As the core facility for material storage in industrial production, the operation safety and stability of storage tanks are directly related to the production order and property safety of enterprises. Mastering scientific maintenance techniques is the key to extending the service life of storage tanks and preventing risks such as leaks.
1、 It is necessary to conduct weekly visual inspections of the tank body, head, welds, and other parts, with a focus on checking for deformation, cracks, rust spots, and leakage marks. If paint peeling or partial corrosion is found, the corroded area should be cleaned up in a timely manner and anti-corrosion coating should be applied. For buried storage tanks, it is also necessary to check the surrounding ground for settlement and oil leakage; For outdoor storage tanks, it is necessary to regularly clean the debris around the top and skirt of the tank, check whether the connection of the lightning protection grounding device is firm, and ensure that the grounding resistance meets safety standards (generally not greater than 10 Ω).
2、 Real time monitoring of tank operating parameters using level gauges, pressure gauges, and other instruments to ensure that the liquid level does not exceed the safe volume and the pressure is maintained within the specified range. Daily recording of liquid level and pressure data, comparative analysis of changing trends. If there are abnormal fluctuations (such as sudden rise and fall of liquid level or abnormal increase of pressure), it is necessary to immediately investigate whether there are problems such as excessive feeding, blocked discharge, or seal failure. At the same time, regularly calibrate the liquid level gauge and pressure gauge to ensure the measurement accuracy of the instrument and avoid misjudgment caused by instrument misalignment.
3、 Based on the characteristics of the storage medium in the tank, a reasonable cleaning cycle should be established, and internal cleaning should generally be carried out at least once a year. Before cleaning the tank, the medium must be thoroughly emptied, replaced and purged. Only after passing the inspection can the tank be operated to remove sediment at the bottom, scale and impurities on the inner wall, and prevent medium pollution or corrosion of the tank. In addition, it is strictly prohibited to mix media of different properties. When storing volatile and flammable media, it is necessary to ensure that safety accessories such as tank breathing valves and flame arresters are intact, and regularly check their opening flexibility and sealing to prevent media leakage from causing safety accidents.
4、 Regularly inspect the sealing parts of the manhole, flange, valve, etc. of the storage tank, replace aging and ineffective gaskets and sealing rings, and ensure a tight seal. For safety accessories such as safety valves and emergency shut-off valves, regular calibration should be carried out according to specifications to ensure that they can operate normally in emergency situations. Through systematic maintenance techniques, the operational reliability of storage tank equipment can be effectively improved, laying a solid defense line for enterprise safety production.
