What is Polyethylene Tubing?

PE pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all have a place. Among them, the strong development of PE pipes is the most noticeable.

Good sanitary performance:

A good pipeline should not only have good economy, but also have a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, HDPE pipeline system has the following advantages: Series advantages:

Reliable connection: Polyethylene piping systems are connected by electrothermal fusion, and the strength of the joint is higher than the strength of the pipe body.

Good impact resistance at low temperature: The low temperature brittleness temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60-60 ° C. During construction in winter, due to the good impact resistance of the material, the pipe will not be brittle.

(3) Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength, and excellent scratch resistance. The resistance to environmental stress cracking is also outstanding.

Good chemical resistance: HDPE pipes can withstand the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust, or electrochemically corrode; it also does not promote the growth of algae, bacteria, or fungi.

Aging resistance and long service life: Polyethylene pipes containing 2-2.5% uniformly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.

Good abrasion resistance: A comparative test of the abrasion resistance of HDPE pipes and steel pipes shows that the abrasion resistance of HDPE pipes is 4 times that of steel pipes. In the field of mud transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means that HDPE pipes have a longer service life and better economy.

Good flexibility: The flexibility of HDPE pipes makes it easy to bend. In engineering, the obstacles can be bypassed by changing the direction of the pipes. In many cases, the flexibility of pipes can reduce the amount of pipe fittings and reduce installation costs.

Small flow resistance: HDPE pipeline has smooth inner surface, and its Manning coefficient is 0.009. The smooth performance and non-adhesive properties ensure that HDPE pipelines have a higher transport capacity than traditional pipes, while also reducing the pressure loss and energy consumption of the water pipeline.

Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. It is easy to handle and install. Lower labor and equipment requirements mean that the installation cost of the project is greatly reduced.

A variety of new construction methods: HDPE pipelines have a variety of construction technologies. In addition to traditional excavation methods, a variety of new non-excavation technologies such as pipe jacking, directional drilling, liners, Construction by cracks and other methods is the only option for some places where excavation is not allowed, so HDPE pipelines have a wider application area.
