First of all, plastic storage tank has the advantages of relatively low price, light weight, convenient handling and installation, no rust and no chemical reaction to the stored liquid, and is suitable for storing some liquids without corrosive substances, such as water, food and cosmetics. In addition, plastic storage tank has good sealing performance, which can effectively prevent liquid leakage and pollution.
However, plastic storage tank also has some shortcomings. First, the corrosion resistance is poor, and some corrosive substances such as strong acid and alkali cannot be stored. Secondly, it has poor high temperature resistance, can't store high temperature liquid, and is easy to deform and crack. Finally, its service life is relatively short, which can only be used for 5- 10 years.
In contrast, stainless steel storage tanks have the advantages of strong corrosion resistance, good high temperature resistance, high temperature storage and long service life, which can be used for more than 20 years. In addition, stainless steel storage tanks also have good sealing performance and compression resistance, and can withstand greater pressure.
However, the disadvantages of stainless steel storage tanks are relatively high price, heavy weight, difficult handling and installation, easy to rust, and need regular maintenance, otherwise the quality of stored liquid will be affected.
To sum up, plastic storage tank and stainless steel storage tanks have their own advantages and disadvantages, and the choice of which storage tank should be decided according to the specific use scenario and the nature of the storage liquid. If some liquids containing no corrosive substances are stored, and the required price is relatively low, plastic storage tank can be selected; If storing some corrosive substances or high-temperature liquids requires a long life, you can choose stainless steel storage tanks.
