Won’t the material break when the bellows are hydraulically formed due to yield?
Thread Content
Since the material has reached its yield point, in a strict sense the bellows is damaged. If it is placed back in the pipeline to absorb deformations, wouldn’t that be extremely dangerous? I don’t understand the reasoning behind this; please advise!
What about the experts? There is a statement in \"Practical Techniques for Waveform Expansion Joints\" that experiments have shown that the side walls of the bellows bulge under internal pressure and exhibit yield behavior; however, it has not yet been possible to prove that this affects the integrity of the bellows. Is this considered an explanation?
