Application of water chemical stability evaluation methods in ductile iron pipe system
Ductile iron pipes are widely used to transfer water,the determination of ductile iron pipe internal protection should be done based on scientific and systematic evaluation of water quality.In June 2022,ISO/TR4340 2022:《water aggressiveness evaluation and optimized lining choice》was published.Combined with the drafting process of ISO/TR4340 2022,this paper will discuss the evaluation of water chemical stability and the guidance for internal protection of ductile iron pipes.
