However, in the use process of the electric water heater, the corrosion problem of the electric heating pipe has always been a difficult problem for water heater manufacturers and consumers.

[0003] At present, the mainstream electric water heater heating pipe on the market is mostly made of nickel-based alloy stainless steel material. Although this material has certain corrosion resistance, the surface of the heating pipe is still prone to corrosion in the process of long-term contact and heating with tap water containing Ca²⁺, Mg²⁺, Cl⁻ and other ions.
