Regular and proper maintenance of diesel storage tanks is essential to ensure their safe and efficient operation, as well as to extend their lifespan.
Visual inspections should be carried out frequently. Examine the tank's exterior for any signs of corrosion, which can be indicated by rust spots or discoloration. Even small areas of corrosion can, over time, lead to leaks if left unaddressed. Check for dents or physical damage that might have occurred due to external impacts. For underground tanks, monitor the soil around the tank for any signs of wetness or abnormal vegetation growth, as these could suggest a leak.
The tank's interior also requires attention. Periodically, drain a small amount of diesel from the bottom of the tank to check for water or sediment accumulation. Water in the tank can cause corrosion from the inside and also lead to engine problems if it gets into the fuel system. Sediment can clog filters and disrupt the smooth flow of diesel. If significant amounts of water or sediment are found, the tank may need to be fully drained and cleaned.
Valves, vents, and gauges are crucial components that need regular maintenance. Test the valves to ensure they open and close properly. A malfunctioning valve can lead to over - pressure situations or prevent the proper transfer of diesel. Vents should be kept clear to allow for the safe release of pressure. Clogged vents can cause the tank to build up excessive pressure, increasing the risk of an explosion. Gauges, such as fuel level gauges, should be calibrated regularly to provide accurate readings.
The area around the tank must be maintained as well. Keep it clean and free from debris, weeds, and flammable materials. This not only reduces the fire risk but also makes it easier to access the tank for inspections and maintenance. Additionally, ensure that any secondary containment structures, such as spill pallets or berms, are in good condition. They are designed to contain spills in case of a leak, and if they are damaged, they may not function effectively. By following these comprehensive maintenance methods, diesel storage tanks can operate safely and reliably for many years.
