Why can industrial pickling tank replace stainless steel?
Industrial pickling tank is a kind of plastic container processed by rolling plastic process. Like stainless steel pickling tank, it is a storage container for chemical liquid raw material or finished product raw material, belonging to the pickling tank for dangerous chemicals. The acid pickling tank for hazardous chemicals produced by an enterprise shall have corresponding qualifications (national industrial product production license), equipment and professional construction personnel. If any of the acid pickling tanks produced by the enterprise is lack, there will be hidden dangers, which may cause property losses or major accidents. Therefore, the acid pickling tank for hazardous chemicals is the most important one of the enterprises.
The pickling tanks for hazardous chemicals in the market today are made of carbon steel, aluminum, stainless steel, PPH, PVC, glass fiber reinforced plastics and composite materials. The reason why there are so many kinds of materials is that each medium has certain corrosion to all kinds of materials, not that any kind of material can contain any medium. When choosing the pickling tanks for hazardous chemicals, the materials with the least corrosion should be selected It is the material of pickling tank for hazardous chemicals. When purchasing pickling tanks for hazardous chemicals, enterprises will not only consider safety factors, but also pay attention to price factors. At present, the most used pickling tank for hazardous chemicals is stainless steel pickling tank, but there are often two situations of high price or corrosion of stainless steel in stainless steel pickling tank. When enterprises encounter such situations, they will consider other materials, and industrial pickling tank becomes the first choice to replace stainless steel pickling tank, not only because the price is far lower than stainless steel pickling tank, but also because of its aspects.
Why can industrial pickling tank replace stainless steel? The comparison of two kinds of pickling tanks for hazardous chemicals is made in terms of mechanical strength, service life, corrosion parameters, maintenance, service temperature, etc. The factory service life of industrial pickling tank is normally about 8-10 years, while that of stainless steel pickling tank is at most 10-13 years; the mechanical strength of stainless steel pickling tank is higher than that of industrial pickling tank, but the pickling tank for hazardous chemicals is generally placed statically, and high mechanical strength pickling tank is not used; the industrial pickling tank is resistant to most acids, alkalis, organics and mixtures, as long as the service temperature is within the limited range, it will not There is corrosion, and many industrial pickling tanks can resist the medium corrosion of stainless steel (except for special stainless steel); maintenance of industrial pickling tanks is simple, simple tools, and the manufacturer can handle by itself; the use temperature of hazardous chemicals is generally normal temperature, and the maximum use temperature of industrial pickling tanks can reach 100 ℃.
Industrial acid pickling tank has become a necessary equipment for chemical industry, smelting, rare earth, mining, pigment, printing and dyeing, new materials, new energy, biomedicine, and even some industries have changed the stainless steel reactor with normal temperature and pressure to PPH reactor. Industrial pickling tank will be widely used in recent years.
