Tank Inspection, Repair, Alteration and Reconstruction
API 653
Minimum structural t-min applied to pressure vessels and tank shells
0.1"
Reassessed Limit Thickness
The 'S' in 5S and 10S
Stainless
Used to be a scuba diver instructor
Tim
Need both: Design Code and Inspection Code for Pressure Process Piping
ASME B31.3 & API 570
Additional material thickness available to allow for metal loss during the service life of the vessel component.
Corrosion Allowance
This level is used to capture Design Temperature & Design Pressure
Chambers
( tprevious - tactual ) / time between tprevious & tactual
Short Term Corrosion Rate
Worked as a roofing consultant for 12 years
Ahnna
Fitness-for-Service
API 579
Requires a knuckle and crown radius for t-min calc
Torispherical Head
Name of the Corrosion Monitoring Report we run within Antea
Flash Report by CML Point
Portion of the tank floor within 3" of the inside edge of the shell, measured radially inward
Critical zone

Derrick
Alternative Rules for Construction of Pressure Vessels
ASME Sec 8 Div 2
Design Pressure, Radius/Diameter, Allowable Stress, JE, Supplemental Thickness (optional)
1. Reclassified component (has a FFS t-min)
2. Has Operation
( tactual - tmin ) / corrosion rate
Remaining Life
Used to trick-or-treat at Eminem's house

Why ASME Sec 8 Div 1 materials are split between Pre-1999 and Post-1998?
Safety factor changed from 4 to 3.5
Criteria required to not calculate a piping pressure t-min?
Below 500F, Below 500psi, AND 6" NPS or less.
In FFS, this is the only component type we don't use the API 579 t-min calculator. (We still calculate t-min, but use the ASME S8D1 calc.)
Flat Heads
For these two types of assets, maximum scheduling intervals are 5-year external & 10-year thickness
