Why PPH storage tank Can replace stainless steel
PPH tank is a kind of plastic container, which, like stainless steel tank, is processed by rotational molding process and is used to store chemical liquid raw materials or finished raw materials. The enterprise shall have the corresponding qualification (industrial production license), equipment and construction personnel for the production and manufacturing of hazardous chemical storage tanks. If dangerous chemical storage tanks are not produced, there will be hidden dangers, ranging from property losses to accidents. Therefore, dangerous chemical storage tanks are the primary task of enterprises.
At present, there are carbon steel, aluminum, stainless steel, PPH, PVC, glass fiber reinforced plastic, composite materials and other materials in hazardous chemical storage tanks. The reason is that various media will cause certain corrosion to various materials, rather than any material can be filled with any medium. When selecting hazardous chemical storage tanks, materials with low corrosivity are selected as materials for hazardous chemical storage tanks. When purchasing storage tanks for hazardous chemicals, enterprises should consider not only safety but also price. At present, the most dangerous chemical tanks are stainless steel tanks, but stainless steel tanks usually have two conditions: high price and stainless steel corrosion. In this case, the company will also consider other materials.
Why does PPH tank replace stainless steel? The mechanical strength, service time, corrosion parameters and maintenance temperature of two kinds of dangerous chemical storage tanks were compared. The service life of stainless steel tank is generally 8-10 years, but the service life of stainless steel tank can reach 10-13 years; The mechanical strength of stainless steel tanks is higher than that of PPH tanks, but hazardous chemical tanks are generally static rather than high mechanical strength tanks; PPH tanks are resistant to most acids, alkalis and mixed liquids, and will not corrode as long as they are used within the specified temperature range, and many PPH tanks will corrode stainless steel (except special stainless steel) media;
PPH storage tank has become the equipment required by chemical industry, smelting, rare earth, mining, pigment, printing and dyeing, new materials, new energy, biomedicine and other industries, and some industries have been transformed into PPH material reactors.
