Currently , chemicals storage tanks, transport vessels and tankers chemical raw materials , mostly steel and stainless steel, stainless steel storage tanks suitable for most chemicals , but expensive. Carbon steel tanks with high strength, low cost advantages, but for many chemicals impatience corrosion , especially for iron content has required strict control of chemical raw materials , steel tanks can not store , nor can the ordinary carbon steel ship , tanker transport. For chemical storage and transportation companies , will be adjusted according to market varieties of chemical raw materials storage , this way , carbon steel tanks often can not meet the requirements , the objective is to limit the need for enterprise storage and transportation of chemical raw materials . I am using the metal spray coating + protection measures in carbon steel tanks, cabin , tank wall spray a layer of metal ( such as zinc alloy, stainless steel , etc. )
