开发了一个涉及钙、镁、锌、铁、锰、硅、氯化物、正磷酸盐和碳酸盐的络合和溶解度平衡的水化学模型，并将其应用于实验室管道回路试件和石棉水泥管道的现场数据。通过计算相关固体的饱和状态，可以编制图形指南，用于预测锌化合物原位管道涂层的剂量水平，以及由水的天然抑制成分形成的涂层提供的保护。讨论了锌处理、腐蚀性指数和A-C管试件试验的环境影响。包括91个参考文献、表格和图表。

A water chemical model involving the complexion and solubility equilibria of calcium, magnesium, zinc, iron, manganese, silica, chloride, orthophosphate, and carbonate has been developed and applied to laboratory pipe-loop-coupon and field data on asbestos-cement pipe. Calculation of the saturation states of the relevant solids enables preparation of graphic guides for the prediction of dosage levels for in-situ pipe coating by zinc compounds as well as protection afforded by coatings formed by natural inhibitory constituents of the water. Environmental impacts of zinc treatment, aggressiveness index, and A-C pipe coupon tests are discussed. Includes 91 references, tables, figures.
