PE water supply pipe has the advantages of stable and reliable interface, impact resistance of raw materials, anti-cracking, anti-aging, anti-corrosion, etc. Compared with traditional pipes, PE water supply pipes are easier to construct. Below, we will control PE during construction What are the technical standards for water supply pipes?
The PE water supply pipe is connected by electric heating method, and the compressive strength of the joint is higher than the compressive strength of the pipe itself. The low temperature embrittlement temperature of polyethylene is low, and it can be safely used in the temperature range of -60-60°C. During construction in winter, because the raw materials have good impact resistance, the pipe is not prone to brittleness. PE has low vacancy sensitivity, high shear strength and anti-scratch work ability, and its resistance to environmental stress cracking is also very prominent.
PE water supply pipes can withstand the corrosion of a variety of diversified chemical media, and the chemical substances in the soil layer are not easy to produce all the dissolving effects on the pipes. 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. Its polyethylene pipe with 2-2.5% joint distribution of carbon black can be placed or used outdoors for 50 years, and it is not easy to be harmed by ultraviolet radiation. The wear resistance of PE pipes is 4 times that of steel pipes. In the mud transportation industry, compared with steel pipes, PE pipes have stronger wear resistance, which means that PE pipes have a longer service life and stronger rationality. The toughness of PE pipe makes it very easy to bend. In engineering, obstacles can be avoided according to the method of changing the direction of the pipe. In many places, the toughness of the pipe can reduce the amount of pipe fittings used and reduce the installation cost.
The PE water supply pipe has a smooth inner surface. The smooth performance and non-adhesive characteristics ensure that the PE pipe has a higher transportation capacity than the traditional pipe, and at the same time, it also reduces the pressure damage of the pipeline and the energy consumption of water transportation. PE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. It is very easy to transport and install. The lower human resources and facility requirements represent a significant reduction in project installation costs. PE pipelines have a variety of construction technologies. In addition to traditional excavation methods for engineering construction, they can also use a variety of new non-excavation technologies such as pipe jacking, fixed drilling, liner, pipe cracking, etc. Engineering construction is the only option for certain sites where excavation is not allowed. Therefore, PE pipes have been recognized by everyone, and their main uses are very common.
