the acceptance criteria
RBI's two Primary Factors Probability Consequence
Two Primary Factors of Consequence of Process Fluid & Volume
Failure
# of new flange assemblies to be inspected Representative
during repairs and alterations
Basis of API 570's Piping Classification Consequence of failure
Method by which process leaks can lead to Auto-refrigeration
brittle failure
Number of CML's to obtain thickness Representative
readings during inspection
CML that must be measured during a CML with earliest renewal date
Thickness Inspection
How relief device intervals are determined Performance
Type of soil that is most corrosive Low Resistivity
Factors that affect the creep rate Time, Temp, & Stress
Mill tolerance for rolled and welded pipe -0.010"
Maximum length of Crack or Incomplete 0"
Fusion allowed on a new weld
