A good pipeline should not only have good economy, but also have the advantages of stable and reliable interface, impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, PE gas pipes have the following advantages:
1. Reliable connection: The polyethylene pipeline system is connected by electric melting, and the strength of the joint is higher than that of the pipeline body.
2. Good low-temperature impact resistance: Polyethylene has an extremely low low-temperature brittleness 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 brittleness.
3. Good stress cracking resistance: HDPE has low notch sensitivity, high shear strength, excellent scratch resistance, and outstanding environmental stress cracking resistance.
4. Good chemical corrosion resistance: HDPE pipes can withstand corrosion from various chemical media, and the chemicals present in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, therefore it does not undergo decay, rusting, or electrochemical corrosion; In addition, it does not promote the growth of algae, bacteria, or fungi.
5. Anti aging and long service life: Polyethylene pipes containing 2-2.5% uniformly distributed carbon black can be stored outdoors or used for 50 years without being damaged by ultraviolet radiation.
6. Good wear resistance: Comparative tests on the wear resistance of HDPE pipes and steel pipes show that the wear resistance of HDPE pipes is four times that of steel pipes. In the field of mud transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means that HDPE pipes have a longer service life and better economy.
7. Good flexibility: The flexibility of HDPE pipes makes them easy to bend, and in engineering, they can bypass obstacles by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and lower installation costs.
8. Low water flow resistance: HDPE pipes have a smooth inner surface with a Manning's coefficient of 0.009. The smooth performance and non adhesive properties ensure that HDPE pipes have higher transport capacity than traditional pipes, while also reducing pressure loss and water transmission energy consumption in the pipeline.
9. Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes, and steel pipes, making them easier to handle and install. With lower manpower and equipment requirements, it means that the installation cost of the project is greatly reduced.
10. Multiple new construction methods: HDPE pipes have multiple construction techniques. In addition to traditional excavation methods, various new non excavation techniques such as pipe jacking, directional drilling, lining, and cracking can also be used for construction. This is a good choice for places where excavation is not allowed, so PE gas pipelines have a wider range of applications.
There are many advantages to PE gas pipes, and their performance advantages are obvious. There is no need for me to say more. Everyone, hurry up and choose.
