Static Equipment Interview Questions Updated Page

Describe Hydrogen Induced Cracking (HIC).HIC occurs in sour service (H2S environment) where atomic hydrogen enters the steel, recombines into molecules at inclusions, and creates internal pressure that leads to blistering and cracking.

Fully radiographed longitudinal seams, but circumferential seams are spot radiographed. = 1.00 for the shell calculation.

SCC is the cracking of a material caused by the simultaneous presence of three factors: a susceptible material, a tensile stress (applied or residual), and a corrosive environment. Common examples include:

Used in fixed tube sheet exchangers when the differential thermal expansion between the shell and tubes exceeds the allowable stress of the materials.

Thickest requirement due to stress concentration at the knuckle Cheapest and easiest to manufacture Low-pressure or atmospheric vessels

Under UG-46 , you must explain the criteria for manways and handholes based on the vessel's diameter and service type. Describe Hydrogen Induced Cracking (HIC)

A vortex breaker is a cross or baffle plate installed over the bottom discharge nozzle. It prevents the formation of a swirling vortex when fluid drains. This protects downstream pumps from cavitation caused by entrained air or gas bubbles. 3. Heat Exchangers (TEMA Standards) What do the TEMA designations AES, BEM, and AEL mean?

What is the of the position? (e.g., Junior, Senior, Lead Engineer, or Inspector)

Floating roofs float directly on top of the stored liquid surface. They eliminate the vapor space (ullage), which drastically reduces volatile organic compound (VOC) emissions, minimizes product evaporation loss, and reduces the risk of internal fires or explosions. 5. Materials, Corrosion, and Damage Mechanisms What is the Significance of MDMT in static design? SCC is the cracking of a material caused

Q16: You notice a leak from the tell-tale hole of an RF pad during a hydrotest. What does this mean, and what action should you take?

Components that remain stationary during operation. They contain or facilitate fluid flow, chemical reactions, and heat transfer. Examples include pressure vessels, heat exchangers, storage tanks, and piping.
