used for the high-frequency delivery of nutrient solutions—a process known as fertigation—where the medium contains diluted nitrogen, phosphorus, and potassium-based fertilizers. The pipe's inert chemical properties prevent internal degradation when exposed to acidic or alkaline nutrient mixes, ensuring a consistent water supply to high-value vegetable and floral crops.
• Industrial Heap Leaching in Mining OperationsFor mineral extraction projects, particularly in gold and copper mining, this low-density polyethylene pipe is utilized in heap leaching pads for the uniform distribution of chemical solvents. The system typically conveys diluted sulfuric acid or cyanide solutions over vast ore heaps. The material's inherent resistance to aggressive chemical media and high UV stability allows it to maintain structural integrity in harsh, high-altitude or desert mining sites where conventional piping would fail due to chemical embrittlement.
• Municipal Landscaping and Commercial Turf ProjectsThis drip irrigation main line is deployed in urban greening initiatives, including public parks, highway medians, and golf course perimeters. The 16mm/20mm LDPE pipe is used to feed sub-surface or surface irrigation networks, delivering potable or reclaimed water to ornamental plants and turf. Its superior flexibility allows contractors to install the network around existing civil infrastructure, such as curbs and utility lines, without the hydraulic friction losses associated with excessive rigid fittings.
• Open-Field Row Crop ProductionIn extensive farming operations for crops such as sugarcane, cotton, and maize, this agricultural drip pipe acts as a reliable supply conduit for integrated watering systems. It handles the transport of ambient temperature surface water from filtration units to the individual drip tapes or emitters. The lightweight nature of the drip irrigation hose pipe facilitates rapid seasonal deployment and retrieval in mechanized farming environments, offering an economical balance between tensile strength and handling efficiency.
