Answer: Spherical heads are the strongest but most expensive to fabricate. Ellipsoidal (2:1) heads are the industry standard for high-pressure vessels because they offer a good balance of strength and cost.
Uses high-frequency sound waves to measure wall thickness and locate internal cracks or flaws.
Unlike primary stress, which is necessary to satisfy laws of equilibrium, secondary stress is self-limiting and caused by localized structural constraints or thermal gradients. Code & Compliance Questions static equipment interview questions
Remind readers that it’s not just about memorizing codes; it’s about understanding safety and risk management .
How do you protect a pressure vessel from overpressure scenarios? Answer: Spherical heads are the strongest but most
How do you document a repair under API 510 vs NBIC Part 3? A:
What is the difference between a Seamless and a Welded pipe, and where would you use them? Unlike primary stress, which is necessary to satisfy
Skirts suffer from “bottom corrosion” due to moisture/debris traps. Good designers add a weep hole.
Using the circumferential (hoop) stress formula: [ t = \fracP \times RS \times E - 0.6P + C.A. ] Where:
