What is the primary purpose of a floating head? (Answer: To allow for thermal expansion movement). Tube Sheet Design:
Identified by its exact Outside Diameter (OD) and wall thickness (often measured in Birmingham Wire Gauge - BWG or inches). Tubes are used in precise structural applications and heat transfer components like heat exchangers and boilers.
Scenario 1: A shell-and-tube heat exchanger handling sour gas shows sudden shell-side pressure drops. What do you suspect? static equipment interview questions updated
: What are the various "loadings" defined under UG-22 that must be considered in vessel design? (e.g., internal/external pressure, weight of the vessel, wind, and seismic loads) Nozzle Design
Fully radiographed longitudinal seams, but circumferential seams are spot radiographed. = 1.00 for the shell calculation. What is the primary purpose of a floating head
A: Low sulfur (S ≤ 0.002%), calcium treatment to modify inclusions, low phosphorus (P ≤ 0.015%), controlled carbon equivalent (CE ≤ 0.43), and normalized or TMCP rolling to produce a uniform, fine‑grained microstructure without centerline segregation.
contains moving parts to transfer fluid or energy (e.g., pumps, compressors, turbines). Tubes are used in precise structural applications and
Q: Describe an RBI approach for static equipment. A: Risk-Based Inspection (RBI) ranks equipment by likelihood and consequence of failure. Collect data (design, materials, process conditions, inspection history), assess degradation mechanisms, quantify risk, and define inspection intervals and techniques to reduce risk to acceptable levels. Update RBI based on inspection findings.
