This double-walled safety storage tank is specially designed for the temporary storage of waste oil containing impurities and moisture or crude oil awaiting treatment. It adopts a "tank within a tank" explosion-proof and leak-proof structure to ensure absolute safety and environmental compliance in liquid storage.
Core Features
• Double-layer explosion-proof structure : It adopts a double-layer design with a carbon steel SFL main tank and a secondary carbon steel outer tank (or MDPE material). The outer tank acts as a safety dike. Even if the inner tank leaks, the waste oil will be completely collected in the outer tank, preventing environmental pollution.
• Conical bottom slag discharge design : The tank bottom adopts a conical structure and is equipped with a large-diameter slag discharge valve. The heavier oil sludge, water and impurities can settle naturally and be discharged automatically, which is convenient for subsequent cleaning.
• Intelligent monitoring accessories : Equipped with electronic level gauges, overflow protection valves and dike monitors, it can monitor the liquid level in the tank in real time and prevent oil spill accidents.
• Corrosion resistant and durable : The tank body is made of heavy-duty anti-corrosion process or medium-density polyethylene (MDPE) molding, which is lightweight, resistant to acid and alkali corrosion, and will not rust after long-term use.
Product Advantages
• Environmental compliance : It fully complies with the strict regulations of environmental protection departments on the storage of waste oil and sludge oil. The integrated cofferdam design eliminates the cumbersome and costly traditional civil engineering cofferdams.
• Sedimentation separation : Utilizing the principle of natural sedimentation due to gravity, water and solid impurities in waste oil can be initially separated, reducing the load on subsequent oil recovery or treatment.
• Safe and reliable : The heavy-duty locking cover and multiple safety valve design effectively prevent rainwater backflow and oil and gas evaporation, ensuring safe storage.
