✍️ Sample Piping Questions & Answers
1. What nondestructive method is best suited for detecting stress corrosion cracking (SCC) in stainless steel piping?
Eddy current and PAUT are effective for detecting SCC cracks in stainless steel; MT cannot be used on non-ferromagnetic austenitic stainless steel.
2. What does 'deadleg inspection' specifically look for in process piping?
Deadlegs accumulate corrosive by-products, sediment, and microbiological growth in stagnant fluid, often causing rapid corrosion that requires focused inspection attention.
3. In isometric drawings for piping, what does a spool represent?
A spool is a prefabricated piping assembly, typically consisting of pipe, fittings, and sometimes valves, fabricated in a shop and installed as a unit in the field.
4. What does 'weld map' refer to in pipe fabrication?
A weld map is a drawing that identifies and numbers every weld on a pipe spool, allowing traceability to the welder, procedure, inspection results, and PWHT records.
5. What is the most common NDE method used for measuring remaining wall thickness of in-service piping?
Ultrasonic thickness measurement (UTM) using a UT gauge is the standard method for measuring remaining pipe wall thickness from the outside without requiring process shutdown.
6. What does ASTM A193 Grade B7 specify?
ASTM A193 B7 is a chromium-molybdenum alloy steel stud bolt used in high-pressure, high-temperature flanged joints, offering superior strength compared to carbon steel bolts.
