Underground Storage Tanks - Yale

The use of underground storage tanks (USTs) for fuels and other liquids has many advantages. is called cathodic protection.Steel structures are considered protected if a current with 0.85 volts is created from the surrounding soil to the tank.

Design and Installation Aspects of Cathodic Protection

Why cathodic protection is required for plant piping,mounded bullets and storage tank bottoms; Integrity of buried plant piping carrying fire water,cooling water,waste water,raw water,product etc is very important for safe operation of the plant.The underground pipeline coating is not robust so cathodic protection is required to protect DESIGN RECOMMENDATION FOR STORAGE TANKSthe storage of water,spherical tanks (pressure vessels) for the storage of high pressure liquefied gases,and under-ground tanks for the storage of water and oil. as well as the Ds value of an anchored cylindrical steel-wall tank.As the number of smaller under-ground tanks used for the storage of water and fuel isCathodic protection of underground storage tankWhat procedures are used for cathodic protection testing? 1Advance notification to the MPCA of CP testing is not required.The CP tester must evaluate the CP system according to NACE RP0285,Corrosion Control of Underground Storage Tank Systems by Cathodic Protection. At least three test points per tank and per piping run must be utilized.
