The type of hose used in agricultural irrigation depends on several factors, including region-specific needs, economic considerations, available materials, and irrigation methods. The following are some of the common types of water pipes used in agricultural irrigation:

1. Plastic pipes: Plastic pipes are very common in agricultural irrigation, especially polyethylene (PE) and polyvinyl chloride (PVC) pipes. They are widely used in many regions due to their anti-corrosion properties, light weight, and easy installation and maintenance. PVC pipes are suitable for low pressure irrigation systems, while PE pipes can be used for higher pressure irrigation systems.

2. Metal pipes: Metal pipes, such as steel or aluminum pipes, are also used for agricultural irrigation in some areas. They are relatively strong, can withstand higher pressure, and are suitable for some large irrigation projects.

3. Concrete pipes: Concrete pipes are used in some agricultural irrigation systems to transport large volumes of water. They are durable but can be more complex to install and maintain than plastic and metal pipes.

4. Drip irrigation pipeline: Drip irrigation is an efficient irrigation method, suitable for water saving and precision irrigation. Drip irrigation pipes are usually made of plastic materials, which can send water droplets directly to the roots of crops, reducing water waste and evaporation.

5. Sprinkler pipes: Sprinklers use sprinklers to atomize water and spray it onto crops. Sprinkler pipes are also usually made of plastic to accommodate different sprinklers and spraying needs.

6. Underground drip irrigation system: This is a system that combines drip irrigation with pipes buried underground, which can reduce water evaporation and pollution and improve water use efficiency.
