Catastrophic Failure of Storage Tanks (May 1997)

storage tanks have failed catastrophically when the flammable vapors inside an atmospheric tank exploded. The tank was either pr opelled upward from its base (shell-to-bottom seam failed) or split along the side seam. As a result, workers were killed or injured and Difference between Fiberglass and Polyethylene Water Tanks

  • Manufacturing ProcessConstructionCostMaintenanceHow to Weld HDPE HunkerWelding HDPE, or high-density polyethylene, is a normal procedure for joining lengths of pipe together, whether it be for industrial or home use. One of the benefits of welding HDPE plastics in smaller applications such as you might find in home plumbing systems is that no weld filler rod is necessary.
