How to disinfect the PE pipe water pressure test?
PE pipe non-excavation pipe laying technology has a wide application field, and is mainly used for laying, replacing and repairing various underground pipes. With the continuous maturity of trenchless technology and the continuous improvement of construction technology and equipment, its application fields are also expanding. When we use PE pipes for hydrostatic testing, how do we do the disinfection? Let's take a look at it in detail:
1. After the PE pipeline hydraulic pressure test, it should be washed and disinfected before completion acceptance.
2. When flushing, avoid the peak of water consumption, and rinse continuously with the flushing water with a flow rate of not less than 1.0m/s until the turbidity and chroma at the water outlet are the same as the turbidity and chroma of the flushing water at the water inlet.
3. When flushing, ensure that the PE pipeline is unblocked and safe.
4. The pipeline should be immersed in clean water with a concentration of not less than 20mg/L chloride ion for 24h, and rinsed again until the water quality management department has passed the sampling test.
Only the correct cleaning and disinfection steps can ensure the normal use of the PE pipe, so the staff should ensure the accuracy of each step in the specific construction to ensure the maximum efficiency of the PE pipe.
