In the field of industrial production and chemical transportation, sulfuric acid, as a common strong corrosive medium, places extremely high demands on the corrosion resistance of pipeline materials. PE pipe (polyethylene pipe) is often used in various fluid transportation scenarios due to its excellent chemical stability and cost performance. However, whether PE pipe can withstand sulfuric acid corrosion requires a comprehensive analysis of sulfuric acid concentration, temperature and PE material characteristics.
PE material itself has good chemical inertness, its molecular structure is stable, and it shows strong corrosion resistance to most acid, alkali and salt solutions at room temperature. But the corrosiveness of sulfuric acid is closely related to its concentration: for concentrated sulfuric acid with higher concentration (usually refers to more than 98%), under normal temperature conditions, PE pipe has certain corrosion resistance, because its strong oxidizing property will form a passivation film on the surface of PE, slowing down the corrosion process. However, for dilute sulfuric acid or temperature rise, the corrosion resistance of PE pipe will be significantly reduced, and the penetration of hydrogen ions may cause material aging, cracking, and affect the service life of the pipeline.
In practical applications, when choosing PE pipe to transport sulfuric acid, it is necessary to clarify the concentration, temperature and operating conditions of sulfuric acid. It is recommended to refer to the professional material corrosion resistance data table or consult the manufacturer for technical support. As a professional pipe manufacturer, its PE pipe is produced in strict accordance with national standards. Detailed chemical corrosion resistance parameters will be provided in the product manual to help users choose the type reasonably according to the specific working conditions to ensure the safe and stable operation of the system.
In summary, the corrosion resistance of PE pipe to sulfuric acid is not absolute, and it needs to be scientifically evaluated according to the actual working conditions. In the selection process, key factors such as concentration and temperature are fully considered, and the technical support of regular brands such as AD Pipe can be used to achieve the safety and efficiency of sulfuric acid transportation.
