摘要:
The present invention deals with the use of pipes made of cross-linked polyethylene for transporting water containing chlorine dioxide. Cross-linked polyethylene has a resistance of more than 3500 hours against water treated with chlorine dioxide when tested according to a modified method of ASTM F2263-03. Especially, the pipes made of cross-linked polyethylene can be used for transporting drinking water which had been disinfected by using chlorine dioxide.
