a) An API 510 inspector, WPS inspector, A Pressure Vessel Engineer

b) An API 570 inspector, a CWI inspector, a piping engineer

c) An owner-user, a B31.3 inspector, an industrial engineer

78) According to API 570, some welds in a piping system that has been subjected to radiography according to ASME B31.3:

a) Will meet random radiograph requirements and will perform satisfactorily in-service without a hydrofest

b) Will not meet random radiograph requirements, and will  not perform satisfactorily in-service even though hydrotested.

c) Will meet random radiograph requirements, and will not perform satisfactorily in-service after a hydrotest

d) Will not meet random radiograph requirements, but will still perform satisfactorily in-service after being hydrotested.

79) How should fasteners and gaskets be examined to determine whether they meet the material specifications:

a) All fasteners and gaskets should be checked to see if their markings are correct according to ASME and ASTM standards

b) A representative sample of the fasteners and gaskets should be checked to see if their markings are correct according to ASME and ASTM standards

c) Purchase records of all fasteners and gaskets should be checked to see if the fasteners and gaskets meet ASME and ASTM standards

d) A representative sample of the purchase records of fasteners and gaskets should be checked to see if the fasteners and gaskets meet ASME and ASTM standards.

80) When checking flange and valve bonnet bolts for corrosion, what type of NDT is usually used?

a) RT

b) UT

c) VT

d) AE

81) What course of action is called for when an inspector finds a flange joint that has been clamped and pumped with sealant?

a) Disassemble the flange joint; renew the fasteners and gaskets. The flanges may also require renewal or repair.

b) Renew all the fasteners and renew the gasket if leakage is still apparent.

c) Check for leakage at the bolts; if re-pumping is contemplated, affected fasteners should be renewed.

d) No action is required since the joint has been pumped with a sealant.

82) All process piping systems must be categorised into different classes. On what are the classifications selection based?

a) Requirements of jurisdiction and the proximity of population areas

b) Potential safety and environmental effects should a leak occur

c) Liability to the owner-user and the requirements of the jurisdiction

d) Access to the systems for inspection and closeness to population areas

83) Inspection strategy based on likelihood and consequence of failure is called:

a) RBI

b) FFS

c) BIR

d) MSOS

84) An RBI assessment can be used to __________ the inspection interval limits in Table 1 of API 570 or the extent of the inspection conducted:

a) Increase

b) Decrease

c) Either a or b above

d) None of the above

85) When an RBI assessment is used to increase or decrease inspection intervals, the assessment shall be conducted on Class 1 systems at a maximum interval of __________ years.

a) 5

b) 10

c) 15

d) 3

86) Listed below are several examples of a CLASS 1 piping system. Which one does not belong?

a) Anhydrous hydrogen chloride;

b) Hydrofluoric acid

c) Piping over or adjacent to water and piping over public throughways

d) Distillate and product lines to and from storage and loading

87) Of the three classification of piping systems, which includes the majority of unit processes and selected off-site piping?

a) Class 3

b) Combination of classes 1 and 2

c) Class 1

d) Class 2

88) Class 3 piping is described as being in services:

a) With the highest potential of resulting in an immediate emergency if a leak occurs.

b) That are flammable but do not significantly vaporise when they leak and are not located in high-activity areas

c) That are not flammable and pose no significant risk to populated areas

d) That are not in classes 1 and 2.

89) Who establishes inspection interval for thickness measurements, external visual inspections and for internal and supplemental inspections?

a) Piping engineer

b) Owner-user or the inspector

c) Chemical Engineer

d) Piping engineer and the jurisdiction
