STEP #4
Shaping Steel
Approximate Time In Stage: 1 to 3 Days
Rolling Tank Sections
Flat sheets of up to .375” steel are rolled into perfect circles and ends are stitch welded together. We then angle grind outer seem to allow for a full penetration weld. The inner stitch weld is then replaced with a redundant & full penetration flux core weld.
Our rolling process accommodates an outer tank diameter from 4’ to 12’.
Joggle Process
Most tank manufacturers connect the individual shells of their above-ground storage tanks using a cheaper buttweld method and others use a non-uniform lap joint weld. Our joggle weld process achieves an even more uniform and smoother than the butt-weld while providing superior integrity compared to the lap-joint weld.
While joggle welded tank shells require more work, our quality standards demand this superior method. While this Envirosafe™ process requires a little more time and labor the results enable our turn-key systems to be relocated numerous times without fear of leaks. We build above-ground fueling systems that are almost seamless and able to survive for decades.
