What are the differences in construction difficulties for PE pipes with different pressure grades?

PE pipes of different pressure ratings present varying degrees of difficulty during drag construction.

Generally, PE pipes with higher pressure ratings tend to have thicker walls and greater material strength, which increases the pipe's weight and consequently generates more resistance during dragging, thereby complicating the construction process.

In comparison, the PE pipes with lower pressure ratings have thinner walls and lighter weights, encountering less resistance during dragging and are relatively easier to install.

However, it's important to note that construction difficulty is not solely dependent on pressure grade; it's also influenced by a combination of factors such as pipe diameter, length, geological conditions, and拖拉路线 (dragging route).

In actual construction, all relevant factors must be considered to develop a reasonable construction plan, ensuring the smooth progress of the drag construction.
