Specifications of PE water supply pipes

PE water supply pipe, that is, polyethylene water supply pipe, has the advantages of stable chemical properties, wide adaptability to temperature, and long service life. It is a very popular pipe material at present, and there are many specifications of PE water supply pipe. This will be introduced in detail.

1. According to the diameter of the PE water supply pipe, that is, the outer diameter, the model can be divided into: 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm, 125mm, 160 mm, 180 mm, 200 mm, 225 mm, 250 mm, 280 mm, 315 mm, 355 mm, 400 mm, 450 mm, 500 mm, 560 mm, 630 mm, 710 mm, 800 mm, 900 mm, 1000 mm , 1200mm, etc., all in millimeters.

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

3. The nominal outer diameter of the PE water supply pipe coil is usually below DN63mm, and its expansion length is negotiated by both parties; while the PE water supply pipe with a nominal outer diameter above DN75mm is mostly a straight pipe, and its length is generally 6m, 9m, 12m, etc.

4. The specific pressure levels of PE water supply pipes are: 1.6MPA, 1.25MPA, 1.0MPA, 0.8MPA, 0.6MPA, etc. The specifications and wall thicknesses corresponding to PE water supply pipes with different pressure levels are also different. Generally speaking, the pressure they bear The larger the corresponding specification, the thicker the wall thickness. For example, the wall thickness of PE water supply pipe of DN50 is 2.00 mm under the pressure level of 0.6MPA, and the corresponding wall thickness is 4.60 mm under the pressure level of 1.25MPA.

The above is the introduction of relevant information about the specifications of PE water supply pipe, I hope the above content can provide you with certain help.
