We all know that the common methods of PE pipes are electric welding and hot welding. Although these technologies and applications have been used for many years, the leakage of PE pipe joints is often found during normal use. Today we mainly do a brief analysis based on this issue. China's urban pipeline market is the largest application market for water supply pipes, sewage pipes and gas pipes. PE materials Chinese PE materials are widely used in water supply and drainage manufacturing fields because of their high strength, heat resistance, corrosion resistance, non-toxicity and wear resistance. It does not rust, making it an ideal pipe to replace ordinary hot metal pipes.
PE pipe joint connection method is butt joint or socket type. If the annular gap between the joints is filled with solid material, the rigidity and uneven soil sedimentation along the pipeline will cause uneven settlement, the PE pipe joints will be loose and easy to leak. phenomenon.
If the soil quality of PE pipes is uneven, you must use flexible joints, such as various types of rubber ring joints, and improve the construction quality of pipe joints to maintain tightness and prevent leakage.
First of all, it should be ensured that the problem of setting the PE pipe foundation is that the foundation is stable and has sufficient compressive strength. In areas with large terrain changes and soft soil, not only concrete foundations but also piles or wharfs should be installed to prevent PE Tube problem. Leakage occurs when the foundation sinks or breaks.
