What are the advantages of PE pipe:
1. Corrosion-resistant and long service life. In China's coastal areas, the groundwater level is high and the land moisture is high. The seamless steel pipe must be used for anti-corrosion and installation of outward-direction tempering, and the life span is only 30 years, and the PE pipe can withstand a variety of The erosion of chemical media does not require preservative treatment. In addition, it does not promote the growth of algae, bacteria or fungi, with a service life of 50 years.
2, excellent physical properties. The performance of medium density polyethylene is between high and low density polyethylene, which not only maintains the rigidity and strength of high density polyethylene, but also has good flexibility and creep resistance, and the higher density polyethylene is hotter. The excellent fusion connection performance is beneficial to the installation of plastic pipes.
3. Large circulation capacity and economical cost. The inner wall of the PE pipe is smooth and does not scale. The absolute roughness ratio of the inner surface of the PE pipe is 1/20 of that of the steel pipe. The PE pipe with the same pipe diameter, the same length and the same pressure has a flow capacity of about 30% larger than that of the steel pipe, so the economic advantage is obvious. Compared with metal pipes, PE pipes can reduce engineering investment by about one-third, and small-diameter pipes that can be coiled can further reduce project cost.
4. Good toughness and flexibility. PE pipe is a kind of high-toughness pipe with elongation at break of more than 500%. It has strong adaptability to uneven settlement and dislocation of pipe foundation and good earthquake resistance. Therefore, it is most suitable for earthquake-stricken areas and practice around the world. It is confirmed that the PE pipe is the best shockproof pipe. In addition, the flexibility of the PE pipe is that the PE pipe can be coiled, reducing a large number of connecting pipe fittings. The direction of the PE pipe is easily changed according to the requirements of the construction method. During construction, the obstacle can be bypassed within the bending radius allowed by the pipe to reduce the construction difficulty.
5. Convenient connection, simple construction and various methods. PE pipe body is light, easy to handle, easy to weld, and has few welding ports. When the pipeline is long, the pipe can be used to lay the PE pipe trench. The requirement is much lower than that of the steel pipe trench. When the construction conditions are limited, the electrofusion welding can be used. . In addition, the method of pipe sinking can be used to lay the bottom of the water, which greatly reduces the construction difficulty and engineering cost.
6, good sealing. The PE pipe itself is welded and welded, which essentially guarantees the interface material, the structure and the identity of the pipe body itself, and realizes the integration of the joint and the pipe material. The tensile strength and bursting strength of the interface are higher than that of the pipe body, which can effectively resist the axial stress induced by the internal pressure. Therefore, the sealing performance is very good compared to the rubber ring type or other mechanical joints.
7, easy maintenance, can not stop water, gas maintenance and installation.
8. Good resistance to stress cracking: PE pipe has low notch sensitivity, high resistance to shear strength, and resistance to environmental stress. Low temperature impact resistance: PE tube has a very low temperature embrittlement temperature and can be safely used in the temperature range of -60 degrees Celsius. Good wear resistance. The comparison of the wear resistance of polyethylene pipes and steel pipes shows that its wear resistance is four times that of steel pipes.
