Our PE Water Pipe for Agricultural Drip Irrigation Main Line is a professional piping product specially designed for agricultural drip irrigation system operation, engineered to adapt to the low-pressure, high-flow, and uniform water distribution requirements of drip irrigation. Mainly made of PE80/PE100 grade high-density polyethylene (HDPE) (small diameters use medium-density polyethylene (MDPE)), this pipe is the "main artery" of the drip irrigation system, responsible for transporting pressurized water from water sources (reservoirs, pumping stations) to field branch and lateral pipes. It features UV resistance, anti-aging, and excellent corrosion resistance, adapting to harsh agricultural field environments, and realizes precise water and fertilizer integration. With light weight, easy installation, and high cost-effectiveness, it is the core component for water-saving irrigation in modern agriculture, saving more than 60% of water compared to traditional flood irrigation and meeting the needs of green agricultural development.

The pipe has stable ring stiffness and pressure resistance, with minimal pressure loss during water transport. It ensures consistent water pressure in branch pipes across different irrigation areas, avoiding the problem of uneven water output from drippers, and perfectly matches the drip irrigation core requirement of precise irrigation and integrated water and fertilizer management.
It resists erosion by soil acid-alkaline substances, fertilizer, and pesticide residues, with no electrochemical corrosion for buried installation (no anti-corrosion treatment needed). The UV-resistant outer wall prevents cracking and embrittlement after more than 5 years of outdoor exposure, and it has excellent low-temperature impact resistance (-20℃), suitable for buried installation in northern frozen soil areas.
With an elongation at break of ≥300%, the pipe can be bent and laid freely, adapting to complex agricultural terrains such as hills, slopes, and terraces without additional support structures. Coiled pipes enable long-distance laying, reducing the number of field joints and the risk of water leakage, further improving irrigation water use efficiency.
Weighing only 1/8 of steel pipes and 1/10 of concrete pipes, it can be manually handled and laid without large lifting equipment, even operable by farmers without professional skills, significantly shortening project installation time. The buried service life reaches 15–20 years; the smooth inner wall prevents scaling, requiring only joint seal checks, with almost negligible subsequent maintenance costs.
This agricultural drip irrigation main line PE pipe is the core piping for modern water-saving irrigation, applicable to various agricultural planting scenarios: large-scale field crop drip irrigation (wheat, corn, cotton, soybean) for farmland over 10,000 mu; precision irrigation of cash crops (vegetables, fruits, flowers, medicinal herbs) matching fertigation equipment for root delivery of water and fertilizer; greenhouse and facility agriculture irrigation (strawberry, tomato, cucumber) with flexible coiled pipe laying and automated irrigation matching solenoid valves; orchard drip irrigation (apple, citrus, grape) for underground/above-ground laying along orchard roads to avoid soil compaction; and saline-alkali land improvement irrigation, utilizing corrosion resistance to realize salt leaching and alkali removal through precise water delivery.
We adopt food-grade PE raw materials for pipe production, ensuring non-toxic and odorless performance that will not pollute irrigation water and crop growth. For different agricultural irrigation project needs (irrigation area, terrain, crop type), we provide customized solutions, including customized pipe diameters, pressure ratings, coil/straight pipe forms, and matching connection accessories. All products undergo strict pressure loss and anti-aging performance tests, with stable quality to ensure long-term reliable operation of the drip irrigation system. We also provide on-site installation guidance for large-scale farmland projects to solve practical construction problems.
A: The 50mm–110mm diameter is the mainstream specification for large-scale field drip irrigation, which can balance water flow and pressure stability to meet the irrigation needs of large contiguous farmland.
A: Rubber ring socket connection is the best choice for greenhouses, as it features convenient assembly and disassembly, adapting to the seasonal installation and disassembly needs of greenhouse irrigation systems.
A: Yes, it has excellent corrosion resistance to fertilizer solutions, and the smooth inner wall prevents fertilizer residue accumulation and clogging, making it an ideal choice for integrated water and fertilizer transportation in agricultural drip irrigation.
