PE pipe advantages introduction

1、First of all, PE pipe corrosion resistance, long service life, in China's coastal areas, high water table, land humidity, the use of seamless steel pipe must be anti-corrosion and do the installation of the Yang grain outward hammering, and the life of only 30 years, while PE pipe can resist the erosion of a variety of chemical media, without anti-corrosion treatment. In addition, it will not promote the growth of algae, bacteria or fungi, and the service life of 50 years.

2、Excellent physical properties. Medium density polyethylene performance between high and low density polyethylene between the two, both maintain the rigidity and strength of high density polyethylene, but also has good flexibility, creep resistance, and more than high density polyethylene has the characteristics of excellent performance of hot melt connection, which is conducive to the installation of plastic pipe.

3、Circulation capacity, economically cost-effective. PE pipe smooth inner wall, no scaling. PE pipe inner surface equivalent absolute roughness ratio is 1/20 of steel pipe, the same pipe diameter, the same length, the same pressure PE pipe circulation capacity is about 30% larger than that of steel pipe, so the economic advantage is obvious. Compared with metal pipes, PE pipes can reduce the project investment by about one-third, and the small diameter pipes that can be coiled can further reduce the project cost.

4、PE pipe is a kind of high toughness pipe, its elongation at break is more than 500%, its adaptability to uneven settlement and dislocation of pipe foundation is very strong, and its seismic resistance is good, therefore, it is most suitable for areas with seismic hazard, and practice around the world confirms that PE pipe is the best pipe with seismic resistance. In addition, the flexibility of PE pipe is that PE pipe can be coiled, reducing a large number of connecting fittings. the direction of PE pipe is easily changed according to the requirements of construction methods. During construction, it can bypass obstacles within the bending radius promised by the pipe and reduce the construction difficulty.
