August 22, 2024 – In recent years, PE pipes have gained immense popularity in the market due to their wide range of applications and excellent performance. However, as market demand has surged, some non-compliant piping materials have also emerged, posing challenges for consumers during selection. Identifying the quality of PE pipes is crucial, especially when it comes to water supply pipes that directly impact people’s healthy living.
Initially, from an aesthetic perspective, high-quality PE pipes should exhibit a smooth and flawless inner and outer surface, devoid of defects like bubbles, dents, or impurities. Conversely, inferior PE pipes might present an uneven surface, with pits or conspicuous indentations. Moreover, one can initially gauge the quality of PE pipes through olfaction. Premium PE pipes emit a slight plastic aroma during processing or when heated to melting, which dissipates upon cooling; whereas, substandard pipes might release a pungent odor.
Beyond visual inspection and smell, assessing the elongation at break of PE pipes offers another method to determine their quality. A higher elongation at break indicates superior flexibility and performance. Notably, top-notch PE pipes can withstand stretching up to 3.5 times their original length without rupturing. Nevertheless, the most reliable approach remains the pressure test. Brand-new PE pipes can endure 1.5 times the standard pressure, whereas pipes made from recycled materials can only handle their inherent pressure.
HDPE pipes, crafted from ethylene copolymerized thermoplastic polyolefins, boast numerous advantages such as corrosion resistance, smooth inner walls, high strength, and remarkable flexibility. When compared to traditional piping materials, HDPE pipes excel in weight, corrosion resistance, water flow resistance, ease of installation, and cost-effectiveness. Significantly, their extended lifespan and superior hygienic properties effectively tackle the issue of secondary drinking water pollution.
Furthermore, PE piping materials are characterized by their wear resistance, strong resistance to stress cracking, and ease of maintenance. These attributes have facilitated the widespread application and promotion of PE pipes in various sectors. Especially in gas and water supply fields, the installation expenses of PE pipes are typically 50% lower than those of steel pipes. Additionally, their lightness, ease of handling and connecting, swift installation, and secure, leak-proof connections have garnered immense favor among users.
According to the Color Masterbatch Industry Network, advancements in petrochemical industries and continuous improvements in HDPE pipe manufacturing techniques have led to a more diverse range of HDPE piping products. Considerable progress has also been made in new product technology research and development, installation design theories, and construction techniques. These advancements provide robust support for the broader application of PE pipes.
