Caratteristiche del tubo a parete piena in PE

PE pipe is corrosion-resistant and has a long service life. In China's coastal areas, the underground water level is high and the land humidity is high. When using seamless steel pipe, it must be anticorrosive and tempered with external installation patterns, and its service life is only 30 years.

However, PE pipe can resist the corrosion of various chemical media without anticorrosive treatment. In addition, it will not promote the growth of algae, bacteria or fungi, and its service life will reach 50 years. Good stress cracking resistance: PE pipe has low notch sensitivity, high shear strength, and outstanding environmental stress resistance. Good impact resistance at low temperature: The low temperature brittle temperature of PE pipe is extremely low, and it can be used safely in the temperature range of -60 degrees Celsius.

PE pipes have large circulation capacity and are economical. The inner wall of PE pipe is smooth and does not scale. The absolute roughness ratio of the inner surface equivalent of PE pipe is 1/20 of that of steel pipe, and the circulation capacity of PE pipe with the same diameter, length and pressure is about 30% larger than that of steel pipe, so the economic advantage is obvious. Excellent physical properties.

The performance of medium-density polyethylene is between high-density polyethylene and low-density polyethylene, which not only maintains the rigidity and strength of high-density polyethylene, but also has good flexibility and creep resistance. Moreover, higher-density polyethylene has the characteristics of excellent hot-melt connection, which is beneficial to the installation of plastic pipes. Compared with metal pipes, PE pipes can reduce the project investment by about one third, and the coiled small-diameter pipes can further reduce the project cost.
