Stainless steel storage tanks are essential and important basic equipment for petroleum, chemical industry, grain and oil, food, fire protection, transportation, metallurgy, national defense and other industries. Our economic life is always inseparable from large and small stainless steel storage tanks. The important role played by stainless steel storage tanks in the development of the national economy is irreplaceable. For many enterprises, it is impossible to produce normally without storage tanks, especially the national strategic material reserves are inseparable from various capacities and types of stainless steel storage tanks.
Polyethylene is referred to as PE. The highest application temperature is 60 ℃ for low density polyethylene and 70 ℃ for high density polyethylene. The minimum application temperature is -70 ℃. It 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 poor rigidity, no pressure resistance and poor temperature resistance of all-plastic rotomolding storage tanks. 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, longer service life, etc. Its price is lower than that of the traditional storage tank of the same specification, and it is an ideal container for storing corrosive liquid. Therefore, it is an extremely excellent corrosion-resistant storage tank. The steel-lined plastic vertical storage tank also has the characteristics of convenient installation, small footprint, and can be made into the shape required by users. The integrity of oversize steel-lined plastic storage tanks is more prominent, which is not achieved by other storage tank manufacturing processes.
For the production of small quantities of plastic products, the mold for rotational molding is not affected by external forces, so the mold is simple, inexpensive and easy to manufacture. In addition, rotational molding equipment also has greater mobility. A rotational molding machine can install a large mold or arrange multiple small molds. It can not only mold parts of different sizes, but also mold products of very different sizes and shapes at the same time, as long as the raw materials used in rotational molding products are the same.
