As you all know that the Refractory Personnel (API-936) exam is the most challenging exam, since it's difficult to find preparation material for passing the API API-936 exam. ITExamSimulator provides you with the most complete and comprehensive preparation material for the API API-936 Exam that will thoroughly prepare you to attempt the API-936 exam and pass it with 100% success guaranteed.

Individuals who pass the API-936 certification exam are awarded a certificate that is valid for three years. To maintain their certification, individuals must complete a minimum of 20 hours of continuing education each year and pass a recertification exam every three years.

Obtaining the API-936 certification demonstrates a high level of expertise in refractory materials engineering and is a valuable asset to professionals working in the petroleum and petrochemical industries. It is also a requirement for some positions in these industries, and many companies require their employees to hold this certification. The API-936 certification is valid for three years, after which the holder must pass a recertification exam to maintain their certification status. Overall, the API-936 (Refractory Personnel) Exam is an essential certification program for professionals involved in the design, installation, and maintenance of refractory materials in high-temperature process environments.

API-936 exam is a rigorous and challenging exam that requires a thorough understanding of refractory materials and their applications. API-936 exam consists of 120 multiple-choice questions, and candidates have four hours to complete the exam. To pass the exam, candidates must achieve a score of at least 70%.

API Refractory Personnel Sample Questions (Q51-Q56):

NEW QUESTION # 51
Fused silica aggregate is used as a raw material in a castable providing

  • A. Low thermal conductivity and low thermal expansion
  • B. Low thermal expansion
  • C. None of the above
  • D. Low thermal conductivity

Answer: A


NEW QUESTION # 52
In the absence of owner specification, which party or individual sets the temperature limits for refractory and mix water?

  • A. Independent refractory laboratory
  • B. Inspector
  • C. Contractor
  • D. Manufacturer

Answer: D

Explanation:
When the owner does not provide explicit temperature criteria for mixing and placement, the refractory manufacturer's instructions prevail:
"If not specified by the owner, the refractory manufacturer's published recommendations shall be followed for temperature limits of both material and mixing water."
- API TR 980, Section 4.5.2
Thus, Option B is correct.


NEW QUESTION # 53
Compositions of ground refractory materials which require relatively high temperatures for the development of an adequate bond (commonly called the ceramic bond) is called

  • A. heat setting refractories
  • B. none of the above
  • C. air and heat setting refractories
  • D. air setting refractories

Answer: A


NEW QUESTION # 54
In accordance with TR 980, when curing a high-purity, low-cement castable for a high-temperature unit, which of the following sequences ensures minimum cracking risk?

  • A. Accelerated drying using forced air at 400°F for 12 hours
  • B. Dryout using open flame burners after form removal
  • C. Air curing for 24 hours, followed by controlled heating ramp of 50°F/h up to 600°F
  • D. Steam curing for 48 hours followed by firing at 1500°F

Answer: C

Explanation:
TR 980 outlines curing and dryout best practices for monolithic refractories. For high-purity low-cement castables, gradual heat-up is necessary to avoid thermal shock and cracking:
"A minimum 24-hour air cure at ambient temperature should be followed by a controlled dryout ramp not exceeding 50°F (28°C) per hour up to 600°F (316°C)."
- TR 980, Section 6.4.2


NEW QUESTION # 55
Which of the following is false per the requirements of API Standard 936?

  • A. Density shall be determined using cubes or erosion plates and linear change bars.
  • B. Cold crush strength is determined using two 4-1/2 in. (144 mm) × 4-1/2 in. (114 mm) × 4-1/2 in. (114 mm) cubes.
  • C. Permanent linear change is determined with one 2 in. (50 mm) × 2 in. (50 mm) × 9 in. (230 mm) specimen.
  • D. Abrasion resistance is determined using two 4-1/2 in. (114 mm) × 4-1/2 in. (144 mm) × 1 in. (25 mm) specimens.

Answer: B

Explanation:
According to API Standard 936, the correct specimen dimensions for cold crush strength testing are:
"Test specimens for cold crushing strength shall be2 in. (50 mm) cubesamples prepared in accordance with ASTM C133."
-API Std 936, Section 6.4.2
This directly invalidates option A, which incorrectly states the specimen size as 4-1/2 inches.
For the other options:
Option B - Density determination:
API 936 states that density shall be measured using the same specimens used for linear change and abrasion resistance:
"Bulk density shall be determined using the same specimens prepared for the linear change and abrasion resistance tests."
-API Std 936, Section 6.4.3
"These specimens include cubes, linear change bars, and erosion plates."
-Appendix A, API Std 936
Option C - Abrasion resistance specimen size:
"Two 4-1/2 in. × 4-1/2 in. × 1 in. (114 mm × 114 mm × 25 mm) specimens shall be prepared for abrasion resistance testing."
-API Std 936, Section 6.4.4
Option D - Permanent linear change specimen size:
"Permanent linear change (PLC) is determined with a bar 2 in. × 2 in. × 9 in. (50 mm × 50 mm × 230 mm) cast in steel molds."
-API Std 936, Section 6.4.1
Therefore, Option A is the only false statement.
