HDPE drainage pipe is a replacement product of traditional steel pipe and PVC drainage pipe. It mainly undertakes the tasks of drainage such as rainwater, sewage, farmland irrigation and drainage, etc. It is widely used in roads, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields and slopes caused by high water content, such as slope protection, as well as underground irrigation and drainage systems for agriculture and horticulture.

HDPE is a highly crystalline, non-polar thermoplastic resin. The original HDPE has a milky white appearance and a semi-transparent shape in a thin section. PE has excellent resistance to most living and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. HDPE has excellent electrical properties, especially high dielectric strength, which makes it suitable for wire and cable. Medium to high molecular weight grades have excellent impact resistance, both at ambient temperatures and even at low temperatures of -40F.

HDPE pipe must withstand a certain pressure, and usually choose PE resin with high molecular weight and good mechanical properties, such as HDPE resin. The LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, so it is not suitable as a material for a water supply pressure pipes. However, due to its high health index, LDPE, especially LLDPE resin, has become a common material for the production of drinking water pipes. LDPE and LLDPE resin have low melt viscosity, good fluidity and easy processing, so the range of melt index is also wide, and the MI is usually between 0.3 and 3 g/10 min.


HDPE is a good pipe. It is not only economical, but also have a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance and corrosion resistance. Compared with traditional pipes, HDPE pipe system has the following series of advantages:

(1). Reliable connection: The polyethylene pipe system is connected by electric melting method, and the strength of the joint is higher than the strength of the pipe itself.

(2). Low temperature impact resistance: Polyethylene has a very low temperature embrittlement temperature and can be safely used in the temperature range of -60-60℃. In winter construction, 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, and its environmental stress cracking resistance is also outstanding.

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

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

(6). Good wear resistance: The comparison of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transport, HDPE pipes have better wear resistance than steel pipes, which means HDPE pipes have a longer service life and better economy.

(7). Good flexibility: The flexibility of the HDPE pipe makes it easy to bend. The engineering can bypass the obstacle by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the pipe usage and reduce the installation cost.

(8). Small water flow resistance: The HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than conventional pipes, while also reducing the pressure loss and water consumption of the pipe.

(9). Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install. The lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.

(10). A variety of new construction methods: HDPE pipelines have a variety of construction techniques, in addition to the traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking, directional drilling, liners Construction by means of split pipes, etc. This is the only option for places that are not allowed to be excavated.
