Can PE pipe be airtight tested?

In the construction of water supply and drainage, gas transportation and other projects in Wuhan, Hubei, PE pipes, especially PE water supply pipes, have become the first choice for many projects due to their advantages such as corrosion resistance and flexibility. After the installation of PE pipes, the inspection of engineering quality is crucial, and the airtight test is the key link to detect the sealing of PE pipes. So, can PE pipes be airtight tested? The answer is yes, through scientific and standardized airtight tests, the sealing and safety of PE pipes can be effectively guaranteed during operation.

The airtight test of PE pipes is mainly achieved by filling the pipeline with a certain pressure of gas. Before the test, the two ends of the PE pipe need to be sealed to ensure that the gas will not leak from the pipeline port. Subsequently, professional inflatable equipment is used to slowly fill the pipeline with air or inert gas (such as nitrogen) and raise the pressure to a specified value. This specified pressure is not set arbitrarily, but is determined according to the design pressure of the PE pipe, the diameter of the pipe and the relevant industry standards. For example, the PE pipe used in the gas transmission project usually has a higher airtight test pressure than the PE pipe in the water supply and drainage project.

When the pressure in the pipeline reaches the specified value, it enters the critical observation stage. At this time, the construction staff will use pressure monitoring instruments to record the pressure change in the pipeline in real time. If within the specified time, the pressure remains stable and does not drop significantly, which indicates that the air tightness of the PE pipe is good, and the pipeline does not have leakage points at the connection and the pipe wall itself, which can meet the normal use needs; on the contrary, if the pressure is significantly reduced, it means that there are leakage points in the pipeline, and the entire pipeline system needs to be carefully checked in time. During the investigation process, soapy water can be used to detect the pipeline joints, interfaces and other parts. Once bubbles are found, the leakage point can be accurately located, and then the leakage point is repaired. After the repair is completed, the air tightness test needs to be carried out again until the pressure is stable to ensure that the sealing of the PE pipe meets the requirements.
