API 578 quiz 1

An inspection lot includes:

• all materials from a common source.

• all materials included on the same purchase order.

• all materials of the same material type (i.e. 316 SS).

• all materials from a common source, of the same material type and
  same heat.

Which of the following is not needed on a MTR?

• Date of production & testing

• Source of ore & % of recycled materials

• Chemical specifications
  

• Physical specifications

Incorrect substitution of carbon steel is most likely to be found in:

• any ferritic equipment.

• any non-ferrous equipment.

• chrome equipment.

• stainless equipment.

Which residual element in a carbon steel has not caused increased corrosion
rates in HF acid piping system?

• C

• Cr

• Cu

• Ni

Carbon steel can corrode rapidly in hydrogen-free sulfidation conditions
when the silicon content in carbon steel is:

• < 0.10%.

• > 0.10%.

• < 0.25%.

• > 0.25%.

During construction, the Owner should consider 100% PMI of new
components on:

• all pressure equipment.

• all alloys above P-5.

• exotic alloys.

• high-risk pressure equipment.

Due to the higher potential for material handling mistakes, a higher degree
of PMI should be conducted on materials supplied by:

• European materials manufacturers.

• manufacturers of materials.

• stocking distributors.

• warehouse of owner/user.

The principle employed in the resistivity testing method is known as the _____ (multiple answers)

• triboelectric

• thermoelectric principle

• Seebeck effect

• eddy current sorting

Following methods of material acceptance may be used by owner to evaluate testing results except:

• through a qualitative sorting technique
  

• check results with reference to the nominal amounts of alloying elements specified in the relevant
  materials specification
  

• use a more accurate analysis, if there is a potential rejection of a component when using one portable analysis
  

• by referring to the amount of alloy element in owner's specification as specified by corrosion specialist

When should the owner/operator consider the need to conduct examinations to ensure that inadvertent substitutions did not occur?

• during fabrication stage at manufacturer's workshop

• after fabrication is
  complete at the point of installation

• during fabrication at site

• before components assembly process
