PE pipes have already penetrated into our daily lives, including industry and other fields. We need to know the specific steps of water pressure testing and disinfection knowledge for PE pipes, which is also beneficial for their normal use.
Firstly, after the water pressure test of the PE pipeline, it should be flushed and disinfected before completion acceptance.
Secondly, when flushing the PE pipe, it should avoid peak water usage and continuously flush with flushing water with a flow rate of not less than 1.0m/s until the turbidity and chromaticity at the outlet are the same as those at the inlet.
Thirdly, during flushing, ensure that the PE pipeline is unobstructed and safe.
Fourthly, the pipeline should be soaked in clean water with a chloride ion concentration of not less than 20mg/L for 24 hours, then rinsed again until the water quality management department takes a sample and tests it to be qualified.
In conclusion, only by correctly mastering the cleaning and disinfection steps of PE pipes can the normal use of PE pipes be ensured. At the same time, safety must be taken into account during the water pressure testing experiment.
