In modern agricultural production, a scientific and reasonable drainage system is essential to increase crop yields, prevent soil salinization, and reduce waterlogging disasters. HDPE (high-density polyethylene) pipes have become the preferred material for agricultural drainage systems due to their excellent performance and long life. This article will comprehensively introduce the advantages, technical characteristics and applications of HDPE pipe for agricultural drainage in the agricultural field.
1. Excellent corrosion resistance
Completely resist the erosion of fertilizers, pesticides, and soil acid and alkali
Will not rust or scale like metal pipes
Service life of more than 50 years, greatly reducing the frequency of replacement
2. Excellent physical properties
Strong impact resistance, can withstand agricultural machinery rolling
Good flexibility, can adapt to foundation settlement
Light weight (only 1/8 of steel pipes), easy to transport and install
3. Efficient drainage capacity
Smooth inner wall, low friction coefficient (0.009), drainage efficiency is 30% higher than concrete pipes
Perforated design can be used to achieve uniform infiltration and drainage
1. Open ditch drainage system
Replaces traditional concrete ditches
Fast installation speed, 40% lower construction cost
Can be laid in a curved manner to adapt to complex terrain
2. Concealed pipe drainage system
Underground burial depth 0.8-1.5 meters
Effectively control groundwater level and prevent soil salinization
Use with geotextile to prevent silt blockage
3. Greenhouse drainage
Anti-ultraviolet formula suitable for outdoor use
Can be made into an infiltration irrigation system to achieve water and fertilizer integration

1. Pipe diameter selection: According to the drainage demand, it is recommended to use a 200-400mm pipe diameter for general farmland
2. Burial depth design: Consider the depth of the frozen soil layer and the thickness of the tillage layer
3. Slope control: Maintain a slope of 0.5%-1% to ensure gravity drainage
4. Filtration protection: Wrap geotextile around the pipe to prevent clogging
HDPE drainage pipes are rapidly replacing traditional drainage materials in the global agricultural field due to their durability, economy and ease of construction. With the advancement of high-standard farmland construction in my country, HDPE pipe for agricultural drainage will become an important part of modern agricultural infrastructure. Choosing high-quality HDPE drainage pipes is to provide long-term and reliable protection for farmland water conservancy construction.
