, ✔✔According to API 510 the inspector in consultation with whom, should determine
when it is necessary to remove deposits or linings to perform adequate inspection -
✔✔The corrosion specialist

welds - ✔✔Shall not be less than 2T where T is the thickness of the shell
✔✔For vessels fabricated with carbon and low alloy steel, general and local metal loss
can result from - ✔✔Naphtenic acid corrosion
✔✔Which readings taken within the area of examination of a CML shall be used to
calculate corrosion rates - ✔✔The thinnest or an average of several measurements
✔✔The primary purpose for preheating carbon and low alloy steel prior to welding is to -
✔✔Reduce the chance for delayed cracking
✔✔If the requirements of 510 are more stringent than the jurisdiction requirements -
✔✔The requirements of API 510 shall govern
✔✔The installation of a new nozzle that does not require reinforcement - ✔✔Shall be
approved by an engineer
✔✔API Publication 2201 on hot tapping and in service welding covers - ✔✔Safety
aspects

found - ✔✔API 578
✔✔What is the inspectors role regarding preheat temperature used in making welding
repairs - ✔✔The inspector should assure that the minimum preheat temperature is
measured and maintained
✔✔What are indications - ✔✔A response or evidence resulting from the application of
NDE
