Precautions for selecting PE water supply pipes: What is the range of applications for PE pipes? What we will be discussing regarding PE pipes today is related to this topic. It is hoped that through the information presented in this article, readers will be able to gain some understanding of the application areas of PE pipes. Now, let’s take a look at an overview of these topics together with the experts from Zhenjiang Qida Anti-corrosion Materials Co., Ltd. Considerations for choosing PE drainage pipes and PE water supply pipes; Application areas of PE pipes. 1. Check the raw materials used by the manufacturers of PE drainage pipes to see if they are graded composite materials. It is recommended to use PE100-grade raw materials for manufacturing PE pipes ； 2. Is the quality control implemented by PE pipe manufacturers strict? Are there complete testing equipment and relevant management procedures in place for the selection of PE water supply pipes to ensure proper management and control? ； Do the PE drainage pipe specifications meet those listed in the PE drainage pipe specification table? ； 3. Assess defects in the PE drainage pipe based on its appearance, gloss, color uniformity, as well as the presence of dents, pores, water marks, impurities, and so on ； 4. Whether the outer diameter, wall thickness, ellipticity, etc. of the PE pipe meet the relevant requirements and application specifications ； Do the PE drainage pipe standards meet the requirements? ； You may want to know what aspects should be considered when evaluating PE drainage pipes, as well as a summary of their characteristics. Although China produces large amounts of PE and PP resins, there are not many resins suitable for use in manufacturing pipes. In particular, there is even less resin specifically designed for PE pipes used in urban water supply and gas transmission, as well as PP-R resins used for building hot and cold water systems; therefore, a certain amount of resin specialized for plastic pipes still needs to be imported. In practical applications, PE water supply pipes include medium-density polyethylene pipes and high-density polyethylene pipes. They are divided into SDR11 and SDR17.6 series based on wall thickness. The former is suitable for transporting gaseous artificial gas, natural gas, and liquefied petroleum gas, while the latter is mainly used for transporting natural gas. During the installation of PE pipes, the following steps need to be followed: 1. Trench excavation and foundation preparation 2. Pipe laying and backfilling 3. Hydrostatic testing, flushing, and disinfection 4. Completion and acceptance of the piping system. After the pipes are installed, it is also important to pay attention to their maintenance. For pipe damage caused by external factors such as foundation settlement of the pipes, temperature changes, and variations in external loads, corresponding measures should be taken after the pipes are repaired to eliminate these various external influences. If the article titled “Points to Consider When Choosing PE Water Pipes – Applications of PE Pipes” prepared by the PE pipe manufacturers is helpful to you, we hope you will save it. If there are any shortcomings, we would appreciate it if you could point them out so that we can make further improvements.
