PPH storage tank is a plastic container made of rolling plastic process, and stainless steel storage tank is the same as the storage container containing chemical liquid material or finished material, belongs to the dangerous chemical storage tank. Enterprises should have corresponding qualifications (national industrial product production license), equipment and professional construction personnel to produce dangerous chemical storage tanks. If any of the dangerous chemical storage tanks produced are short, there will be hidden dangers, including property losses or serious accidents. Therefore, dangerous chemical storage tanks are the top priority of enterprises.
There are carbon steel, aluminum, stainless steel, PPH, PVC, FRP and composite materials on the market today. The reason why there are so many kinds of raw materials is that each medium will have certain corrosion on all kinds of raw materials. It is not to say that any kind of material can contain any medium. In the selection of dangerous chemical storage tank to choose the least corrosion of the raw material as the dangerous chemical storage tank data. When buying dangerous chemical storage tanks, enterprises will not only consider safety factors, but also pay attention to price factors.
Most often used now for storage tank is stainless steel storage tank, but there often stainless steel tank price is high or stainless steel corrosion caused these two conditions, when the enterprise encounters this kind of situation will consider other raw materials, and PPH become first choice to replace stainless steel storage tank, storage tank is not only because the price is far lower than the stainless steel storage tank, and its aspects.
Why PPH tanks can replace stainless steel? The comparison of two kinds of dangerous chemical storage tanks is made from the aspects of mechanical strength, service life, corrosion parameters, protection status, service temperature and so on.
PPH storage tank factory service life is normally about 8-10 years, and stainless steel storage tank up to 10-13 years; The mechanical strength of stainless steel storage tank is higher than that of PPH storage tank, but the dangerous chemical storage tank is generally static placement, there is no need for high mechanical strength storage tank;
PPH tank resistance to most acid, alkali, organic matter, mixed liquid, only to ensure that the use of temperature in a limited range, there will be no corrosion, and many PPH tanks can withstand the medium of stainless steel will have corrosion (special stainless steel outside); Protection PPH tank protection is simple, simple tools, manufacturers can handle; The operating temperature of dangerous chemicals is generally normal temperature, and the highest operating temperature of PPH storage tank can reach 100℃.
PPH storage tank has become necessary equipment for chemical industry, smelting, rare earth, mining, pigment, printing and dyeing, new data, new energy, biological medicine, and even some occupations have changed the reaction kettle made of PPH raw materials in part of the stainless steel reaction kettle under normal temperature and pressure. PPH tanks will be widely used in the next few years.
