It is necessary to install a water heater in the bathroom. Without a water heater, we can' t take a bath. The most important thing of the water heater is the inner tank. The quality of the inner tank must be good. If the inner tank is broken, the whole water heater must be replaced. The following editor will introduce to us whether the stainless steel inner tank or the enamel inner tank of the electric water heater is better.

There are two main types of liners:

Although there are many kinds of materials for the inner tank of electric water heater, in fact, the inner tank of electric water heater mainly includes stainless steel and enamel. The so-called titanium gold liner, Jingui liner, quartz enamel, sapphire, and so on, are simply plating or adding rare metals to these two main materials, which is a different name.

Stainless steel liner

The advantages of stainless steel liner are good liner material and high strength; High temperature and corrosion resistance; It has stable performance and is not easy to rust, but it is difficult to weld. The biggest hidden danger is the weld. In the process flow, false welding is easy to occur and is not easy to be found. It is easy to rust and leak water between the welds with a little longer time, and the false welding part cannot be inspected before delivery. In order to reduce the production cost, some manufacturers use very thin stainless steel, which reduces the pressure of the liner and affects the service life. In addition, there is a kind of crystalline silicon inner liner, which is actually improved on the basis of stainless steel inner liner. The latest technology is selected on the basis of steel plate. The silicide is baked at 900 ℃ to make it adhere to the inner and outer walls of the inner liner, which can block water from the inner liner and prevent direct contact between water and steel plate. It has the advantages of no rusting and high strength.

Enamel liner

Most manufacturers in the market now use enamel liners. There is a layer of enamel on the surface of the enamel inner tank, which is free of rust and scale, and has strong pressure resistance. However, the low-grade carbon steel plate used for the general enamel liner has only two layers of liner, which has many problems such as fish scale explosion, acid corrosion and fast dissolution, and its service life is low. Attention should also be paid to the selection of enamel liner. The quality of enamel liner mainly depends on the processing technology. Ariston' s titanium inner liner and AO Smith' s Jingui inner liner are improved enamel inner liners, which not only have good corrosion resistance, but also have high strength, high temperature resistance, corrosion resistance and stable performance. Haier' s diamond three-layer bladder is also made of enamel technology, which greatly improves the resistance to dissolution, explosion and acid, and then extends the service life of the water heater.

The above is the introduction of stainless steel and enamel liners of electric water heaters. From the above content, we can see that stainless steel liners are more stable and durable than enamel liners. However, some manufacturers have very good technology, so they will make enamel liners better than stainless steel ones. Therefore, we should be optimistic about the brands when selecting water heater liners. I hope the above content can help us.
