Hubei anti-aging PE gas pipe | Municipal buried gas pipeline, long-term stable gas supply

Anti-aging PE gas pipe adapts to the needs of buried scenes in Hubei

The temperature difference between winter and summer in Hubei is large, the soil pH in some areas is high, and the underground humidity fluctuates greatly, which requires higher weathering and corrosion resistance of buried gas pipelines. Anti-aging PE gas pipes are added with special weathering masterbatch, which has excellent stress cracking resistance and acid and alkali corrosion resistance. The service life can reach 50 years under normal buried environment, which is fully suitable for the long-term service needs of municipal gas pipelines.

Core Criteria for Selection of Municipal Buried Gas Pipelines

The selection of municipal buried gas pipelines needs to be comprehensively judged according to the parameters such as soil corrosion, buried depth pressure, and gas supply load in the area where the project is located, and the pipes with ring stiffness in line with national standards and excellent interface sealing performance are preferred. The selection in Hubei area can focus on PE gas pipes with higher weathering grades, which can better resist the dual test of high temperature in summer and low temperature frost heave in winter, and reduce the risk of later operation failure.

Key points of construction specifications for buried PE gas pipes

Before construction, it is necessary to thoroughly clean up the gravel and sharp debris in the pipe trench to avoid scratching the outer wall of the pipe and affecting the service life; the heating temperature and cooling time should be strictly controlled during hot melt connection to ensure that the interface tightness is up to standard; when backfilling, it is necessary to cover the top of the pipe with fine sand for more than 30 cm, and then backfill the original soil layer by layer. It is strictly forbidden for heavy machinery to directly roll the uncovered pipe. After the construction is completed, the air tightness and stress testing should be completed according to the specifications, and it can be put into use after confirming that there is no hidden danger of leakage.

Performance advantages of PE gas pipe for long-term gas supply

Compared with traditional metal pipes, anti-aging PE gas pipes are lighter in weight, lower in transportation and construction costs, and do not require additional anti-corrosion treatment, resulting in a significant reduction in later operation and maintenance costs. Excellent anti-aging properties can support pipes to withstand long-term erosion in complex underground environments without corrosion, cracking and other problems, effectively reducing the probability of gas leakage, and ensuring the long-term stable operation of municipal gas supply networks.
