The hot water system in modern multistory buildings exposed to internal corrosion due to the low quality of the internal protective coating violation welding technology, and more. It is for these systems developed electrochemical series magnesium plants protection from internal corrosion of pipelines shield. Protection against corrosion of internal surfaces of pipes PRT is made due to the formation on the surface that koroduye resistant films with products of anodic dissolution and precipitation of magnesium alloys hardness that stand out from the water. Dissolution of the anode current and, consequently, the degree of protection is governed by the terms of the corrosion rate and flow of water in the DHW system.
