The reason why PP winding storage tank can replace stainless steel
PP winding storage tank is a plastic container formed by winding and extrusion. Like stainless steel storage tank, it is a storage container for chemical liquid raw materials or finished raw materials. It belongs to hazardous chemical storage tank. Enterprises producing and manufacturing dangerous chemical storage tanks should have corresponding qualifications, equipment and construction personnel. If the dangerous chemical storage tanks produced will have hidden dangers, minor property losses and serious accidents, the dangerous chemical storage tanks are the top priority of enterprises. PPH storage tank
At present, the materials of dangerous chemical storage tanks on the market include carbon steel, aluminum, stainless steel, PP, PVC, FRP and composite materials. The reason why there are so many materials is that each medium will corrode various materials to a certain extent. This does not mean that all materials can contain media. In the selection of hazardous chemical storage tank, materials with less corrosion shall be selected as the materials of hazardous chemical storage tank. When purchasing storage tanks for hazardous chemicals, enterprises should consider not only safety factors, but also price factors. At present, stainless steel tanks are used as storage tanks, but usually the price of stainless steel tanks is high or stainless steel corrosion occurs in two cases. When enterprises encounter this situation, they will consider other materials and PP lines to replace stainless steel tanks. Storage tanks are not only cheaper than stainless steel tanks, but also have other aspects.
Why can PP winding tank replace stainless steel? The two kinds of dangerous chemical storage tanks are compared in terms of mechanical strength, service life, corrosion parameters, maintenance, service temperature, etc. The factory service life of PP wound storage tank is generally about 8-10 years, while the service life of stainless steel storage tank is 10-13 years. The mechanical strength of stainless steel storage tank is higher than that of PP wound storage tank, but the storage tank for hazardous chemicals is generally statically placed and the mechanical strength is not high; PP winding tanks are resistant to most acids, alkalis and mixed liquids. As long as the operating temperature is within a limited range, there will be no corrosion, and many PP winding tanks can resist the corrosion of medium stainless steel (except special stainless steel); The maintenance of PP winding tank is convenient, the tools are simple, and the manufacturer can handle it; The use temperature of hazardous chemicals is normal temperature, and the high use temperature of PP winding storage tank can reach 100 ℃.
PP winding slot has become a necessary equipment. Chemical industry, smelting, rare earth, mining, pigments, printing and dyeing, new materials, new energy, biomedicine, and even some industries have changed the reaction kettle and stainless steel reaction kettle of materials at room temperature and pressure. PP wound storage tank will be widely used in the next few years.
