Which type of pipe is permeated by fuel oil?

Polyethylene pipe is identified as being permeable to fuel oil due to its chemical structure. Polyethylene is a type of plastic made from polymerized ethylene, and while it exhibits excellent resistance to many chemicals, it is not as strong against hydrocarbons like fuel oil. The long-chain molecules in polyethylene can facilitate the absorption of fuel oils, leading to potential degradation of the pipe over time when exposed.

On the other hand, materials like PVC (Polyvinyl Chloride) and steel pipes have different resistance properties. PVC pipes are generally resistant to a wide range of chemicals and are not permeated by fuel oils. Steel pipes, while they can corrode in the presence of certain substances, do not allow the permeation of fuel oil in the same manner as polyethylene. Polypropylene pipe also shares some chemical resistance properties, making it suitable for various applications but not as susceptible to permeation by fuel oils as polyethylene. This understanding of material properties is essential for selecting the appropriate pipe type for different applications in water treatment and related fields.
