1. What is the pressure of PE pipe?

According to the national standard requirements of GB/T13663-2000, the pressure of PE pipes can be divided into six levels: 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, and 1.6MPa. So what does this data mean? Very simple: For example, 1.0 MPa, which means that the normal working pressure of this type of Hdpe Fittings is 1.0 MPa, which is what we often call 10 kg pressure. Of course, in the previous pressure test, according to the requirements of national standards, it needs to be pressure 1.5 times. Keep the pressure for 24 hours, that is, the test is carried out with a water pressure of 15 kg.

2. What is the SDR value of PE pipe?

The SDR value, also known as the standard size ratio, is a ratio of the outer diameter to the wall thickness. We usually use the SDR value to represent the kilogram pressure rating. The corresponding SDR values ​​of the six levels of 0.4MPa, 0.6MPa, 0.8MPa, 1.0MPa, 1.25MPa, and 1.6MPa are: SDR33/SDR26/SDR21/SDR17/SDR13.6/SDR11.

Third, the question of the diameter of the PE pipe

Generally, PE pipes have a diameter of 20mm-1200mm. The diameter we are talking about here actually refers to the outer diameter. For example, a PE pipe of De200 1.0MPa is actually a PE with an outer diameter of 200, a pressure of 10 kg, and a wall thickness of 11.9 mm. pipeline.

Fourth, the calculation method of the meter weight of the PE pipe

When many users come to inquire about the price of Hdpe Pipe Fittings, some will ask how much is a kilogram, we need to use one piece of data here-meter weight.

We will write some formulas for calculating the meter weight of PE pipes. Friends in need will remember them. It will be helpful for future work:

Meter weight (kg/m)=(outer diameter-wall thickness)*wall thickness*3.14*1.05/1000

Well, that’s all for today’s content. For more knowledge about PE pipes, please continue to pay attention to us. Join hands with Shentong to win the market, welcome to inquire.
