Product introduction
Reference standard: GB15558. 1-2003, GB15558. 2--2005
PE pipe for gas is a replacement product of traditional steel pipe.
PE gas pipe is made of special polyethylene material for gas. Specifications, dimensions and performance meet the requirements of GB15558. 1-2003 and GB15558. 2--2005 standards. The pipe has the characteristics of good flexibility, strong corrosion resistance, light weight and excellent impact resistance.
Features
A good pipeline should not only have good economy, but also have a series of advantages such as stable and reliable interface, impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, HDPE piping system has the following: Series advantages:
1. Reliable connection: the polyethylene pipe system is connected by electric heating, and the strength of the joint is higher than the strength of the pipe body
2. Good low-temperature impact resistance: Poly-Zene has a very low low-temperature embrittlement temperature and can be used safely in the temperature range of (-60-60)℃.
3. Good stress crack resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress crack resistance is also very outstanding.
4. Good chemical resistance: HDPE pipes can withstand the corrosion of a variety of chemical media, and the chemical substances in the soil will not cause any degradation to the pipes. Poly-Zene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi.
5. Anti-aging and long service life: The polyethylene pipe containing 2% 2.5% carbon black evenly distributed can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
The PE gas pipe is made of special polyethylene material for gas. Specifications, dimensions and performance meet the requirements of GB15558. 1-2003 and GB15558. 2--2005 standards. The pipe has the characteristics of good flexibility, strong corrosion resistance, light weight and excellent impact resistance.
Application area
is mainly used for the transmission and distribution of natural gas, liquefied petroleum gas, artificial gas, and can also be used in the fields of chemical, pharmaceutical, papermaking, etc.
6. Good wear resistance: The comparison test of the wear resistance of HDPE pipes and steel pipes shows that the wear resistance of HDPE pipes is 4 times that of steel pipes. In the field of mud transportation, HDPE pipes have better wear resistance than steel pipes, which means that HDPE pipes have a longer service life and better economy.
7. Good flexibility: The flexibility of HDPE pipeline makes it easy to bend. In engineering, obstacles can be bypassed 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.
8. Small water flow resistance: HDPE pipe has a smooth inner surface, and its Manning coefficient is 0.009. Smooth performance and non-adhesive properties Baoxun HDPE pipe has a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water transmission.
9. Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes, which means that the installation cost of the project is greatly reduced.
10. Various new construction methods: HDPE pipelines have a variety of construction techniques. In addition to traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking, directional drilling, and lining can also be used. Pipes, split pipes and other methods are used for construction, which is the only choice for some places where excavation is not allowed. Therefore, HDPE pipelines are more widely used.
