Step 1: Preparation
Before starting any repair work on the diesel storage tank, safety must be the top priority. First, empty the tank completely and transfer the diesel to a safe storage facility. Then, use appropriate ventilation equipment to remove any remaining diesel fumes from the tank. Wear protective gear, including safety goggles, gloves, and a respirator.
Step 2: Inspection
Inspect the tank thoroughly to identify the problems. Check for signs of rust, corrosion, dents, or leaks. Use a flashlight to examine the interior and exterior of the tank carefully. Small leaks can be detected by applying a soapy water solution to the suspected areas and looking for bubbles.
Step 3: Surface Preparation
For areas with rust or corrosion, use sandpaper or a wire brush to remove the rusty layers until the bare metal is exposed. This step ensures better adhesion of the repair materials. Clean the surface with a degreaser to remove any oil or dirt.
Step 4: Repairing Small Leaks and Holes
For small leaks and holes, use an epoxy putty. Knead the putty according to the manufacturer's instructions and apply it firmly over the damaged area. Press it down well to ensure a tight seal. Let it cure for the recommended time.
Step 5: Repairing Larger Damages
If there are larger dents or holes, a patch may be required. Cut a piece of metal that is slightly larger than the damaged area. Clean and prime both the patch and the surrounding area of the tank. Use welding equipment to attach the patch securely if the tank material allows for welding. If not, use a strong adhesive designed for metal repairs.
Step 6: Testing
After the repair is complete, conduct a leak test. Fill the tank with water and let it sit for a few hours. Check the repaired areas for any signs of leakage. If no leaks are detected, the tank is ready for use.
