Stainless steel tanks, as an important storage equipment, are widely used in chemical, food, pharmaceutical and other industries. However, in some environments, stainless steel storage tanks also face corrosion problems. In order to extend to improve its anti-corrosion function is particularly important. In this paper, we will discuss how to improve the anti-corrosion function of stainless steel storage tanks.

First, choose the right stainless steel material

Stainless steel is a highly corrosion-resistant metal, but different types of stainless steel materials have different corrosion resistance, therefore, when choosing stainless steel tanks, you should choose the appropriate stainless steel material according to the use of the environment. For example, in a strong acid environment, you should choose a highly acid-resistant stainless steel material, such as 316L or 304, etc.

Second, strengthen the structural design

The structural design of stainless steel storage tanks also has an important impact on its anti-seat function. Reasonable structural design can effectively reduce the occurrence of corrosion. Here are some ways to improve the structural design.

1, avoid dead ends: in the structural design, should try to avoid dead ends, so as not to accumulate black impurities and corrosion products.

2, reduce the gap: the gap is easy to corrosive bacteria breeding place, so should try to reduce the gap, improve the overall sealing of the equipment.

3, a reasonable set of ventilation holes: ventilation holes can prevent negative pressure inside the equipment, is conducive to the maintenance of equipment and maintenance. However, the location of the vent should be set up reasonably, so as to avoid rain and other impurities into the internal equipment.

Third, the surface treatment

Stainless steel tank surface treatment is also an important means to improve the anti-corrosion function. The following are some methods of surface treatment.

1, polishing: polishing of stainless steel tanks can remove surface impurities and oxidized layer, improve surface corrosion resistance.

2, spray anti-corrosion coating: spray anti-corrosion coating on the surface of stainless steel tanks can effectively isolate the equipment from contact with the external environment, reducing the occurrence of corrosion. Commonly used anti-corrosion coatings are epoxy resin polyurethane vinegar and so on.
