The connection of steel lined plastic storage tank shall be connected with full plastic flange. Attention shall be paid to the looseness during transportation or loading and unloading to avoid potential safety hazards Steel lined plastic storage tank is widely used in chemical, food, medicine and other industries. It can obtain higher strength and life through steel lined with plastic storage tank, with wide adaptability Steel lined plastic storage tank, also known as Gui Jia liner storage tank (Gui Jia lining steel, net, plastic three in one) is the essence of steel plastic composite products. It is welding steel mesh (Gui Jia) on the surface of steel, YISHION polyethylene (linear low density polyethylene LLDPE, high-density polyethylene HDPE) as raw material, using rotational molding technology to steel plate, steel mesh (Gui Jia) and polyethylene organic integration into one product. The advantages of welded joints, non leakage, non-toxic, anti-aging, impact resistance, corrosion resistance, long life and hygienic standards make up for the disadvantages of all plastic rotational molding tanks, such as poor rigidity, poor pressure resistance and temperature difference. The products are lined, smooth and firm, and have better corrosion resistance compared with traditional steel lined plastic plate storage tanks, steel lined rubber storage tanks and steel lined FRP tanks. , no leakage, no peeling, wear-resistant, can withstand certain pressure, can withstand higher temperature, longer life and other advantages, its price is lower than the same specification of the tank, is the ideal container for storing corrosive liquid.
