Galvanized pipe damage, pressure reduction, water leakage repair, Dongguan ductile iron pipe leakage detection hotlineThe purpose of pipeline network environment investigation is to fully understand the on-site situation and prepare for the construction arrangement and method selection of the next step of leakage detection work. It includes pipeline network environment investigation, investigation of ancillary equipment situation, and adjustment of water use situation

Investigation and drainage situation survey, etc.  

(1) Pipeline environment investigation: ① Water supply pressure; ② Pipeline material; ③ Pipeline pavement.  

(2) Auxiliary equipment investigation: Investigate the wells, meters, valves, and plugs in the area, and conduct preliminary investigations into water leakage in all of the above accessories.  

(3) Drainage investigation: Conduct a detailed investigation of underground structures such as drainage pipes and cables near the pipeline network.

The pipeline leak detection plan is as follows:

Understand the degree of water leakage in the fire pipeline, such as reading the hourly leakage volume, pressure value, and its rate of decrease through a water meter. These data are important for analysis. All should use stress free piping

Collect and organize drawings. According to regulations, each fire protection system should have detailed as built drawings, including plan as built drawings, elevation as built drawings, etc. For outdoor fire protection pipelines, as long as there are detailed pipe network drawings, there can be 80%

The probability of detecting water leakage.

There is sound wave vibration near the leakage point. Use a sensor to receive the vibration and find the suspected location of the leakage point. This step requires a lot of detection equipment.

Confirm the suspected leak point by drilling a small hole on the ground and using a mechanical listening rod to directly contact the pipeline to determine if it is a leak point.
