Standards for internal anti-corrosion coatings in drinking water pipelines and related construction methods
Thread Content
Dear seniors! I am currently working on a water supply network project and need information regarding the technical requirements and **standards for internal anti-corrosion coatings in drinking water pipelines. I’ve searched for a long time but haven’t found any relevant technical specifications or specific construction methods. The few options I know that could be used as internal coatings for drinking water are as follows: IPN8710 non-toxic coating, GH102 type (white, non-toxic) epoxy-ceramic coating, 901 porcelain glaze coating, and cement mortar lining. But what I really want to know is where these relevant standards and requirements can be found? Are there any relevant construction methods or techniques? I hope you will kindly offer your guidance!
The national standards set requirements for the quality of water intended for drinking purposes, as well as for PE pipes used in such applications. Are there no requirements regarding the anti-corrosion treatment of the inner walls of steel pipes used for supplying drinking water?
The interior of the drinking water container is coated with nylon powder, specifically PA11 powder; this material is widely used abroad. It can be used at temperatures below 80 degrees Celsius without any problems, and it also has antibacterial properties.
Electrostatic spraying uses non-toxic plastic powder; for a better quality option, choose AkzoNobel’s products, while the cheaper ones are from Qingdao Jindapeng. After spraying, an electric spark test can be used to check the result
