The shell of a tower burst during a hydraulic test
Thread Content
During the pressure test of a pressure vessel, the pressure-bearing components break; please watch the video at the link above – the shell cracks, which is extremely dangerous!
There are essentially two types of such failures: one is damage during pressure testing caused by uneven stress in the material, resulting from the fact that no appropriate heat treatment was carried out after manufacturing； Is another estimate manual operation? The possibilities in other areas are relatively low. Such as material quality and design choices. They are all very mature products, so it’s hard for problems to arise.
This situation is relatively rare, so intensity issues can be ruled out immediately, as the test pressure is several times lower than the burst pressure. Careful analysis is required, including the crack openings and the pattern of the cracks.
Materials, the actual welding process, and heat treatment are the key points for cause analysis!
There was a case where the tower cracked before a hydrostatic test could be conducted, after the internal components had been welded
It can’t be that the hydraulic test pressure exceeded the requirements specified in the drawings, right?
Overpressure? If it weren’t for the quality! Or ultra-long lifespan!
Actually, the original poster didn’t provide too many details; I’m just mentioning one possibility. Actually, it seems that problems with the welds are more likely to occur.

With what material, there might be issues with the welding quality
