API 571 Exam #1 VERSION 2023 /2024 VERIFIED QUESTIONS AND ANSWERS LATEST UPDATE ALREADY GRADED A Amine corrosion refers to the gener al and/or localized corrosion th at occurs principally on carbon steel in amine treating processes. Corrosion is not cau sed by the amine itself, but results from dissolved acid gases (COz and HzS), amine degr adation pr oducts, heat stable amine salts and other contaminants. Amine corrosion primarily occurs in which materials? a) carbon steel b) 300 series st ainless steels c) ferritic stainless st eels d) nickel alloys A 5.1.1.1.2 What is the most important factor related to mechanical fatigue of a piece of equipment? a) material selection b) equipment design c) operating conditions d) opera ting temper atures B 4.2.16.3 Temper embrittlement primarily occurs in: a) Some low alloy st eels as a result oflong term exposure from 650oF to 1070oF b) All carbon and alloy steels as a result of long term exposure from 650oF to 1070oF c) All cast irons and all carbon steels above 800°F d) 2.25Cr -1Mo steels at 900oF D 4.2.3.2 a) Cracking of a me tal due to stress relaxation during PWHT or in service at elevated temperatures is most often observed in heavy wall sections. This is called: a) stress relieving corrosion cr acking b) reheat cracking c) hydrogen induced stress relieving cracking d) SOHIC B 4.2.8.2 Creep can occur in: a) All metals and alloys. b) Only ferrous metals. c) Only in weldments of all metals and alloys. d) All carbon steels. A 4.2.8.2 Which combination of joined metals is most likely to corrode in an aggressive environment when a suitable electrolyte is present? a) steel -zinc b) steel -magnesium c) steel -aluminum d) titanium -zinc D Table 4 -6 Visual examination of suspected erosion -cor.rosion areas is only one means of inspect ion , others include: a) UT or RT to detect the extent o f metal loss b) corrosion coupons and on -line corrosion monitoring electrical resistance probes c) IR scans to detect refractory loss on stream d) all of the above D 4.2.14.7 a) b) c) Naphthenic acid corrosion is suspected on a high velocity outlet line of a crude oil heater. What is the best method for inspecting for damage? a) spot UT thickness measurements b) RT followed by UT thickness measurement c) RT should be the primary detecti on method d) thermography B 5.1.1.7.7 a) At what oxygen content would many metals become flammable even at low pressures, whereas they are non -flammable in air? a) >10% b) >25% c) 20 -40% d) >40% B 4.2.20.1 What area of a heater burning fuel oil with numerous impurities would first suffer damage from fuel ash corrosion. a) shock tubes b) radian tubes c) tube hangers and supports d) convection tubes C 4.4.6.4 c) Hydriding of titanium is a metallurgical phenome non in which hydrogen diffuses into the titanium and reacts to form an embrittling hydride phase. This can result in a complete loss of ductility with no noticeable sign of corrosion or loss in thickness. Galvanic contact between titanium and more active m aterials such as carbon steel can have what affect? a) promotes damage b) insulates the galvanic system and decreases damage c) insulates the galvanic system and decreases damage only if pure titanium is used (not titanium alloys) d) all of the above A 5.1.3.2.3 c) When connected to a more anodic material in cooling water: a) titanium may suffer severe hydriding embrittlement b) titanium may suffer severe hydriding embrittlement below 180°F (82°C) c) titanium becomes immune to corrosion d) titanium becomes almost immune to corrosion A 4.3.4.3 k) What form of fatigue cracking develops under the combined effects of cyclic loading and corrosion and are evidenced by ver little plastic deformation where the final fracture may occur by mechanical overload accompan ied by plaslic deformation? a ) corrosion fatigue b) mechanical (vibration) fatigue c) thermal fatigue d) all ofthe a bove
