What is the cause of the burst of PE water supply pipe production line?What is the cause of the burst of PE water supply pipe production line?
For various reasons, sometimes cracks appear in the pipes of the water supply network. If it is not repaired in time, it will cause great damage. It not only constitutes a loss to the water supply company, but also transports users to the inability to use water, and even brings some potential safety hazards.
Analyze the cause of pipe burst in the PE water supply pipe production line:
1. Temperature stress coefficient: In the rigid joint pipeline, temperature stress occurs when the temperature changes, causing the pipeline to burst. Especially under different soil water content, the frost heave coefficient is different, and the tube bursts frequently in the spring and autumn freezing and freezing seasons. In addition, if the pipeline is too shallow to be laid below the freezing line, it will crack due to temperature stress.
2. Pipeline interface elements: Pipeline interface is one of the important links in the pipeline construction process. Interface method and filler selection is one of the important contents of pipeline engineering design. At present, there are defects of too hard and too hard fillers for pipe joints. The pipe is subjected to lateral thrust, the socket is pulled, the socket is pressed, and the tensile strength of the cast iron pipe is poor, causing the socket to crack.
3. Pipeline construction quality: the pipeline is buried too deep or too shallow and simply bursts. When the pipeline is buried too deep, because the upper load increases the pipeline without foundation, the pipeline will collapse and burst. When the buried depth of the pipeline is too shallow, the resistance to high pressure is poor. Under the effects of the soil layer above the pipeline, the static road load and the dynamic load of traffic vehicles, the pipeline simply cracked.
