Improper fit Poor welding Improper heat treatment All the above</p> <p>Sample of API 572 Question53. The external inspection of a pressure vessel should start with: 1. 2. 3. 4. Vessel foundation and anchor bolts Ladders, stairways, platforms or walkways connected or bearing on the vessel Nozzles and connecting piping Protective coating and insulation.</p> <p>Sample of API 572 Question54. If an internal inspection of a vessel is not the initial one, the first step is to: 1. 2. 3. 4. Make a walk around visual check of the vessel Review the previous records of the vessel to be inspected Check with the vessel operators for unusual operating conditions Make a preliminary manway inspection</p> <p>Sample of API 572 Question88.
