According to this management concept, the gas production and management should be analyzed and studied before the anti-corrosion construction of the gas storage tank, and the external anti-corrosion should be clarified. Construction management objectives On this basis, the construction management system is analyzed. Through the previous construction management work, the shortcomings in the construction management system are understood. At the same time, in view of the construction requirements of the external anti-corrosion construction of the gas storage tank, the existing construction management system is carried out. The defects in the construction management and the construction management system of the external anti-corrosion construction management requirements of the gas storage tank are used to regulate the external preservation of the gas storage tank. Construction management work and promotion of management objectives. On the basis of doing a good job in the construction management system, the external anti-corrosion materials and construction techniques should be discussed.
