Storage tank refers to the equipment used to store various liquid raw materials, semi-finished products or finished products. Also known as "storage tank". Due to the wide variety of storage media and storage conditions, there are different types of storage tanks. According to the material is divided into metal and non-metallic storage tank, metal storage tank is widely used, non-metallic storage tank is mainly used to store corrosion resistance requirements and low pressure medium. According to the structure shape is divided into cylindrical, spherical and non-circular cross-section (such as long round, rectangular) tanks, cylindrical tanks because of the easier manufacturing, the most widely used.

※Classification※
There are many types, generally: steel storage tanks, stainless steel storage tanks, rotomolding storage tanks, glass steel storage tanks, ceramic tanks, rubber storage tanks, welded plastic storage tanks, etc. As far as the cost performance of storage tanks is concerned, rotomolding storage tanks are now the most superior. rotomolding storage tanks can be divided into steel-lined plastic storage tanks and all-plastic storage tanks, including vertical, horizontal, transportation, mixing and other varieties respectively.

※Specifications※
Steel-lined plastic vertical storage tank Steel-plastic composite vertical storage tank Tortoise shell lined storage tank specifications are about 1 cubic to 180 cubic meters. Among them, polyethylene all-plastic storage tanks are vertical (flat bottom, cone bottom) and horizontal. Transport tanks include automobile transport tankers and carriage transport tanks. Mixing tanks have flat cover flat bottom, flat cover cone bottom, reaction tank type, steel lined plastic storage tanks, steel-plastic composite storage tanks have vertical (flat bottom, cone bottom), horizontal and other products. All kinds of tanks can also be customized according to requirements. Generally, the applicable size of the full plastic tank is about 1 cubic to 100 cubic meters.

※Processing technology※
(1) the processing technology of polyethylene storage tank: Polyethylene (PE) horizontal storage tank is made of pure polyethylene (linear low density polyethylene LLDPE, high density polyethylene HDPE) as raw material, and is integrally formed by rotational molding process.
(2) Processing technology of steel lined plastic storage tank: Steel-lined plastic vertical storage tank, also known as tortoise shell lining storage tank (tortoise shell lining-steel, mesh, plastic three-in-one) is the essence of steel-plastic composite products. It uses a special rotational molding process. It is the steel net (tortoise shell) welded to the surface of the steel body, with pure polyethylene (linear low density polyethylene LLDPE, high density polyethylene HDPE) as raw material, the use of rotational molding process of steel plate, steel net (tortoise shell) and polyethylene organic combination into one. Polyethylene firmly on the surface of the steel body. The product has the advantages of no welding seam, no leakage, no toxicity, anti-aging, impact resistance, corrosion resistance, long life, and compliance with health standards. It makes up for the shortcomings of all-plastic rotomolding storage tank with poor rigidity, no pressure resistance and poor temperature resistance. The inner lining surface of the product is flat, smooth and firm. Compared with the traditional steel-lined plastic plate storage tank, steel-lined rubber storage tank and steel-lined FRP storage tank, it has the advantages of better corrosion resistance, no leakage, no peeling, wear resistance, certain pressure resistance, higher temperature resistance and longer service life. Its price is lower than the traditional storage tank of the same specification, and it is an ideal container for storing corrosive liquids. Therefore, it is an extremely excellent corrosion-resistant storage tank.
