Disinfection processes for drinking water often involve chlorination. The compatibility of piping materials with chlorinated water is essential for long-term system integrity.
Key Property
PVC pipe is not vulnerable to chlorinated water. In contrast, PE pipe can be vulnerable. Disinfectants such as chlorine dioxide, used against pathogens like Legionella and Anthrax, can initiate early brittle fracture in PE pipe due to chemical ageing.
Applications
This resistance makes PVC a suitable material for drinking water distribution systems where chlorination is used for disinfection, ensuring the pipe's long-term performance and preventing material degradation caused by the disinfectant.
FAQ Section
Can chlorinated water damage plastic pipes?
Yes, some plastic pipes like PE can be vulnerable to chemical ageing and brittle fracture when exposed to disinfectants like chlorine dioxide. PVC is not vulnerable.
Is PVC pipe suitable for systems using chlorine disinfection?
Yes, PVC pipe is not vulnerable to chlorinated water and is suitable for such applications.
