⑴ Reliable connection: The polyethylene pipe system software is connected by electric heating method, and the compressive strength of the joint is higher than the compressive strength of the pipeline itself.
⑵Good low-temperature impact resistance: The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60-60℃. During winter construction measures, because the raw materials have good impact resistance, it is not easy to produce pipe brittleness.
⑶ Good resistance to ground stress cracking: HDPE has low vacancy sensitivity, high shear strength and excellent scratch resistance, and its environmental resistance to ground stress cracking is also very prominent.
⑷Good solvent corrosion resistance: HDPE pipelines can withstand the corrosion of a variety of diversified chemical media, and the chemical substances in the soil are not easy to cause all the degradation effects of the pipeline. Polyethylene is an electrical insulator, so it is not prone to rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi.
⑸Aging resistance: long service life: polyethylene pipes with 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years, and are not easily harmed by ultraviolet radiation.
⑹Good wear resistance: The wear resistance of HDPE water supply pipes and steel pipes is compared with the test instructions, and the wear resistance of HDPE pipes is 4 times that of steel pipes. In the mud transportation industry, HDPE pipes have stronger wear resistance compared with steel pipes, which means that HDPE pipes have a longer service life and stronger rationality.
⑺Good flexibility: The flexibility of HDPE water supply pipe makes it very easy to bend. In engineering, obstructions can be avoided according to the method of 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.
⑻Convenient transportation: HDPE water supply pipes are lighter than concrete pipes, galvanized pipes and steel pipes. It is very easy to transport and install. Lower human resources and machinery and equipment requirements represent a significant reduction in project installation costs.
⑼Various new and upgraded engineering construction methods: HDPE pipelines have a variety of construction techniques. In addition to traditional excavation methods, they can also use a variety of newly upgraded trenchless technologies such as pipe jacking. , Directional drilling, lining pipe, pipe cracking and other methods to carry out engineering construction, which is the only option for some sites where excavation is not allowed, so the main purpose of HDPE pipes is more common.
