High Density HDPE PN20 Large Diameter Polyethylene Pipe For Water Supply
HDPE pipe is a highly crystalline, non-polar thermoplastic resin. Generally, the application range of PE pipes for water supply pipelines is below 40°C, and cannot be used for hot water delivery pipelines. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE pipe material has excellent resistance to most household and industrial chemicals. Certain types of chemicals are chemically aggressive, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride).

1. Good chemical corrosion resistance: HDPE pipelines can withstand the corrosion of a variety of chemical media, and the chemical substances in the soil will not cause any degradation to the pipeline. Polyethylene 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.
2. Anti-aging and long service life: The polyethylene pipe containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
3. 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.
4. 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.
5. Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. It is easy to handle and install. Lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
Connection of pipes:
1. Electrothermal fusion: A special electric fusion welding machine is used to connect the straight pipe to the straight pipe, and the straight pipe to the pipe fittings. Generally used for pipes below 160mm.
2. Hot-melt butt connection: use a special butt welding machine to connect the pipes, which are generally used for pipes above 160mm.
3. Steel-plastic connection: It can be connected by flange, screw thread and other methods.
In order to facilitate construction and ensure construction quality, corresponding tools should also be prepared.
Such as: rotary cutter - cutting pipes; rotary scraper - scraping off the oxide skin on the surface of the pipe; wall scraper - scraping off the scale on the surface of large-diameter pipes; gas cutting tool - realizing gas cutting on-site operation.
