In addition to installation of new welded oil storage tanks, our field crews are experts at oil tank repairs. We can provide repairs ranging from coating renovation, shell patching, foundation repairs and new/replacement appurtenances. Our field teams are highly trained on safety processes involving oil storage tank repairs such as confined entry and other procedures.  Please visit our tank repairs for details on oil storage tank repair services we provide.

As STCI manufactures oil storage tanks, we can also directly supply original manufacturer equipment (OEM) parts and components when new or replacement parts are needed.  For a list of all available parts and components please visit our Parts & Accessories page.
