#1 The ability of a metal to be hammered, or rolled out is called its __________. #2 Reheating a hardened component to a temperature lower than the hardening temperature and then cooling it is known as __________. #3 When hardened metal is heat-treated by a process known as tempering, what metallurgical properties are achieved? #4 When metal is tempered, it becomes __________. #5 What is the purpose of heat treating steel? #6 Monel metal is an alloy composed mainly of __________. #7 When a metal is undergoing heat treatment, what happens when the metal is heated above its critical temperature? #8 When a metal is undergoing heat treatment for the purposes of annealing, besides refining the grain structure, what is the determining characteristic of the metal? #9 When a low carbon steel is undergoing heat treatment for the purposes of casehardening, what is the process that distinguishes this procedure from other hardening methods? #10 What effect does preheating, concurrent heating, or post heating have on a welding a joint? #11 What is meant by the term tensile strength of a material? #12 What is meant by the term toughness as it applies to a material? #13 Referring to the illustration, suppose after initiating the oil discharge mode, the oily- water separator fails to come out of the oil discharge mode in a timely fashion. Cracking open the upper sampling valve reveals the presence of water exiting under a positive pressure. What is most likely the cause? GS-0175 #14 Referring to the illustration, what would be the result if the lower oil/water interface detection probe became faulty? GS-0175 #15 If item "1" shown in the illustration is a compound gage indicating zero psig and the water level in the bilges is one foot high, the unit is __________. GS-0153 #16 If item "1" in the illustrated oily water separator indicates an abnormally deep vacuum, which of the following conditions is the most probable cause? GS-0153 #17 The line labeled "G", as shown in the illustration, would be identified as the ______. GS-0175 #18 What is the normal direction of flow through the device shown in the illustration while operating in the processing mode? GS-0153 #19 The line labeled "E", as shown in the illustration, would be identified as the ______. GS-0175 #20 The components indicated as "7" and "8" as shown in the illustration, are known as the __________. GS-0153 #21 The function of item "7" shown in the illustration is to __________. GS-0153 #22 The line labeled "C", as shown in the illustration, would be identified as the ______. GS-0175 #23 When the oily water separator, shown in the illustration, is in operation and processing clear bilge water, what should be the internal water level? GS-0153 #24 How would the pressure setting of the illustrated self-contained, internal-pilot, piston- operated steam pressure-reducer be reduced to a lower set point? GS-0044 #25 Suppose the illustrated self-contained, internal-pilot, piston-operated steam pressure- reducing valve is part of a 600-to150 psig reducing station. If there was an increase in demand for steam downstream, what statement correctly represents how the valve would initially respond? GS-0044 #26 In the illustrated self-contained, internal-pilot, piston-operated steam pressure- reducing valve, what statement is true concerning the opening and closing forces acting upon the control diaphragm? GS-0044 #27 How would the illustrated valve respond to a complete loss of charge from the remote bulb-to-control diaphragm power element if the valve is used as a temperature control valve for a steam-heated heavy fuel oil service heater? Refer to Illustration GS-0045 #28 In the illustrated self-contained, internal-pilot, piston-operated temperature control valve, what statement is true concerning the pilot and main valves? GS-0045 #29 Suppose the illustrated self-contained, internal-pilot, piston-operated temperature control valve is part of the temperature control system for a steam-heated heavy fuel oil service heater for a steam boiler. If there was an increase in demand for fuel by the boiler, what statement correctly represents how the valve would initially respond? GS-0045 #30 Referring to the illustrated huddling-chamber safety valve, what statement concerning the blow down adjusting ring (B) is true? (SG-0018)
