The tank structure should be reasonably designed to avoid stress concentration, which is a major cause of cracks and leakage. Smooth transitions should be adopted at connections and corners, and appropriate reinforcement measures should be taken for key parts.

Meanwhile, the design should fully consider the working environment of the tank, such as pressure, temperature changes, and external impacts, to ensure that the structure can withstand various harsh conditions during use.

The steel used for diesel fuel tanks must meet relevant quality standards and have excellent corrosion resistance, tensile strength, and impact toughness. It is necessary to avoid using inferior steel materials that are prone to corrosion and deformation.

In addition, for tanks used in harsh corrosive environments, additional anti-corrosion materials or coatings can be selected to enhance the overall corrosion resistance of the tank.

During the manufacturing process, standardized operating procedures should be followed to ensure the quality of welding, forming, and other key processes. Welding is a critical link; the welding process must be stable, and the welds should be full and free of defects such as porosity, slag inclusion, and incomplete penetration.

After welding, non-destructive testing should be carried out to detect potential welding defects in a timely manner and repair them. The forming process should avoid excessive deformation of the steel plate, which may lead to material fatigue and subsequent leakage.

Regular inspection of the tank surface, welds, valves, and other components is essential. It is necessary to check for signs of corrosion, cracks, bulges, or oil seepage.

For the anti-corrosion coating on the tank surface, if peeling, cracking, or falling off is found, it should be repaired or re-coated in time. In addition, regular cleaning of the tank interior is required to remove impurities and sediment that may accelerate corrosion. The valves and seals should be checked regularly and replaced in time if they are found to be aging or damaged.

During the use of the tank, it is necessary to avoid overfilling, which may cause excessive pressure inside the tank and lead to leakage. At the same time, avoid violent collisions or impacts on the tank.

Reasonable storage and transportation measures should be taken to prevent the tank from being damaged by external forces. Establish a complete use and maintenance record system to track the status of the tank and ensure that all maintenance and inspection work is carried out in place.
