Q. 8/30: If environmental cracking is detected during internal inspection of pressure vessels, what should the inspector do ?
The inspector should designate appropriate piping spools upstream and downstream of the vessel to be inspected if piping is susceptible to environmental cracking.
The inspector should consult with a metallurgical engineer to determine extent of the problems
The inspector should review history of adjacent piping to determine if it has ever been affected.
The inspector should consult with a piping engineer to determine the extent of the problems.

Q. 10/30: What course of action should be followed it a coating of coke is found on the interior of a large pipe of a reactor on a Fluid Catalytic Cracking Unit ?
Determine whether such deposits have active corrosion beneath them. If corrosion is present, thorough inspection in selected areas may be required.
The coke deposits should be removed from the area for inspection.
The coke deposits may be ignored – the deposits will probably protect the line from corrosion.
Consult with a Process Engineer and a Metallurgist on the necessity of removing the coke deposits.
