HDPE (High Density Polyethylene) and LDPE (Low Density Polyethylene) are two different types of plastic pipe. While both can be used for irrigation, there are some differences between the two.
HDPE is typically stronger and more durable than LDPE, which makes it a better choice for larger irrigation systems. LDPE, on the other hand, is more flexible and easier to work with, making it a better choice for smaller systems.
