Heating tube heating method
The true explanation of scale
Firstly, you should have a clear understanding of what scale is. Many companies avoid the problem of scale formation in traditional metal electric heating and intentionally interpret scale as a decomposition product such as calcium bicarbonate in hard water. In fact, this is very one-sided. True scale is a slow oxidation reaction between metal surfaces and metal ions in water at a certain temperature, forming metal oxides on the metal surface. This layer of metal oxide is the true "scale". What are the consequences of scaling? Mild cases can greatly reduce thermal efficiency, consume electricity but not heat water, while severe cases can corrode metal and damage insulation, resulting in serious leakage hazards.
(In appearance, there are tubes or mainly, and those with the concept of stir frying are also called chromium heating wires (N). In fact, all this heating method is nickel chromium heating wires, which is not fundamentally different from copper heating pipes on the market.). Its advantages are low cost and easy procurement. Its disadvantage is that the metal surface is prone to scale and cause hidden dangers such as electric leakage, which usually show obvious signs after one to two years of use; Short lifespan, the internal nickel chromium heating wire is prone to oxidation, becoming brittle and easily breaking; Unstable power is prone to power degradation
