PE Water Pipe​ Sizes For Irrigation Application

From a general point of view, it is all about water flow rate for designing an irrigation system poly pipeline by using appropriate poly pipe sizes. As a rule of thumb the faster the water moves through the pipe, the more resistance there is. In simple words, a higher pressure will result in water gauging out quicker.

Sub  Water Pipeline

• Smaller poly piping sizes are usually used as water discharge streamflow.
• It serves as an outlet for connecting the micro dripping or micro sprinkle.
• ​Sub pipeline sizes such as below:
• LDPE 16mm Pipe​
• HDPE 20mm pipe , ( 0.5 Inch Poly Pipe )

​​Mid Water Pipeline

• The mid sizes of poly pipings serve as a divergent point for the water flow.
• Mid sizes poly pipings are usually distributing the water evenly to the desired region.
• Mid pipeline sizes such as below:
• 20mm Poly Pipe , ( 0.5 Inch Poly Pipe )​
• HDPE 25mm pipe , ( 0.75 Inch Poly Pipe )
• HDPE 32mm pipe​ , ( 1 Inch Poly Pipe )

Main Water Pipeline​

• Larger poly piping sizes can accommodate higher water volume streamflow.
• Large poly piping sizes are suitable used near the incoming water sources.
• It can use to collect water from the upper hill as well.

• Main pipeline sizes such as below:

• HDPE 50mm pipe , ( 1.5 Inch Poly Pipe )
• HDPE 63mm pipe , ( 2 Inch Poly Pipe )
• HDPE 90mm pipe , ( 3 Inch Poly Pipe )
• HDPE 110mm pipe​ , ( 4 Inch Poly Pipe )
