【摘要】 球墨铸铁管作为广泛应用的输水管材，其内部腐蚀防护方案的确定需要对输送水质进行科学和系统的评估。2022年6月，ISO/TR4340 2022:《water aggressiveness evaluation and optimized lining choice》发布，本文结合该技术报告的编制过程，探讨水质化学稳定性评估对球墨铸铁管内部腐蚀防护方案的指导意义。更多还原

【Abstract】 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/TR43402022, this paper will discuss the evaluation of water chemical stability and the guidance for internal protection of ductile iron pipes.更多还原
