The strength of the joint is higher than the strength of the pipe body.

The low temperature embrittlement temperature of polyethylene is very low, and it can be used safely in the temperature range of -40•60℃. During construction in winter, the pipe cracking will not occur because of the good impact resistance of the material.

HDPE irrigation pipe has low notch sensitivity, high shear strength, excellent scratch resistance, and outstanding environmental stress cracking resistance.

HDPE pipes can withstand the corrosion of a variety of chemical media, and the chemicals present in the soil will not cause any degradation of the pipes.

Polyethylene pipes containing 2.2.5% uniformly distributed carbon black can be stored or used outdoors for 50 years without damage from ultraviolet radiation.

The wear resistance of HDPE pipe and steel pipe is 4 times that of steel pipe. 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.

The flexibility of the HDPE pipeline makes it easy to bend, and the engineering can bypass obstacles by changing the direction of the pipeline. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce the installation cost.

HDPE pipes have a smooth inner surface and a Manning coefficient of 0.009.

HDPE pipe is lighter than concrete pipe, galvanized pipe and steel pipe, it is easy to handle and install, lower manpower and equipment requirements, meaning that the installation cost of the project is greatly reduced.
