Construction Protection Measures For PE Pipe Engineering

The common problems with PE pipe cleaning are that the machinery, equipment, and pipelines that cannot be cleaned should be protected by the cleaning system. Before purging the pipeline, it is not allowed to install adjustment valves for orifice plates, loop flanges, critical gate valves, overflow valves, instrument panels, etc. High compressive strength, good ductility, and models with a diameter of 160Mm or less can be packaged in coils, making it convenient for transportation and engineering construction.
There are four blue lines on the surface of PE water supply pipes, and some manufacturers may produce white or other colored pipes, but they all come with blue lines. On the surface of the PE gas pipe, there is an orange or yellow line, so it can be distinguished from the outside.
Analyzing the small amount of water in the raw materials after they enter the processing plant is crucial, not only for the quality inspection of the raw materials, but also for the clarity of the processing technology. Corresponding dryness. If the moisture content is low, the application of transportation spacing.
The leakage detection of PE pipelines mainly focuses on valves, pipeline routes, steel plastic conversion parts, and some auxiliary facilities. However, gas has fluidity, and leaks from the pipeline itself and welding interface locations may occur along loose soil locations. PE pipes have poor UV resistance and are prone to embrittlement, so an external protective layer should be installed.
PE pipes are divided into SDR11 and SDR17.6 series based on wall thickness. The former is suitable for transporting artificial gas, natural gas, and liquefied petroleum gas in the gaseous state, while the latter is mainly used for transporting natural gas. Compared to steel pipes, the construction process is simple and has a certain degree of flexibility.
