What is the difference between HDPE pipe and PE pipe?

High Density Polyethylene (HDPE) pipes and Polyethylene (PE) pipes are both made from polyethylene, but they differ in their molecular weight.

HDPE pipes are made using a high-density polyethylene material that has a higher molecular weight than PE pipes. HDPE pipes are stronger and more durable, and they have a higher resistance to impact and abrasion. HDPE pipes are also resistant to chemicals, corrosion, and UV radiation. HDPE pipes are available in a range of sizes and grades, and they can be used for a variety of applications, including water supply, gas distribution, sewer and drainage systems, and industrial applications.

PE pipes, on the other hand, are made using a low-density polyethylene material that has a lower molecular weight than HDPE pipes. PE pipes are less durable and less resistant to impact and abrasion than HDPE pipes. PE pipes are also less resistant to chemicals, corrosion, and UV radiation. PE pipes are available in a range of sizes and grades, and they are commonly used for water supply, irrigation, and gas distribution applications.

In summary, HDPE pipes are stronger, more durable, and have a higher resistance to impact, abrasion, chemicals, corrosion, and UV radiation than PE pipes. HDPE pipes are ideal for more demanding applications, while PE pipes are suitable for lighter duty applications.
