PPH儲罐可以代替不銹鋼儲罐嗎？
PPH儲罐是一種滾塑工藝加工而成的塑料容器，和不銹鋼儲罐相同都是裝化工液體質料或成品質料的貯存容器，歸于危化品儲罐。企業出產制作危化品儲罐要有相應的資質（全國工業產品出產許可證）、設備及專業施工人員，若短少任何一個制作出的危化品儲罐都會有隱患存在，輕則財產損失，重則產生重大事故，所以危化品儲罐是企業重中之重。
現今市場上呈現的危化品儲罐原料有碳鋼、鋁、不銹鋼、PPH、PVC、玻璃鋼及復合資料等，之所以會呈現這么多種原料，是因每種介質對各種原料都會存在必定的腐蝕，不是說任何一種資料都能夠盛裝任何的介質，在選擇危化品儲罐時要選擇腐蝕量比較小的原料作為該危化品儲罐資料。企業在購買危化品儲罐時，不只會考慮安全因素，還會在意價格的因素。
現在運用比較多的危化品儲罐就是不銹鋼儲罐，但往往不銹鋼儲罐存在價格高或不銹鋼產生腐蝕這2種狀況，當企業碰到這類狀況時就會考慮其他原料，而PPH儲罐成為替代不銹鋼儲罐的推薦，不只因價格遠低于不銹鋼儲罐，還有其方面。
為何PPH儲罐能夠替代不銹鋼？比較2種危化品儲罐，都是從機械強度、運用壽命、腐蝕參數、保護狀況、運用溫度等方面做對比。
PPH儲罐出廠運用年限正常在8-10年左右，而不銹鋼儲罐比較多10-13年；不銹鋼儲罐機械強度高于PPH儲罐，但危化品儲罐一般為靜態放置，不必高機械強度的儲罐；
PPH儲罐耐大多數酸、堿、有機物、混合液，只需保證運用溫度在限定范圍內，都不會存在腐蝕狀況，而很多PPH儲罐能夠耐的介質對不銹鋼會存在腐蝕（特種不銹鋼在外）；保護方面PPH儲罐保護簡單，工具簡易，廠家能夠自行處理；危化品運用溫度一般為常溫，PPH儲罐比較高運用溫度能夠到100℃。
PPH儲罐已經成為化工、冶煉、稀土、礦山、顏料、印染、新資料、新能源、生物醫藥的必備設備，甚至有部分職業已經在一部分運用條件為常溫常壓的不銹鋼反應釜改為PPH原料制作的反應釜。PPH儲罐在比較近幾年內會得到廣泛應用。
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.
