Inconel pipe crush-repair proposal (Coast Guard student case, 2014)
Appears in 1 lecture.
Appearances across the corpus
A Coast Guard student describes a proposed (but unused) repair scheme: mechanically compressing a cracked Inconel pipe to introduce compressive residual stresses at the crack and prevent growth. Tom has never heard of this approach; reasons through it on the spot, acknowledging the mechanics work but expressing skepticism about it as a critical-application solution.
Student: We had a problem with some cracks in some of the Inconel that we had, and one of the solutions that was going to be proposed — not one that we used — was to basically crush the pipe in order to close the cracks. How viable is that as a long-term solution?
