How to disinfect PE pipe hydrostatic test?

Release time:

Feb 14,2019

PE pipe trenchless pipe laying technology has a wide range of applications, mainly for the laying, replacement and repair of various underground pipelines. 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 the PE pipe for hydraulic test, how should we carry out disinfection and flushing? Let's take a look at it specifically: 1. After the PE pipe hydraulic test, it should be washed and disinfected before completion and acceptance. 2, flushing should avoid the peak water, with a flow rate of not less than 1.0 m/s flushing water continuous flushing, until the water outlet turbidity, chroma and water inlet flushing water turbidity,

When we use PE pipe for hydrostatic test, how should we disinfect and wash it?
Let's take a look at it specifically:
1. After the hydraulic test of PE pipeline, it shall be washed and disinfected before completion acceptance.
2, flushing should avoid the peak water, with a flow rate of not less than 1.0 m/s flushing water continuous flushing, until the water outlet turbidity, color and water inlet flushing water turbidity, color is the same.
3. Ensure smooth and safe PE pipeline during flushing.
4. The pipeline shall be soaked in clean water with a chloride ion concentration of not less than 20mg/L for 24h and washed again until the water quality management department passes the sampling test.
Only the correct cleaning and disinfection steps can ensure the normal use of the PE pipe, so the staff should have the accuracy of each step in the specific construction to ensure that the maximum effect of the PE pipe can be exerted.
