Dismantling of double layer oil storage tank equipment

When the construction projects of double-layer oil tank equipment renovation projects in various places are widely promoted, how to eliminate hidden safety hazards at construction sites and safety risks at construction sites? In the following, the main points of prevention and control at the construction site must be kept in mind!

1. Main points for the prevention, control and control of the removal of double-layer oil tank equipment: Remove the oil tanker's refueling machine gun, level gauge, submersible pump and other electrical equipment, disconnect the power supply side first, and then carry out the removal of the pressure vessel and properly storage. When removing the oil tank, use explosion-proof tools to carry out the development. After the road is removed, take measures to block it with water injection, and all the removal ports of the double-layer oil tank should be closed with blind plates. After the oil tank and connecting parts are removed, the returned oil is held in an aluminum container.

2. the main points of cleaning, control and treatment of double-layer oil tank equipment. The personnel should be equipped with work clothes, respirators, ventilation and drainage risers, lifelines, and aluminum ladders, and the fire equipment should be assigned to the designated location. Before cleaning the pressure vessel, blow air into the oil tank to reduce the oil and gas concentration value. Use a combustible gas detector to test the working environment of the oil tank. When the concentration of oil and gas is less than 0.25% and the oxygen content is 19.5% -21.5%, clean up the double-layer oil tank. The double-tank tank equipment cleaning operation is carried out within 30 minutes after the work ticket is signed. If the work is not performed for more than 30 minutes, the concentration needs to be re-measured and the work must be re-signed. The process pipeline is purged with water (or nitrogen) and the blind plate is blocked. The construction party carrying out the cleaning of the oil tanks shall have the corresponding qualifications.
