Whether it is urban drinking water pipeline or rural safe drinking water pipeline, PE water pipe plays a very important role in this. Then why choose PE water pipe as the transport pipe of tap water? What's so good about PE water supply pipe? Here's a breakdown for you. First of all, we should look at the raw materials. The important raw material of PE tube is polyethylene with high density (that is, HDPE, generally referred to as PE). Polyethylene is the molecular structure of ethylene (C2H4). Ethylene is one of the world's largest production of chemical products, ethylene industry is the key to the petrochemical industry, ethylene products account for more than 75% of petrochemical products. Therefore, the raw materials of PE tube are rich and colorful, relatively low price, and usually there will be no shortage. With the development of technology, the polyzene material used by PE for water pipes has been changed from PE63, PE80 to PE100, which is widely used today. PE100 grade raw material means that the pipe produced by it can be maintained for 50 years after normal start-up at room temperature 20°C. The minimum compressive strength (MRS) is 10MPa. The MRS Value of PE80 is 8MPa. Later, with the improvement of polyzene production technology, PE112 grade materials will be widely used. Different grades of PE raw materials are manufactured with the same diameter and nominal diameter of the pipe thickness regulations are not the same. The higher grade of materials, the thinner they can be under the same pressure, the lower the required materials, the smaller the cost, and the higher the cost performance.
Another is to look at its performance indicators, reliable PE to water pipe manufacturers production pipeline in the laying of backfill soil, the normal life of more than 50 years, almost rarely must run maintenance. PE pipeline quality is relatively light, convenient transportation engineering construction, pipeline welding method is simple, spare parts need less. Under normal circumstances, the hot melt socket or connection is selected. The actual operation is not convenient in the narrow space or there are special requirements can also use electric fusion connection. The demand for pipe trench basic, foundation buried depth and backfill soil materials is relatively low, convenient construction, faster construction speed, low comprehensive cost of engineering projects. It is precisely because of these advantages of PE water pipes, so its wide range of use, including urban drinking water power supply, rural safe drinking water, landscaping engineering water supply, agricultural water-saving irrigation water supply, direct buried fire water pipe network, siphon drainage, landfill permeability, food chemical industry, communication network these industries. Its characteristics also determine that it has a variety of laying and installation methods, in addition to the common excavation trench layout, but also by traction equipment in the form of dragging trenchless pipe laying. This makes it possible to assemble pipes in the old city reconstruction planning under the premise that the original equipment on the ground can not be destroyed, and it is also very suitable for upgrading and maintenance in the form of replacing the old pipe with a new PE pipe. |
