The thickness of PVC agricultural hoses can vary according to specific uses and needs, and different application scenarios may require different thicknesses of PVC hoses. Generally speaking, the thickness of PVC agricultural water belt is usually between 0.5 millimeters (mm) and 2 millimeters (mm). The following are some common PVC agricultural water belt thickness ranges and their applicable situations:

1. 0.5 millimeter (mm) to 1 millimeter (mm): This thinner PVC hose is suitable for some light irrigation and agricultural purposes, such as flower beds, small orchards or vegetable planting. They are usually used when water pressure is low.

2. 1 millimeter (mm) to 1.5 millimeter (mm): This is a medium-thickness PVC hose, suitable for general agricultural irrigation, such as large orchards, fields, farmland, etc. They can handle moderate water pressure situations.

3. 1.5 millimeters (mm) to 2 millimeters (mm): This thicker PVC hose is suitable for a wider range of agricultural irrigation, such as large farms or situations that require higher water pressure. They are generally more durable and able to withstand higher pressures.

It should be noted that the following factors should also be considered when choosing the thickness of the PVC hose:

-Irrigation system design requirements: According to your irrigation system design and water flow requirements, choose the appropriate thickness of the hose.

- Water pressure of the water source: If your water source provides high water pressure, you may need to choose a thicker hose for durability and performance.

- Environment of Use: If the hose will be exposed to sunlight, weather and other environmental factors, you may need a more durable thickness.

- Budget: Thicker hoses are generally more durable, but can also be more expensive. You need to make a trade-off between performance and budget.
