API 982 Refractory Inspector Examination Practice Test
API 982 refractory inspection work centers on the condition and installation quality of refractory linings in industrial equipment. Relevant knowledge includes lining layers, refractory brick and mortar, castable materials, metallic anchors, curing requirements, and inspection records. Inspectors use drawings and approved procedures to compare installed work with specified details and identify conditions that could compromise lining integrity or service performance.
Exam overview
About the API 982 Refractory Inspector Examination Exam
Practical inspection decisions include confirming that specified materials and installation steps are supported by approved documents, checking anchor attachment before refractory placement, and assessing brick stability and mortar-joint thickness. Inspectors also examine details at nozzles and other penetrations, where gaps or poor transitions can affect lining continuity. Understanding the hot face and backup layer helps interpret lining arrangements and relate observed conditions to the equipment’s design. Surface condition matters when anchors are welded: loose rust, scale, or debris can interfere with the required attachment process. Inspection records should identify materials, locations, and completed work clearly enough to trace the installation. Safety data sheets provide product hazard and handling information, while curing instructions establish when a lining may be exposed to heat. These tasks connect document review, visual examination, installation controls, and safe work practices.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A refractory installation procedure specifies a minimum curing period before the lining is exposed to heat. What is the inspector's best basis for verifying that requirement?
Show answer
Correct answer: BCuring compliance is assessed against the applicable procedure and documented time and condition records. Surface color, a later temperature reading, or crew size does not demonstrate that the specified curing period was met.
During a visual inspection, one brick in a lining is found to rock under gentle hand pressure. What is the most appropriate inspection response?
Show answer
Correct answer: AA loose or rocking brick may indicate inadequate support or a joint or installation problem. The inspector should document and escalate it for disposition rather than make an unapproved repair or assume heat-up will correct it.
Why is it important to remove loose rust, scale, or debris from a metal surface before welding refractory anchors, when required by the approved procedure?
Show answer
Correct answer: AA clean, properly prepared weld area supports reliable fusion and attachment. Surface preparation does not determine anchor spacing, change the refractory's thermal properties, or guarantee against future corrosion.
A refractory lining drawing identifies a hot face and a backup layer. What does the term hot face indicate?
Show answer
Correct answer: AThe hot face is the lining surface exposed toward the heat source or process environment. A backup layer is generally behind it, toward the supporting structure, although exact arrangements depend on the design.
What is the main purpose of a material safety data sheet or safety data sheet for a refractory product?
Show answer
Correct answer: AA safety data sheet communicates product hazards and guidance for safe handling, exposure controls, and emergency response. It is not a quality acceptance record, installation procedure, or equipment design document.
What is the main purpose of inspecting the shell-side condition before installing a refractory lining, where access and scope permit?
Show answer
Correct answer: AA pre-installation review can reveal surface or substrate conditions that may interfere with the specified lining system. Visual inspection alone cannot determine thermal conductivity or exact process chemistry.
A metallic anchor is specified to be welded to a vessel shell before refractory placement. Which inspection check most directly addresses the anchor-to-shell attachment?
Show answer
Correct answer: AThe attachment weld transfers load from the anchor to the shell, so its conformity to applicable approved requirements is the direct attachment check. Surface color, mortar coverage, and magnetism do not establish weld acceptability.
How to use this practice test
The free US Practice Tests bank contains 50 published practice questions. A session presents up to 20 randomly selected questions and shows results afterward. Use the questions to check how well you apply refractory installation details, inspection observations, and documentation practices; review missed answers by tracing the relevant requirement or physical condition.
Preparation tips
- Compare lining drawings with installation details, and identify the hot face, backup layer, penetrations, and transitions before evaluating field conditions.
- Practice distinguishing acceptable brick and mortar placement from loose units, inconsistent joints, or gaps around nozzles and other openings.
- For anchor-related scenarios, trace the specified sequence from shell surface preparation through welding and attachment verification before refractory placement.
- Review how curing instructions, heat-exposure limits, and product safety data affect installation planning and inspection records.
- For each practice question, identify the governing drawing, approved procedure, or record that would support the inspection decision.
