In recent years, with the rapid development and progress of the petroleum industry, the amount of energy utilization is also increasing rapidly. The key part of petroleum transportation is the oil storage system, and the technology used in the construction of storage tanks is the prerequisite to ensure its normal operation. Before the construction of the oil storage tank, technicians are required to comprehensively consider the problems involved in the construction and systematically consider the problems, so as to ensure that the oil storage tank can play its due role in use.
The construction process of oil storage tank
1. Excavation of oil storage tank pool
Before the installation of underground oil storage tanks, first of all, it is necessary to carry out the construction of oil tank pools according to the requirements. Generally, the inner diameter of oil storage tanks in gas stations should be kept at 2.5m, and the depth of oil storage tanks should be kept at 4m. This index requirement is mainly to ensure the depth of oil storage tanks and the stability of the foundation. In the actual construction process, construction workers should strictly follow the technical standards and strictly handle all kinds of operation bills. In the construction of an oil storage tank, the construction unit needs to work strictly according to safety standards to ensure the safety of every worker. Before construction, it is necessary to systematically analyze the possible safety problems in the construction and find out the countermeasures. Only through systematic training can the construction personnel carry out the construction operation.
2. Hoist the oil tank
Hoisting the oil storage tank into the oil storage tank after the basic construction of the oil storage tank is completed, which is a type of hoisting operation. Before construction, it is necessary to strictly examine the qualifications of the construction unit, including the skill level of the staff of the construction unit and the specific scheme of the construction project. If any safety accident occurs during construction, the construction unit should bear corresponding responsibilities. Before the crane is constructed, it is necessary to specify the on-site commander, which can ensure that the on-site staff can quickly find the commander. During construction, operators are required to strictly follow the operating rules and carry out the construction work according to specific operating signals. On-site construction personnel should master the specific construction requirements in detail. If there is any problem in the construction scheme, timely communication is required to ensure that the construction meets the safety technical standards.
Problems existing in the new construction of oil storage tanks and their solutions
1. Oil storage tank pipeline equipment
Due to the special requirements of oil storage tanks, the stored substances will cause corrosion of tanks under the action of the outside world. In severe cases, it will cause the danger of gas leakage, fire or explosion, resulting in the loss of life and property. Corrosion is the main reason for the leakage of oil pipelines and oil storage tanks. Investigation and analysis by scientific research institutions have found that pipeline corrosion mainly causes safety accidents from the inside. The internal corrosion of oil storage tanks is a common phenomenon, and external corrosion is affected by a wide range of factors. The common soil corrosion, electrochemical corrosion and the lack of corrosion resistance of materials need to be implemented. Before construction, it is necessary to analyze the anti-corrosion strategy system, and anti-corrosion work should be carried out for key parts according to the strategy. At present, with the development and progress of urbanization in China, the scale of cities is constantly expanding. Before the construction of oil pipelines and oil storage tanks, it is necessary to fully consider these issues, keep a safe distance in design, and avoid the conflict between urban expansion and oil storage pipelines.
2. Welding of oil storage tanks
The welding process is the key factor in the construction of oil storage tanks, and the welding quality will have a significant impact on the quality of subsequent oil storage tanks. Therefore, improving the welding quality is the key factor to realizing the long-term and stable operation of the oil storage tank, including the welder, labor protection articles and welding auxiliary facilities. Before welding, it is necessary to inspect the welding equipment to ensure that all kinds of equipment are in the best condition, which can ensure the smooth implementation of oil storage facilities. The external climatic conditions for welding are in a low state, so it is necessary to preheat the equipment used before welding. On-site technicians need to make technical disclosure to the construction personnel to ensure the smooth progress of the construction. In addition, before the welding work, the staff should clean up the rust and oil around the welding according to the actual situation, so as to avoid the influence of external factors on the welding equipment. The welding current and welding speed should be strictly controlled, and the used current and the type and model of covered electrode all meet the technical standards. In the process of oil tank welding, the uniform welding method will be chosen. The advantages of the welding method are that the width of the welding gap is uniform and the thickness of the welding seam can be uniform.
To sum up, with economic development and progress, the country’s energy consumption is also increasing. In the process of oil storage tank construction, it is necessary to master the safety and technical standards in detail to ensure that the preparatory work before construction meets the technical requirements. In addition, the welding process of the key parts of the oil storage tank should be strictly managed to avoid leakage due to an unqualified welding process, resulting in property losses and potential safety hazards.
