Frangible roof welded steel tanks for oi storage

frangible roof tank as per api 650 - API (American

A tank with a diameter of 7m (23'-0) cannot have a frangible roof per 5.10.2.6.You will be required to provide a vent capable of relieving the emergency venting set forth in API 2000.To illustrate this,calculate the maximum area permitted for shell-to-roof reinforcement per 5.10.2.6(a)(5).Welded Steel Tank Manufacturer CST IndustriesWelded Tank Capabilities.CSTs reputation as the world leader in factory coated tanks goes beyond just field-assembled tanks.CST also manufactures factory coated welded tanks.Unlike field welded and painted tanks,CST welded steel tanks are fabricated in a modern,indoor,controlled environment.Venting Aboveground Tanks Part 2 - Getting the ProperJun 01,2000 Frangible roof welded steel tanks for oi storage#0183;For this reason,it is highly recommended that asphalt tanks have frangible roof designs whenever possible.The owner must decide how frequently to check and clean the parts for these devices.Some facilities inspect them monthly,which seems to work for many asphalt tanks.

Pressure relief can be achieved either by additional emergency venting or by designing the roof to shell joint as frangible (this means,principally,that the size of the fillet weld between the roof and the shell is limited in size - a limit of 5 mm is typical).
