Can PE pipe resist sulfuric acid?

PE pipe can be resistant to sulfuric acid. The answer is that PE pipe is generally not resistant to sulfuric acid, and there is a greater risk of using PE pipe to transport sulfuric acid.

PE pipe is widely used in water supply and drainage, rural drinking water transportation and other fields due to its strong corrosion resistance. For example, PE hot melt pipe and PE rural drinking water pipe ensure the safety of daily water by virtue of their stability, but this does not mean that it can resist the erosion of sulfuric acid. Sulfuric acid has strong oxidizing and corrosive properties. After contacting with PE pipe, it will chemically react with polyethylene molecules in the pipe. Chemical bonds such as carbon-carbon bonds and carbon-hydrogen bonds in the molecular structure of polyethylene will gradually break under the strong oxidizing properties of sulfuric acid, resulting in the destruction of the molecular structure of the pipe.

as the chemical reaction continues, the PE pipe will appear obvious corrosion phenomenon. The surface first becomes rough and pits appear, and then the pipe wall gradually becomes thinner, and the strength and toughness decrease sharply. In actual use, once the PE pipe is used to transport sulfuric acid, it may seem normal for a short time, but over time, the pipe will break due to corrosion, causing sulfuric acid leakage, which will not only damage the entire conveying system, but also cause serious safety accidents and environmental pollution problems. For example, when some small factories try to use PE pipes to temporarily transport low-concentration sulfuric acid, it can take weeks or months, and there will be pipeline leakage, and eventually the pipeline has to be replaced, which not only increases the cost, but also affects the production schedule.

Although PE pipes have certain tolerance in some weak acid and weak alkali environments, the corrosiveness of sulfuric acid far exceeds its tolerance range. For the occasion where sulfuric acid needs to be transported, special acid-resistant pipes should be selected, such as polypropylene (PP) acid-resistant pipes, rubber-lined pipes, glass-lined pipes, etc. These acid-resistant special pipes are specially designed and manufactured, with stronger chemical stability and corrosion resistance, and can be used stably in sulfuric acid environments for a long time.
