Why are PE pipes now being used to replace steel pipes?
Perhaps many friends, like you, are also puzzled and wonder: Why can PE pipes replace traditional steel pipes? Let’s dive in and learn about this together!
First, looking solely at the appearance of PE pipes, both the inner and outer walls are exceptionally smooth, and their surface characteristics remain unchanged over time, with low friction resistance. Moreover, PE pipes are energy-efficient: their pressure loss is about 30% lower than that of steel pipes, allowing for the use of smaller pipe diameters. Most importantly, PE pipes boast excellent hygienic performance—they contain no additives and pose no risk of contaminating drinking water. According to ISO standards, polyethylene materials are classified as Grade 0 (the lowest grade), meaning they are mold-resistant. Compared to other commonly used plastic materials, polyethylene exhibits significantly higher resistance to mold growth. Additionally, PE pipes do not easily accumulate scale even after prolonged use. Furthermore, PE pipes offer outstanding overall performance across a wide range of applications: their temperature resistance is exceptional, with a very low embrittlement temperature at low temperatures, enabling them to operate reliably within a temperature range from -40°C to 60°C. Even during winter installation and construction, these pipes will not become brittle or crack. Generally, PE pipes are primarily used for pressurized water conveyance and the distribution of drinking water. Their main application areas include municipal underground water supply systems, building water supply and drainage systems, agricultural irrigation, and landscape water features.
Alright, that’s all for today’s discussion on PE pipes. Now do you understand why they can replace steel pipes?
