Question 38 : When risk-based inspection (RBI) is chosen to assess the likelihood of a pressure vessel failure, the likelihood assessment must be based on all forms of degradation that could reasonably be expected to affect a vessel in any particular service. The likelihood of failure assessment should be: A. Repeated each time process changes are made that could significantly affect degradation rates or cause premature failure of the vessel. B. Repeated each time process changes are made regardless whether the process changes could affect degradation rates or cause premature failure of the vessel. C. Repeated once every 5 years regardless whether the process changes could affect degradation rates or cause premature failure of the vessel. D. Repeated once every 20 years regardless whether the process changes could affect degradation rates or cause premature failure of the vessel. Question 39 : Which of the following techniques is specifically cited by API RP 577 as having special limitations due to concerns for incomplete fusion? A. GMAW - Globular transfer B. GMAW - Arc transfer C. GMAW - Spray transfer D. GMAW - Short circuiting transfer Question 40 : The results of the visual inspection should be documented to facilitate: A. Follow-up inspection B. Removal of insulation C. Retire of piping D. Corrosion rates Question 41 : An acceptable flow rate for welding on an in-service liquid hydrocarbon piping system is: A. 5.0 ft/sec (1.52 m/s) B. 0 ft/sec ( 0 m/s) C. 7.5 ft/sec (2.78 m/s) D. 2.5 ft/sec ( 0.76 m/s) Question 42: How do you evaluate the effects of fire damage on a piping system?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
