9 properties of PE electrofusion flange

We should all know that an item must have good performance if it is widely used. So what are the specific properties of the electrofusion flange? Let me give you a detailed introduction below. Reliable connection. The strength of the joints connected by electrothermal fusion between the electrofusion flange systems is higher than the strength of the pipe body.
Good low-temperature impact resistance. Polyethylene has an extremely low low-temperature embrittlement temperature and can be used safely within the temperature range of ℃. During winter construction, pipe brittleness will not occur due to the good impact resistance of the material.
Good resistance to stress cracking. The electrofusion flange has low notch sensitivity, high shear strength and excellent scratch resistance. The resistance to environmental stress cracking is also very outstanding.
The electrofusion flange has good chemical corrosion resistance and can withstand corrosion from a variety of chemical media. Chemical substances present in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator and therefore will not rot, rust or electrochemically corrode. It also does not promote the growth of algae, bacteria or fungi.
Anti-aging, long service life, polyethylene pipes containing evenly distributed carbon black can be stored outdoors or used for many years without being damaged by ultraviolet radiation.
Good wear resistance. Comparative tests on the wear resistance of electrofusion flanges and steel pipes show that the wear resistance of electrofusion flanges is twice that of steel pipes. In the field of mud transportation, electrofusion flanges have better wear resistance than steel pipes, which means that electrofusion flanges have longer service life and better economy.
Good flexibility. The flexibility of the electrofusion flange 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 installation costs.
The electrofusion flange has small water flow resistance and has a smooth inner surface. Its Manning coefficient is smooth and non-adhesive. It ensures that the flange has a higher conveying capacity than traditional pipes and also reduces the pressure loss of the pipeline. and water transportation energy consumption.
Easy to carry: The fused flange is lighter than concrete pipes, galvanized pipes and steel pipes. It is easy to carry and install. Lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
Electrofusion flanges have a variety of construction technologies. In addition to traditional excavation methods, they can also be constructed using a variety of new trenchless technologies, such as pipe jacking, directional drilling, liner cracking, etc. For some places where excavation is not allowed, it is the only choice, so its application fields are wider.
