NEW QUESTION # 57
Equipment used during applicator qualification testing shall be:
Answer: B
Explanation:
According to API 936, duringapplicator qualification testing, the equipment used must beidentical to the equipment that will be used in the actual installation. This ensures that all conditions (air pressure, nozzles, mixers, vibration tools, etc.) accurately reflect field performance and allow for a true demonstration of the applicator's ability to meet the project's quality requirements.
This rule eliminates discrepancies between mock-up performance and production work, which might otherwise compromise the quality of the installed refractory. Testing with alternative or idealized equipment does not represent real installation challenges.
Reference:
API Std 936, Clause 5.2.2:"The same equipment that will be used for the installation shall be used during the qualification testing."
NEW QUESTION # 58
Newly applied cast linings must cure before stripping the forms per the:
Answer: B
Explanation:
The curing of newly installed refractory linings must adhere strictly to manufacturer guidelines to ensure integrity and performance:
"Forms shall not be stripped until the lining has cured per the manufacturer's recommendation."
- API Std 936, Section 5.4.2.1
The manufacturer's recommendations ensure that the product reaches sufficient strength before demolding.
NEW QUESTION # 59
What abrading media is required in the ASTM C-704 abrasion-resistant test?
Answer: D
Explanation:
ASTM C704 specifiessilicon carbideas the standard abrasive media used in the abrasion resistance test for refractories. This test simulates service wear caused by mechanical erosion (e.g., in FCC units). Silicon carbide is used because of its consistent hardness, angularity, and wear characteristics that represent severe operational conditions.
Reference:
API Std 936 references ASTM C704 for erosion-resistant testing and confirms silicon carbide as the specified media.
API TR 977 also documents improvements to test reproducibility with silicon carbide use
NEW QUESTION # 60
The vessel in which coke and residual hydrocarbons are burned off the catalyst and the flue gas is then separated from the catalyst is called
Answer: D
NEW QUESTION # 61
Which of the following is a quality control element?
(This may have more than one correct answer; please select all answers that apply.)
Answer: A,B,C
Explanation:
