... previously. Resist the temptation to immediately assign the same root cause to failures that appear similar. If you fall into that mindset, you will give the same recommendation—which obviously did not solve the problem the first time. For example, 16 years ago I was given a seven-ply bellows made from...

..., and the damages to the plant and the community were inevitable. It may be recalled that the court of inquiry concluded that when the leaking reactor No. 5 was replaced by a dog-leg pipe with bellows at the two ends, to bridge reactors 4 and 6, there was no proper design study, no proper consideration...

... the outlet of reactor 4 and the inlet of reactor 6 were at different levels, the two reactors were joined by an inadequately supported bypass assembly consisting of a “dog-leg” pipe of three segments between two expansion bellows at their ends. The fact that bridging the gap with a span of about 6 m (20 ft...

.... Bellows, a device used for blowing air into a fire, were used to raise the temperature. With further refinements, this process was used for many centuries to produce what we call “ wrought iron .” During the many early years that humans used iron, wrought iron was the dominant form. It could be worked hot...

... of the first approach is the production of “wootz” steel in India, which dates back to about 350 B.C. ( Ref 6 , 7 , 9 ). Iron ore was smelted with charcoal in forges; air was forced into the charge through tuyeres with bellows, enabling high temperatures to be attained. Nevertheless, temperatures were...

.... Thermal fatigue may be prevented in many parts by designing curves rather than straight lines into the system. When this is done, heating and cooling cycles simply cause distortion of the curves, rather than forming tensile residual stresses upon cooling. Expansion loops and bellows in elevated...
