Core Advantages of PE100 Buried Gas Pipe Adapting to Municipal Gas Engineering

The buried gas pipe produced by PE100 grade raw materials is a commonly used pipe in current municipal gas projects. Compared with traditional metal pipes, it has excellent acid and alkali corrosion resistance, no additional anti-corrosion treatment is required after buried laying, and the normal service life can reach more than 50 years; good flexibility can be adapted to geological settlement scenes in some areas of Hubei, and there will be no cracking and leakage due to soil displacement; it has excellent air tightness, and the leakage rate during gas transmission is lower than that of traditional pipes, which fully meets the safety standards of municipal gas transportation.

Precautions for the selection of PE gas pipes in Hubei

In view of the climatic characteristics of high temperature and humidity in summer and low temperature freezing damage in winter in Hubei, when selecting the type, it is first necessary to confirm that the pipe meets the national standard GB15558.1, and it is clearly produced as PE100 grade raw materials, and the weather resistance index meets the local use requirements; secondly, according to the design pressure of the municipal pipe network, choose the corresponding wall thickness and pressure grade pipes, and prohibit the use of low-grade PE80 pipes instead. At the same time, it is necessary to match the burial depth requirements of different road sections to avoid potential safety hazards in later use.

PE100 Buried Gas Pipe Construction Core Specification

Before construction, it is necessary to clean up the gravel and sharp debris in the pipe trench to avoid scratching the outer wall of the pipe; hot-melt or electrofusion technology is preferred for connection to ensure that the strength of the interface is higher than that of the pipe body to avoid leakage of the interface; after the laying is completed, the air tightness test should be done according to the specifications, and then backfill after passing. When backfilling, cover the top of the pipe with fine sand to more than 30cm, and then use the original soil to layer and tamp, prohibiting heavy machinery from directly rolling the unfilled pipe.

Municipal gas engineering is related to public safety. The selection of compliant PE100 buried gas pipes and the construction in strict accordance with specifications can effectively reduce the later operation and maintenance costs and ensure the long-term stability and safety of gas transportation.
