PE water supply pipe models are mainly categorized by pipe diameter and pressure rating.

In terms of pipe diameter, common sizes include small diameters such as 20mm, 25mm, 32mm, 40mm, and 50mm, as well as larger diameters like 63mm, 75mm, 90mm, and 110mm. Even larger options are available, such as 160mm and 200mm.

Pressure ratings typically include 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, 1.6MPa, and so on.

A variety of combinations of pipe diameters and pressure ratings meet the needs of various water supply projects. For instance, small diameters and low pressures are suitable for residential water supply, while large diameters and high pressures are commonly used for urban main water supply pipelines. Selection should be based on a comprehensive consideration of actual project flow and pressure requirements, among other factors.
