Material changes brought about by centralized gas supply
Centralized supply of gas can not only reduce losses but also bring collective economic benefits to gas companies, but also save time and effort for ordinary people, making it safer and more convenient to receive more and better services.
To achieve comprehensive adoption of collective supply of gas or natural gas, it is necessary to improve reliable pipelines and high-quality services. Of course, people are accustomed to using gas tanks and find it difficult to quickly accept them, which is also caused by numerous concerns. Can collective gas supply ensure safety and accuracy of measurement? This requires the promotion and development of practical and feasible strategies by relevant departments, as well as the provision of safe and reliable materials.
PE pipes for water supply were recognized and tested in practice by the general public earlier than the popularization of gas pipes. Therefore, this can be used as a starting point, and pipes that are just suitable for water supply can also show their skills in gas, which is determined by their essential characteristics:
Reliable connection: Polyethylene PE gas pipeline systems are connected by electric heating fusion, and the strength of the joints is higher than the strength of the pipeline body. 2. Good low-temperature impact resistance: Polyethylene has an extremely low low-temperature embrittlement temperature and can be safely used within the temperature range of -60-60 ℃. During winter construction, due to the good impact resistance of the materials, there will be no occurrence of pipe brittle cracking. Third, good resistance to stress cracking: it has high shear strength, excellent scratch resistance and outstanding resistance to environmental stress cracking. 4. Good chemical corrosion resistance: The chemical substances present in the soil will not cause any degradation effect on PE gas pipelines. Polyethylene is an insulator for electricity, so it will not undergo decay, rust, or electrochemical corrosion; Moreover, it does not promote the growth of algae, bacteria, or fungi. 5. Aging resistance and long service life: Polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored outdoors or used for 50 years without being damaged by ultraviolet radiation. Six good wear resistance: wear resistance is four times that of steel pipes. PE pipes have a longer service life and better economy. Good flexibility: It is easy to bend, and in engineering, it can bypass obstacles by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce installation costs. Convenient handling: PE pipes are lighter than concrete pipes, galvanized pipes, and steel pipes, making them easier to handle and install. The lower labor and equipment requirements mean a significant reduction in the installation cost of the project. Nine kinds of new construction methods: There are a variety of construction technologies. In addition to the traditional excavation methods, a variety of new non excavation technologies can also be used for construction, such as pipe jacking, directional drilling, lining, pipe splitting, etc. This is the only choice for places where excavation is not allowed, and PE pipes are more widely used.
