Introduction Of PE Water Supply Pipe Specifications

1. According to the diameter and outer diameter of PE water supply pipes, they can be classified into various models, including 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180mm, 200mm, 225mm, 250mm, 280mm, 315mm, 355mm, 400mm, 450mm, 500mm, 560mm, 630mm, 710mm, 800mm, 900mm, 1000mm, 1200mm, 1600mm, 2000mm, etc.

2. The average outer diameter of PE water supply pipes should correspond to the specific nominal outer diameter. For example, for DN20 PE water supply pipes, the minimum average outer diameter should be 20.0mm and the maximum average outer diameter should be 20.3mm; The minimum average outer diameter of DN25 PE water supply pipe should be 25.0mm, and the maximum average outer diameter should be 25.3mm, etc. For PE water supply pipes with smaller nominal outer diameters, the maximum and minimum average inner diameter differences are mostly controlled within 0.3mm, while for PE water supply pipes with larger nominal outer diameters, the maximum and minimum average outer diameter differences are generally larger.

3. PE water supply pipe coils usually have a nominal outer diameter of DN63mm or less, and their unfolded length is agreed upon by both the supply and demand parties; PE water supply pipes with a nominal outer diameter of DN75mm or more are mostly straight pipes, with lengths generally ranging from 6m, 9m, 12m, etc.

4. The specific pressure levels of PE water supply pipes include 1.6MPA, 1.25MPA, 1.0MPA, 0.8MPA, 0.6MPA, etc. The wall thickness of PE water supply pipes corresponding to different pressure levels also varies. Generally speaking, the larger the pressure they can withstand, the thicker the wall thickness of the corresponding specification. The wall thickness of a DN50 PE water supply pipe is 2.00 millimeters at a pressure rating of 0.6 MPA, while the corresponding wall thickness is 4.60 millimeters at a pressure rating of 1.25 MPA.
